Costly fitness regime: Search for perfect body may lead to grave

While many citizens find the health benefits offered by jogging to be admirable, many people are stomped due to cases of joggers who have fallen victim to robberies or murder by louts and inebriated drivers, aided by a general lack of safety confronting many residents across communities, VICTOR AYENI writes

In an age of burgeoning awareness about the many benefits of physical activity and fitness regimens, more Nigerians are turning to one of the most efficient forms of exercise – jogging.

It is no longer farfetched to see both young and middle-aged individuals jogging singularly or in groups across various residential areas in major cities across the country.

Unfortunately, despite the promising prospects offered by jogging, many Nigerians are confronted by risks that range from muggings to accidents to being murdered while running towards wellness.

On December 25, 2022, as the arch of sunlight shone on the Idu-Karmo district of the Federal Capital Territory, shrill cries of mourning marred the emerging Christmas celebration when a father of four, Usman Ahmad, was found in a pool of blood in the area.

The deceased, who was an employee of the Nigerian Upstream Petroleum Regulatory Commission, had set out early in the morning to go on a jogging routine, but his lifeless body with stab wounds was found in the afternoon about half a kilometre from his Ochacho Estate residence in Abuja.

Saturday PUNCH gathered that Usman had just relocated to the estate three months before his death and after he bagged a master’s degree in Energy Oil and Gas Economics from the University of Dundee, United Kingdom.

During Usman’s burial in Barkin Ladi, Plateau State, his father, Hussaini Ahmad, said he received the tragic news of his death from his wife a day after it happened.

“The wife of the deceased called me on Sunday, telling me that Usman was nowhere to be found since he left for a morning walk. I was later told that his corpse had been found. His friends and other good Samaritans recovered the body and brought it to Barkin Ladi for burial,” he told Daily Trust.

Also speaking, one of Usman’s neighbours, Kasim Abdullahi, disclosed that the deceased normally went out for morning walks every weekend, the last of which was on Saturday when the incident happened.

He said, “On Sunday morning at around 6:38 am, Usman sent me a WhatsApp message asking what time we were going for the walk. Unfortunately, I had to drop my family at Jabi Motor Park as I was unable to make it the day before.

“Around 11 am, Usman’s wife came to my house to ask my wife whether we went out together as he had not returned. I quickly got up from bed, came downstairs, and met Usman’s wife together with another friend’s wife who I happened to know.

“I then went to our estate gate to inquire whether anyone had seen Usman passing in the morning to which they said they could not recall.

“I went back home, got into my car, and followed the route we used for our morning walk with Usman. I also put a call to Usman’s childhood friend and he quickly came to our estate where we met.

“We then decide to report Usman as missing to the nearby police station. At the station, we described Usman, his phone numbers, and what he was wearing that fateful day as well as the last time he was seen. We were then informed that it would take 24 hours before a signal could be raised but that we should continue the search and rescue effort.”

Abdullahi added that he received news that his friend’s body was found while he performed ablution for Zuhr (Muslim noon) prayer the next day.

“I saw Usman’s lifeless body, with his joggers soaked in blood as a result of a stab on his right lap. His phone was nowhere to be found, which suggested that phone snatchers could be behind his untimely death,” he added.

Abdullahi, however, believed that Usman might have put up a resistance to mobile phone snatchers who accosted him while jogging which infuriated them and made them stab him with a knife.

The FCT police spokesperson, Josephine Adeh, confirmed the incident, adding that Usman was confirmed dead by experts.

“He was later discovered around 2 pm by a search party organised by the Karmo Divisional Police Headquarters upon the receipt of the information, with visible bodily injuries.

“He was confirmed dead by experts on the crime scene and the police investigation team was present to remove the corpse and take necessary preliminary investigative actions,” she added.

Stabbed, robbed while jogging

In a similar ill-fated incident, a member of the National Youth Service Corps identified as Chalya Joel was brutally murdered by suspected armed robbers in Kaduna State.

Like Usman, the University of Jos graduate was killed while jogging on the morning of Wednesday, October 18, 2023.

