Least fit people need to do more exercise than fittest to get same benefit – study
People who are the least fit need to do 30-50 minutes more exercise a week than the fittest to get the same reduction in cardiovascular risk, according to research.
Researchers examined data from more than 17,000 British adults taking part in the UK Biobank study. They completed a cycle test to measure their baseline cardiorespiratory fitness (estimated VO2 max) and wore a fitness tracker for a week to record typical exercise levels.
The adults, aged 40-69 were tracked for an average of eight years, during which there were more than 1,200 cardiovascular incidents, including heart attack, atrial fibrillation stroke and heart failure.
The NHS advises adults to do at least 150 minutes of moderate to vigorous physical activity each week, such as brisk walking, cycling or running.
The study, published in the British Journal of Sports Medicine, found achieving this guideline of two and a half hours’ exercise was associated with a 8-9% reduced cardiovascular risk.
“Given that large proportions of the population do not meet even this benchmark, the primary public health message remains straightforward: achieving 150 minutes per week of moderate to vigorous activity delivers meaningful cardiovascular protection regardless of fitness level,” the authors conclude.
The research also calculates that more exercise lowered the risk even further, but that those with the lowest fitness needed about 30-50 extra minutes’ exercise a week to obtain the same benefits.
To achieve a 20% reduced risk, the least fit needed to do 370 minutes of moderate to vigorous physical activity a week, whereas those with the highest fitness levels only needed 340 minutes.
To reduce the odds of cardiovascular events by more than 30%, the least fit would need to do more than 10 hours (610 minutes) while the most fit would have to do just over nine hours (560 minutes).
“This finding highlights the steeper challenge faced by deconditioned populations,” the research concludes.
“Current moderate-to-vigorous physical activity guidelines provide a universal but modest safety margin, whereas optimal cardiovascular protection may require substantially higher activity volumes.”
“Future guidelines and implementation strategies may need to differentiate between the minimal moderate-to-vigorous physical activity volume required for a basic safety margin and the substantially higher volumes necessary for optimal cardiovascular risk reduction.”
The findings appear to challenge previous research, which found that walking only 4,000 steps a day would still reduce older people’s risk of dying early by around a quarter.
But experts said recommending more than nine hours a week of exercise was “misguided”.
Aiden Doherty, professor of biomedical informatics at the University of Oxford, said: “We can’t give much weight to the figure of 560-610 minutes of exercise a week.
“Clearly there will be cardiovascular benefit for people who are able to do (more than) 1 hour 20 minutes of moderate-to-vigorous intensity physical activity a day but this is not a sensible public health message.
“The public should continue to aim for at least 150 minutes of moderate to vigorous intensity of physical activity a week; more is better; every move counts.”
Responding to the findings, a Sport England spokesperson said that increasing activity levels was vital for keeping people healthier for longer: “Emerging research like this reinforces the importance of helping more people be active, more often.
“Sport England’s own research shows activity relieves healthcare issues for both individuals and the NHS, preventing 1.3 million cases of depression, 600,000 of diabetes and 57,000 of dementia.”

Social Fitness: Why Independent Living Communities Are Vital for Healthy Aging

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.
