Fitness face-off – Harvard Health
What’s in style? The question doesn’t just relate to fashion. Indeed, even exercise styles go in and out of vogue, echoing trends fueled by social media and other cultural drivers.
Case in point: high-intensity bursts of exercise have grabbed headlines over the past couple of years, with scientists generating an array of studies examining the health benefits of short spurts of movement lasting from one to three minutes. That might consist of jumping jacks, lunges, running in place, jumping rope, air boxing, running up stairs, or any other high-intensity activity.
Meanwhile, plenty of research continues to focus on the health advantages of moderate-intensity, continuous movement. Mainstay choices for these sessions include brisk walking, cycling, jogging, and elliptical and treadmill use.
Given the swings in popularity between the differently paced alternatives, perhaps the most pressing question is which one is better for us. It might seem certain exercise patterns might prove superior to others, but we should resist the temptation to believe that, says Dr. Meagan Wasfy, a sports cardiologist at Harvard-affiliated Massachusetts General Hospital.
“There are always trends, and each one claims to be the latest and best way to move your body,” Dr. Wasfy says.
Breaking down the data
What health benefits does each approach offer? A sampling of recent studies and official health guidance weighs in.
Evidence supporting exercise bursts includes the following:
- A 2022 analysis of data collected on more than 25,200 people who didn’t otherwise exercise (average age 62, 56% women) published in Nature Medicine found that those who routinely did brief bursts of vigorous activity — defined as three bouts, each lasting a minute or two — had significantly lower odds of dying or developing cardiovascular disease over the following seven years than participants who didn’t.
- A 2023 analysis in JAMA Oncology of more than 22,000 people who didn’t exercise (average age 62, 55% women) suggested that even short, intermittent periods of intense movement — a minute at a time, three or four times a day — was linked with 18% lower cancer risk over the following 6.7 years, especially for cancers of the breast, uterus, or colon.
Evidence supporting longer, moderate-intensity exercise includes the following:
- Adults who do any amount of moderate-to-vigorous exercise derive health benefits, including reducing their risks of cardiovascular disease, diabetes, and some forms of cancer, according to the CDC.
- A 2022 analysis in JAMA Internal Medicine involving 78,000 people (average age 61, 55% women) found their risk of heart disease, cancer, and premature death dropped by 10% over the following seven years for every 2,000 steps they logged each day, with the benefit peaking at 10,000 steps.
Sense a theme from the findings? Regardless of intensity, it’s apparent that any movement is good for your health.
“No one comes out ahead with regards to the long-term outcomes,” Dr. Wasfy says. “What matters most is moving your body and doing more of it. The sum of movement, over the course of a year or decades of your life, is what matters.”
Exercise caveats
One clear advantage to exercise bursts — or its cousin, high-intensity interval training (HIIT) — is that any high-intensity activity enables you to fulfill recommended exercise guidelines in less time. Health organizations advise adults to get at least 150 minutes of moderate exercise or 75 minutes of vigorous exercise (or some equivalent combination of the two) per week. For an HIIT workout, you alternate vigorous, short sprints with brief periods of rest or lower-intensity movement.
“It’s a time-efficient way to get your recommended exercise dose in less time,” Dr. Wasfy says.
High-intensity exercise does pose a few drawbacks, however. These include a greater risk of injuries and inflammation to joints and muscles. Additionally, for people with heart disease or its risk factors, sudden bursts of exercise could be more likely to bring on new cardiac symptoms.
“If you’re writing an exercise prescription not knowing anything about someone’s health history, you’d write it for moderate-intensity, continuous exercise,” Dr. Wasfy says.
If you’d like to increase your exercise intensity but have existing heart disease — or symptoms such as chest pain with vigorous movement — talk to your doctor in advance. Older adults who’ve noticed their ability to exercise has declined should also speak up.
Ultimately, Dr. Wasfy says, you should choose a style of exercise you really like — and will do consistently — and disregard fitness trends. “If you’re healthy,” she says, “it’s really your choice.”

Alexandra Daddario, 40, relies on this underrated crunch upgrade for strong abs – here’s how to do it properly
From enduring some serious physical prep for Baywatch to working consistently with elite trainer Patrick Murphy, Alexanda Daddario’s dedication to fitness is well-documented. She often shares insights on social media, and in a recent Instagram post, the White Lotus star gave an insight into how she trains her core with one powerhouse movement: the reverse crunch into shoulder stand.