The Director of Press and Public Relations of the NYSC, Eddy Megwa, in a statement issued on October 19, 2023, noted that after the deceased completed her morning devotion with other corps members at the Barnawa Government Residential Area in, Kaduna, where she resided, she proceeded to jog.

Joel was believed to have been accosted by hoodlums who stabbed her and made away with her phone. The corps member’s colleagues were reportedly alerted by a kind-hearted passerby and she was rushed by the management of the NYSC to Harmony Hospital Limited in Barnawa, for prompt medical attention.

Unfortunately, she passed on.

For several days after Joel’s murder, friends of the deceased all came to mourn her on Facebook and X (formerly Twitter).

“No. What is really happening to Jossite and the special education department? We haven’t finished mourning Kekefas Emmanuel and now it’s Chalya, brutally killed in Kaduna during her morning jog while serving her fatherland.

“May your killers know no peace Chalya. This is too much to bear,” one Comfort Elisha wrote on her Facebook page.

Giving details on the murder, the state Police Public Relations Officer, Mansir Hassan, said Chalya was killed by miscreants on motorcycles.

“It’s a very tragic incident. She was performing her early morning jogging when some miscreants on motorcycles pounced on her. The victim’s name is Grace Chalya Silas. She was a corps member serving in Kaduna South.

“When the case was reported to the police, operatives responded swiftly and moved to the scene of the crime where they saw the victim in the pool of her blood. She was rushed to the clinic, where she was later confirmed dead.”

Killed by addled drivers

In an interview with Saturday PUNCH last month, a retired professor of Physics at the University of Lagos, Olayinka Olatunji, described how his first son’s life ended tragically after he was knocked down by a vehicle while jogging.

The 90-year-old widower broke down in tears as he recounted how his son, who he said was the most intelligent of his children, got an appointment in a finance company in Lagos about the time when he decided to go jogging.

“I had four children one of whom is now late and incidentally the most brilliant of them. He attended the University of Lagos International School where he was taught all sorts of things and given good mental orientation. He got an appointment in one of these finance companies.

“He liked jogging, so he went jogging in Lagos and was knocked down by a vehicle. He was taken to a hospital where a doctor who examined him wrote an X-ray in the morning, while he was bleeding internally. Unfortunately, he passed on before daybreak.

“I wrote to the Chairman of the House Committee on Health in the House of Representatives protesting the action of the said doctor. That was how my first son died,” he stated, wiping away his tears.

Similarly, on April 21, 2020, several commuters and residents of the Sangotedo area in Lagos were thrown into mourning when a driver drove against traffic rules and crushed two young men while they jogged early in the morning.

An Instagram user, @originaltombo, who shared a video of the incident on the social media app, said the siblings had just finished assisting their mother in displaying her tomatoes for sale when they decided to go jogging.

According to her, they had barely begun when they were run into by the vehicle. Three other people were also said to have sustained serious injuries during the crash and were treated at an undisclosed hospital.

In the graphic video that was shared on Instagram, the lifeless bodies were seen inside the drainage, with the unoccupied damaged vehicle surrounded by several sympathisers and passersby.

In the viral video, some of the passersby were heard saying, “The driver took ‘one-way’,” in the Yoruba language.

Worrying figures on road crashes

The death of the siblings re-echoed the dangers joggers face amid reckless driving by some motorists.

Last Friday, the latest data released by the National Institute of Statistics in Abuja, revealed that a total of 2,717 accidents occurred in the fourth quarter of 2023.

However, the figures indicated a decrease of 33.12 per cent compared to the same period in 2022, when 3,617 accidents were recorded.

The figures showed that 1,104 men (adults and children) lost their lives in accidents in the time under purview, accounting for 83.45 per cent of the 1,323 deaths recorded.

Women accounted for 16.55 per cent of deaths with a total of 219 people, adults and children combined.

On Tuesday, the Lagos Sector Command of the Federal Road Safety Corps said it recorded 342 road accidents that claimed 22 lives in Lagos State between January and February 2024.

The state Sector Commander of the FRSC, Babatunde Farinloye, disclosed this in an interview with PUNCH Metro.

Also, The PUNCH had reported that the FRSC Corps Marshal, Dauda Biu, had disclosed that a total of 5,081 people were killed in various road traffic crashes across the country in 2023.

Biu noted that 10,617 road traffic crashes were recorded and 31,874 were injured stressing that the figures represented a significant reduction in road crashes, fatalities, and injuries compared to the data recorded in 2022.

The World Health Organisation estimated over 1.3 million people die every year as a result of traffic accidents worldwide, and more than half of all road traffic deaths are among vulnerable road users including pedestrians, cyclists, and motorcyclists.

 However, findings by our correspondent from data provided by both the NBS and Statista indicated that drunk driving, brake failures, speed violations, light or sign violations, wrongful overtaking, dangerous driving, and unsafe lane changing were some of the most common causes of car crashes and deaths across the country.

Lagos jogger stabbed to death

On February 26, 2015, residents of the Morogbo area of Badagry, Lagos, made a grisly discovery: the body of an unidentified man who was stabbed to death.

According to the police report, the man’s corpse was dumped in a bush near Igborosun village after he was stabbed in the stomach and jaw by the murderer(s). The incident was brought to the notice of the police by a resident of the area, Pastor Stephen Hensu, of the Celestial Church of Christ, Okiki Imole branch, Badagry.

Narrating how he saw the corpse, the 50-year-old pastor said, “On the day of the incident, February 26, 2015, around 9 am, I left my church for a meeting of the shepherds at Araromi.

“While I was there, I received a phone call from my wife informing me that some people coming from Igborosun village saw a corpse in a bush in our area.”

After the police were notified of the body that was found, a source within the force said nobody had come forward to identify the deceased.

“Looking at the corpse shows that the man was a sportsman and he was out jogging that morning when he was attacked and killed. He was killed and his corpse was dumped in the bush.

“He had deep cuts in his jaw and stomach. Nobody knows his name and none of his family members has come forward to identify him, which will help us in investigations,” the source said.

Veteran journalist killed by hit-and-run driver

In another tragic example of the risks joggers face, a veteran journalist, and associate publisher of the Entertainment Weekly newspaper, Dimgba Igwe, died hours after he was hit by a driver while jogging on September 6, 2014.

The late journalist had set out on a jogging exercise in the Okota area of his Lagos residence on the fateful Saturday morning when he was knocked down by a hit-and-run driver.

Although Igwe was found alive and was rushed to hospital after the accident, he was said to have been pronounced dead on arrival at the Lagos State University Teaching Hospital in Ikeja.

A veteran journalist and author, Mike Awoyinfa, who was a friend of the deceased, lamented that Igwe could have lived if the healthcare system had not failed him.

“Why must all my friends and heroes in journalism die so cruelly, landing on the front page? My editor, Dele Giwa, died the same way: killed dastardly through a letter bomb on October 19, 1986. And up till today, the riddle of his death remains unsolved.

“It has become ‘A riddle wrapped in a mystery inside an enigma,’ to use a phrase by Winston Churchill. Like Giwa, Dimgba Igwe, in the throes of death was crying, ‘I don’t want to die.’

“For four hours, he was bleeding on the road to Golgotha. No ambulance. No oxygen mask. No Samaritan hospital. From St. Raphael Hospital to the General Hospital, Isolo, where there was no surgeon to attend to him, it was the story of Nigeria’s systemic failure as a country. He finally gave up at Lagos State University Hospital, Ikeja.

“If I am angry at all, it is not with the bloody coward who killed him and fled in panic. I will forgive the hit-and-run killer. And the Dimgba Igwe I know, will forgive the man who killed him. What I cannot forgive is a nation with health institutions that can do nothing, once your life is in danger. It’s the same story all over Nigeria,” Awoyinfa wrote in a column published by Daily Post.

 Jogging requires safety – Fitness enthusiasts

 A fitness expert, Mike Nwagbara, explained that though jogging had many health benefits that more citizens need to explore, there was a need for people to ensure that their safety is guaranteed and to be mindful of their environment.