Why is it so good? Most traditional ab exercises require repetitive spinal flexion – the process of pulling your chest down toward your knees, like in a standard crunch. This isolates only the upper section of your abs, and for women who spend hours sitting at a desk, it can reinforce a slouched, rounded posture.
Daddario’s movement flips the mechanics entirely since you actively curl your pelvis up toward your chest. In doing so, you target not only your upper abs, but the lower portion and your obliques (the sides) simultaneously, all while keeping your chest open and your neck unstrained. This translates into a much stronger core, better posture and crucial lower back protection. Research also shows that a controlled posterior tilt – the lower-body curl that initiates Daddario’s move – recruits a significantly higher percentage of deep core muscle fibres than traditional crunches.
Daddario then drives her hips directly up into a vertical shoulder stand. This completely removes momentum from the equation (meaning you can’t “cheat”) and forces your abs – particularly your obliques – to balance your body and prevent you from tipping sideways.
She then takes it one step further into a Pilates plow position with her legs overhead, before reversing the movement and, again, using her abs to control the lowering of her entire lower body as she slowly unrolls her spine down onto the mat. The plow portion is optional (and super advanced); the slow, controlled, lowering phase, which happens whether you move into plow or not, is where the magic happens, challenging your core through both lifting and resisting gravity. Inspired? Here’s exactly how to do the move with good form, and how many reps and sets to aim for.
How to do a reverse crunch into shoulder stand
- Lie on your back (either on a mat, or on a reformer Pilates machine, like Daddario, with your arms anchored tightly to the floor.
- Engage your core to curl your knees toward your chest, then fluidly press your feet straight up toward the ceiling, lifting your hips and lower back off the floor.
- Slowly lower down, one vertebra at a time. Aim for 3 sets of 6-8 controlled reps.
Optional progression:
- As you reach shoulder stand with your legs extended to the ceiling, slowly start to lower your toes toward the floor over your head. Your weight should rest entirely on your shoulders and upper back – not your neck.
- Keeping your legs straight, use your core to extend them straight back up to the ceiling, then control the descent by rolling your spine down one vertebra at a time, with your legs remaining straight.

Built Strong: Fitness forges unbreakable father-son bond
Fathers often share special bonds with their children. For 80-year-old Chanka Ramrattan, that bond is a shared love for fitness and exercise with his 46-year-old son Nari.
The Rousillac resident recalled that he began exercising at the age of 14, lifting weights and taking long walks, a passion that remains with him today. During his time working as a clerk at Texaco, he said he would walk from Forest Reserve to his Rousillac home, a distance of approximately 12 kilometres.
“I have done every marathon in Trinidad; you name a marathon, I could tell you. Miami Marathon, Tobago Sea-to-Sea, which is the most difficult marathon that I’ve ever done. I even have a trophy where I got the fastest speed walking man, and I have all my medals,” he recounted.
Chanka’s last marathon was a virtual one in 2021. Since then, his doctor has advised him to slow down because of his age. Now, he spends his time at the Health and Fitness Gym in Debe and South Oropouche about three times a week, walking marathons of his own on the treadmill.
“I do cardio walking for one hour, and I do weight training for one hour. Then, I go in the sea and I swim and dive for one hour,” he noted.
Chanka firmly believes regular exercise has contributed to his longevity and said he plans to keep going.
“Exercise is very important, and I like exercise. You go to Miami, and you’ll see 90-year-olds and 100-year-olds in the gym, walking, and even going to marathons. That’s because if you don’t exercise, you feel lethargic, you feel down. And you also have to read a lot. So, you exercise the brain, and you exercise the body,” Chanka advised.
His son Nari believes that perseverance was one of the most important lessons his father passed on to his children, along with a love of fitness and exercise.
“When you are looking at your dad, and your mom, and you are seeing them exercising and you are seeing them fit, why would you not want to do the same thing? So, it was instilled in all of us, myself and my two siblings. That exercising became a routine. My bigger sister, she would run, and my smaller sister would do cardio,” Nari explained.