“It is an exercise that boosts your cardiovascular health and keeps workouts interesting because it boosts your motivation, so it is recommended for people who want to build their muscles, stamina, and aerobic capacity. Jogging helps you to lose fat and gain more energy.

“But while jogging is good, it’s important for persons who desire to be fit to be mindful of their environments and ensure that their safety is guaranteed while they jog. If they can’t ensure this, they can register in a gym or get a trusted trainer who will prescribe them a regime that suits their schedule,” Nwagbara noted.

But a fitness trainer, Emmanuel Adeoye, in a chat with Saturday PUNCH, lamented that unsafe driving and certain habits could predispose people who regularly jog to dangers.

He explained, “Jogging on Lagos roads is a dangerous sport because the danfo (commercial) drivers always behave like the devil’s firstborn. With my experiences so far, I would liken jogging on Lagos roads to the devil test-running a new version of Temple Run with one’s life.

“Some of the drivers are already in an induced state when they are turning the wheels in the morning and could crush you before they know you are jogging. That’s why I don’t jog alone, I do it with my fitness partners in the area.

“I have stopped listening to music while jogging on the streets because it’s dangerous in Nigeria. Whether you are having a walk, cycling, or jogging, I won’t advise you to have your ears plugged in because there are drunk drivers, and there are also robbers, rapists, and murderers roaming the streets.”

A movie scriptwriter and fitness enthusiast based in Ogun State, Abiola Omolokun-Ola, told our correspondent that jogging with fellow joggers had proven to be the safest for him.

He said, “I don’t jog alone and it’s only on selected Saturdays with other gym mates to a specific limited distance. When we hit the road in groups it makes it inspiring.

“In addition to this, we are all familiar with the area and we don’t jog while it’s still dark. I find it dangerous to be jogging along the Lagos-Ibadan Expressway while it’s still dark. Even trekking has become very dangerous because you can be attacked by hoodlums or even kidnapped.

“So before you start jogging, let your family know where you are going, and how they can reach you, but the safest is to jog with a group of friends or gym partners.”

Similarly, an Ibadan-based fitness enthusiast, Obinna Onyebuchi, told Saturday PUNCH that he preferred to jog when the day was bright enough for him to see his environment.

“Jogging is a good exercise that helps prepare the body for a workout and minimise injury. In fact, before I touch any weight, I jog for at least a mile so that my blood is warmed up.

“But while I take priority over my body, I also have to ensure my safety. For instance, I usually wait until the day has dawned properly before I set out. I know with that, I can clearly see who is coming or moving and I can see the ground I am stepping on.

“The road around my area could be a challenge because those not familiar with the terrain could fall into a ditch or step on dangerous objects if they can’t see properly.

“There is also a probability that an oncoming vehicle or motorcycle could knock someone down and that usually happens when you jog before sunrise. I avoid terrains where cars or bikes are known to pass. I also avoid jogging in unknown terrains or bush paths and I don’t wear earphones so I can hear what’s going on around me,” he stated.

Poor road infrastructure, Saturday PUNCH learnt, is a factor that can predispose people passionate about jogging to hazards. As such, treadmills are recommended.

Speaking on this, a Lagos resident who enjoys keeping fit, Donald Eke, “When you look at several other areas in the state, you will notice that there is still much to be done for people to be safe while jogging. First of all, there is a need for good roads and sidewalks.

“You will find that some road slabs have been removed or are broken. Some of the roads, especially on the mainland, have no sidewalk where you can run, so you have to dodge vehicles, bikes and even wheelbarrows when trekking or jogging around the area.

“Another issue is the lack of streetlights in some streets. Yes, the best time to jog is at dawn, but when there is no functional streetlight, any crook or hoodlum can hide under the cover of darkness to inflict harm on people jogging.

“Then, some vehicle drivers also violate traffic rules by taking ‘one way,’ so as you are jogging, you are also forced to look behind from time to time to avoid being knocked down by an oncoming vehicle. These things alone made me stop jogging for a while and instead opt for a treadmill.

“There is a need for our roads to be properly managed, our streets well-lit and secured for people to generally embrace early morning jogs.”

Emergencies need to be upgraded – Medical practitioner

However, a medical practitioner, Dr Olaleye Oluwasanmi, pointed out that more still needed to be done for the country’s healthcare to be able to adequately care for people attacked while jogging.

“First, our emergency services should be made accessible to all citizens, upgraded and equipped with necessary facilities that will help in saving lives. There is also a need for first aid and lifesaving kits to be made more accessible to the public.

“This is one of the first differences you will notice in advanced countries. Not only are most citizens well-trained to administer first aid to children or strangers, but there are also lifesaving bleed-control kits installed at strategic places.

“Most importantly, there is a need to curb the brain drain in the medical sector so that the country will stop losing precious lives due to the mass exodus of medical professionals,” Oluwasanmi added.

How the 3-3-3 Rule Helped Me Stick to an Exercise Routine

How the 3-3-3 Rule Helped Me Stick to an Exercise Routine

If you’ve ever started a new workout routine with the best intentions only to find yourself skipping sessions by week two, you’re not alone. I’m the type to get trapped in the same cycle of burnout, where I go hard for a couple of weeks, feel exhausted, feel guilty, and repeat. For me, what finally broke that cycle wasn’t a new gym membership or a fancy fitness app, but a simple scheduling hack: the “3-3-3 rule.” I’d seen this rule applied it to general productivity, and all the same principles can apply to your fitness habits, too. Here’s how you can use the 3-3-3 rules to structure your workouts and create a habit that sticks.

What is the 3-3-3 rule?

The 3-3-3 “rule” (or “method,” or “gentle suggestion”) is essentially a weekly workout framework built around three types of movement, each done three times per week:

  • Three strength training sessions. This includes lifting weights, bodyweight circuits, resistance bands, whatever builds muscle and challenges your body.

  • Three cardio sessions. This includes running, cycling, swimming, jump rope, a dance class—what counts as “cardio” is up for debate, but here, I think of it as anything that gets your heart pumping.

  • Three active recovery days. This includes light walking, yoga, stretching, foam rolling, and so on.

And yes, I realize this math adds up to nine intentional days of movement across a seven-day week. Here’s the thing: You do double duty some days, or skip workouts here and there, or adjust to a nine-day cycle, because the point isn’t rigid scheduling. The point is rhythm over a strict structure. For me, the 3-3-3 rule provides a sense of momentum that’s flexible enough to fit into real life, but consistent enough to actually stick to.

Why the 3-3-3 rule works for me

Before I get into how the 3-3-3 rule helped me specifically, let’s talk about why so many workout plans fall apart in the first place. I believe most of them make two classic mistakes. The first is doing too much, too soon. You go from zero to six days a week at the gym, you get burnt out, and the whole thing unravels. The second mistake is having no real structure at all—just vague intentions, like “I’ll work out when I can,” which never materializes into anything real for a lot of people.

For me, the 3-3-3 rule solves both of those problems. It gives me enough structure to build habit and momentum, but not so much intensity that my body and brain feel overwhelmed. I personally adore running, but I struggle to motivate myself to lift weights; the 3-3-3 rhythm here helped me find a middle ground between those two workouts. When I know I have three strength sessions to hit in a week (or nine-ish day cycle), I can look at my calendar and find three slots without too much drama or dread.

There’s also plenty of breathing room built into the plan, which was the biggest game changer for me. I used to have the (toxic) thought that my rest days were wasted days, which is a mentality that led to either overtraining or complete inactivity with pretty much no middle ground.

Plus, there’s something psychologically satisfying about the number three. I know and love the rule of threes in photography, comedy, survival tips, and all over the place.

How to make a 3-3-3 workout schedule work for you

The 3-3-3 rule has a ton of wiggle room for customization. Here are some ideas for how you can approach it:


What do you think so far?

For strength days, pick a format you actually enjoy. That might be a full-body circuit, a push/pull/legs split, or a class at your gym. (Boxing, anyone?) Your focus on these days should be a progressive challenge—push yourself, yes, but don’t obliterate yourself.