The engineer and businessman recalled starting to exercise and lift weights with his father and uncle from a young age, crediting the experience with shaping the discipline and fitness mindset he still follows today.
However, in 2016, he faced a big obstacle after he hit his head during a diving accident, damaging his C6 and C7 vertebrae and spinal cord.
“I was 37 at the time when I got into the accident. I lost all feeling in my body. The person that you see in front of you now is not the person I was three years ago. I actually couldn’t move at all; I could only move my toe. It took a lot of hard work and will, to come out of that situation. Eventually, I started to transfer from my wheelchair to a bed, to a car. I even built a machine for me to stand up with a harness, and it pulls me up in the air so I can stand up straight. So, I used that for two years to get my body back to where it is,” Nari explained.
Nari, who is currently a quadriplegic, said he was only able to make progress through persistence and support from his loved ones. Chanka admitted that period was one of the most difficult experiences of his life as a parent.
“I wouldn’t like to explain that, that is a different thing altogether. He was in Mount Hope for six months, we had to go every day. It was a real trying thing, but you know, he is on the way to recovery. His mother wants to see everything good for him. For me, she will treat me second class and she will treat them first class, and she is right. Because the ones that are able to walk, you give them less attention because they are tending to themselves. You have to give more attention to the one that needs attention,” he acknowledged.
But their bond through exercising didn’t change. During COVID-19, Nari said his father returned to weightlifting under his son’s guidance.
“When my dad was trapped in the house and he couldn’t go anywhere, he was very miserable. So, we had a schedule where he and I would use the weights that I have at home, and I would tell him what to do. He actually got a six-pack during COVID. So, we stayed home and exercised with my wife and all too. After, I realised now I could start back to go to gym,” Nari reflected.
Chanka said his son’s determination continues to inspire him.
“When you see somebody who is a bit incapacitated and they’re exercising, they give you inspiration. Like if that man could do that, I could do that too. I wish Nari all the best. He is adhering to all his exercises, and he has a will that you won’t get in your next life. It’s probably my genes passed on to him,” Chanka shared.
Nari said none of that would have been possible without his father’s influence.
“Dad, I just want to tell you, thank you very much for being in our lives. You give us the encouragement to go day to day, and just keep being who you are, because you have a strong will, strong mind, and that is what keeps us going every day,” he said.

Angela Rippon, 81, reveals the one exercise she never skips for strong legs: ‘I do it every morning without fail’
At 81, Angela Rippon is one of the UK’s most energetic and active broadcasters. A long-time advocate for movement, the former ballet dancer has often credited simple, consistent habits with helping her stay strong, mobile and independent as she gets older. And among her daily rituals is one surprisingly simple exercise she swears by: pliés.
‘I’ll do 20 pliés in the morning, because that’s really good for your balance, your knees, your posture, your core strength, for everything,’ she told Good Housekeeping. ‘Ballet is a wonderful thing for keeping your legs in good shape. It builds the right muscles in your calves and thigh. I go to class whenever I can. I’m a great advocate for dance being the best form of exercise for your mind and your body.’
Pliés are an easy move that require no equipment and Rippon’s 20 reps take less than a minute to do, yet experts agree that they can offer a host of benefits, from improving balance and posture to building lower-body strength and supporting healthy joints. As Women’s Health Fashion Editor and dance instructor Isabelle Knevett says, ‘Plies strengthen the legs, glutes and inner thighs simultaneously. They also require core activation in order to maintain an upright posture, which helps train your balance and stability.’
Research backs Rippon’s morning habit, too. A 2024 study found that a 10-week classical ballet programme improved lower-body strength and physical function in women over 50, suggesting ballet-inspired movements may help support mobility and independence as we age.
And Angela has one more non-negotiable within her morning routine: stretching. ‘I do it every day without fail. Even if I’m on a really tight schedule and in a very small hotel room. Think about a cat. A cat might sleep for five hours, but when they get up, they stretch absolutely everything. I feel that after I’ve been sleeping, that’s what I need to do to get everything moving again.’
As for its benefits for longevity, a recent study published in the Scandinavian Journal of Medicine & Science in Sports found that greater flexibility was associated with a lower risk of early death, while other research found that a 10-minute at-home stretching routine can counteract significant decreases in strength, flexibility and jumping performance caused by low physical activity levels. Consider us influenced.