Advertisement

For cardio days, variety helps. Mix a longer, easier effort with a shorter, more intense session (like a 20-minute interval run). I know I’m biased, but cardio really shouldn’t feel like punishment.

For recovery days, resist the urge to “make them count” by sneaking in extra work. The whole point is to let your body consolidate the gains from your harder days. Walk, stretch, breathe, and trust the process.

Another practical tip: Pick a night to map out your 3-3-3 week ahead of time. You’ll probably find that the week arranges itself pretty naturally once you’re looking for those nine windows.

The bottom line

As always, consistency should always be your priority in fitness. If you’ve been struggling to find a rhythm, if your past workout plans have always fizzled out around week three, give the 3-3-3 rule an honest four-week try. Maybe start with a 1-1-1 month! After all, the 3-3-3 rule isn’t a hack to totally transform your physique, but I do think it can provide something way more valuable. Finding a routine that works for you—like the 3-3-3 rule works for me—is the first step to make exercise a reliable, sustainable part of your life.

QLVR ENDVR: Two minute review

Most running shoes feel familiar for a reason: the formula has barely changed in millennia. We have archaeological evidence of shoes being fastened with “shoelaces” as far back as around 3,500 BC, yet the basic lace-up running trainer remains the default.

QLVR (pronounced “clever”) set out to challenge that. Its debut shoe, the ENDVR, is a laceless “running slipper” built around a women-specific mechanical structure, with a slip-on Wing Fit system inspired by the way a bird’s wing opens and closes around movement.

Mere minutes of daily vigorous exercise can cut your risk of 8 diseases | CNN

Mere minutes of daily vigorous exercise can cut your risk of 8 diseases | CNN

Move more. Sit less. For many years, that’s been accepted guidance for people wanting to get healthier.

Now that message is getting refined, with a growing body of research suggesting that certain types of movements may be more beneficial than others when it comes to health benefits.

The intensity of your exercise may matter as well. A new study published in the European Heart Journal found that a small amount of vigorous activity may be linked to lower risk of eight different chronic diseases.

The findings raise questions about why intensity matters and how people can incorporate more intense exercise routines into everyday life. To better understand the study’s implications, I spoke with CNN wellness expert Dr. Leana Wen, an emergency physician and clinical associate professor at George Washington University. She previously served as Baltimore’s health commissioner.

Before beginning any new exercise program, consult your doctor. Stop immediately if you experience pain.

CNN: What did this study examine about exercise and its relationship to chronic disease?

Dr. Leana Wen: This investigation looked at how the intensity of physical activity is related to the risk of developing a range of chronic diseases. Researchers analyzed data from two very large groups in the UK Biobank, which is a long-term health study in the United Kingdom that tracks medical and lifestyle information from hundreds of thousands of participants. One group included about 96,000 people who wore wrist activity trackers that objectively measured their movement, and the other included more than 375,000 people who self-reported their activity.

The researchers followed participants over an average of about nine years and examined the development of eight conditions: major cardiovascular events, atrial fibrillation, type 2 diabetes, immune-related inflammatory diseases, fatty liver disease, chronic respiratory disease, chronic kidney disease and dementia, as well as overall mortality.

The key finding was that the proportion of activity done at vigorous intensity mattered. People who had more than about 4% of their total activity classified as vigorous had substantially lower risks of developing these conditions compared with people who had no vigorous activity at all. The numbers were stunning, with the participants having the following results:


  • 63% lower risk of dementia,

  • 60% lower risk of type 2 diabetes,

  • 48% lower risk of fatty liver disease,

  • 44% lower risk of chronic respiratory disease,

  • 41% lower risk of chronic kidney disease,

  • 39% lower risk of immune-mediated inflammatory diseases,

  • 31% lower risk of major cardiovascular events,

  • 29% lower risk of atrial fibrillation, and

  • 46% lower risk of death from any cause.

These results are amazing. Imagine if someone invented a medication that could reduce the risks of all these diseases at once — it would be very popular! Crucially, even people who exercised a lot still benefited if the proportion of time they spent doing vigorous physical activity was increased. Conversely, people who were relatively inactive also benefited from adding just a little bit of higher-intensity exercise to their daily routines.

CNN: What counts as “vigorous” physical activity?

Advertisement

Wen: Vigorous activity is generally defined as exercise that substantially raises your heart rate and breathing. A simple way to gauge it is the “talk test.” If you can speak comfortably in full sentences while exercising, you are likely in the low to moderate range. If you are so out of breath that you can only say a few words at a time, that is vigorous.

Running, cycling, lap swimming or climbing stairs quickly could count. But this also depends on people’s baseline fitness. For some individuals, taking longer strides with walking can be vigorous exercise. Others who are already fairly fit would need to do more. It’s also important to remember that vigorous activity doesn’t have to be in the context of a structured exercise plan. Short bursts of effort in daily life, such as rushing to catch a bus or carrying heavy groceries upstairs, can also qualify if they raise your heart rate and make you breathless.

CNN: Why might higher intensity exercise provide additional health benefits?

Wen: Higher intensity activity places greater demands on the body in a shorter period. This type of movement can improve cardiovascular fitness, increase insulin sensitivity and support metabolic health more efficiently than lower-intensity activity alone. Some studies have also linked vigorous activity with cognitive benefits.

Greater intensity may have distinct benefits across different organ systems. The researchers found that some conditions, such as immune-mediated inflammatory diseases, appeared to be more strongly linked to the intensity of activity than to the total amount. On the other hand, type 2 diabetes and kidney disease were influenced by both how much activity people did and how intense it was. Why this is the case is not yet known, but intensity appears to have a significant impact across diseases affecting multiple organs.

Advertisement

CNN: How much vigorous activity do people need?

Wen: The threshold for people seeing a benefit appears to be relatively low. The researchers found that once people reached more than about 4% of their total activity as vigorous, their risk of developing chronic diseases dropped substantially.

To put that into practical terms, we are not talking about professional athletes dedicating their lives to hours of high-intensity training. Everyday people may see benefits from just doing a few minutes of vigorous effort daily.

CNN: How can people realistically incorporate vigorous activity into their daily routines?

Wen: One helpful way to think practically is that vigorous activity does not have to happen all at once. It can be accumulated in short bursts throughout the day.

People can take the stairs instead of the elevator and do so at a faster pace than usual. When they are heading to work, they can add some speed walking. They can park farther away when grocery shopping and walk briskly while carrying groceries.

Structured exercise also can incorporate intervals where people alternate between moderate and more intense effort. If you’re swimming laps, you can warm up at a more leisurely pace, then do a few laps at a faster pace, then again at a leisurely pace and repeat. This suggestion applies to any other aerobic exercise: Aim for multiple intervals of at least 30 seconds to a minute each where your body is working hard enough that you feel noticeably out of breath.

CNN: What about someone who is older or has mobility issues?

Wen: Not everyone can or should engage in high-intensity activity in the same way. Vigorous activity is relative to that person’s baseline. For someone who is not used to exercise, even a short period of slightly faster walking or standing up repeatedly from a chair could be considered high intensity. And not everyone may be able to walk. In that case, some exercises from the chair can have aerobic benefits.

Individuals who have specific medical conditions should consult with their primary care clinicians before embarking on a new exercise routine. People with mobility issues also may benefit from working with a physical therapist who can help to tailor exercises appropriate to their specific situation.

CNN: What is the key takeaway for people trying to improve their health?

Wen: To me, the main takeaway from this study is that it’s not only how much total exercise you get but also how hard you push yourself that matters. And you don’t have to have a lot of high-intensity exercise: Adding just a little has substantial health benefits across a wide range of chronic health conditions.

At the same time, exercise needs be practical. People should look for opportunities to safely increase intensity in ways that fit their daily lives. The most effective approach to physical activity is a balanced one: Exercise regularly, incorporate more challenging activities when you can and build habits that are sustainable over time.
