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.”

The bridge variation women over 40 need to build deep core strength – without a single crunch

The bridge variation women over 40 need to build deep core strength – without a single crunch

Building a stronger core is important at any age, but particularly once you wave goodbye to your 30s. Research shows muscle mass decreases approximately 3-8% per decade after this age, with the rate of loss increasing further after 60, and because having a strong core is so important to overall mobility, it’s an area of the body you don’t want to neglect.

Luckily, strength and fat loss coach Silvana Catalano has shared the ab exercise she credits with helping her build a stronger core after 40.

‘I stopped doing crunches and started doing this foam roller bridge variation instead,’ she said. ‘[It works] better than any crunch.’

Explaining why she moved away from the traditional ab exercise, Catalano said that ‘crunches flex [bend] your spine repeatedly under load’.

‘After 40, this can cause neck strain, back pain and only targets your surface muscles — not your deep core muscles,’ she added.

How to do the foam roller single-leg bridge with leg extension

  • Lie on your back with both heels on a foam roller, knees bent, and arms by your sides.
  • Press through your heels to lift your hips into a bridge, creating a straight line from your shoulders to your knees.
  • Keeping your hips elevated and level, extend one leg straight up toward the ceiling.
  • Hold briefly, maintaining control and avoiding any hip drop or rotation.
  • Lower the extended leg back to the starting position with control.
  • Repeat on the opposite side while keeping your hips elevated throughout.

Perform 3 sets of 10-12 reps each side.

You can progressively overload the exercise every week, or increase the difficulty, in a few ways, including:

  • Adding extra sets or reps
  • Holding the bridge position for longer
  • Adding weight by placing a dumbbell or weight plate across your hips or a resistance band around your thighs

Why it works

‘The foam roller is the game changer,’ says Catalano. ‘It creates instability that forces your deep core to work overtime to stabilise your entire body.’

Your transverse abdominis — the deep core muscle that wraps around your waist like a corset — fires throughout the entire movement.

She added that this is the muscle which can help to make your stomach appear flatter.

‘Not your surface abs or your rectus abdominis [your ‘six pack’ muscles] but the deep muscles underneath’,’ she concluded.

Combining the foam roller bridge with the single leg extension engages your glutes, hamstrings, core and hip flexors simultaneously, improving lower-body strength and control.

Strength training over decades linked to longer life – Harvard Health

Strength training over decades linked to longer life – Harvard Health


We’ve long known that aerobic exercise might help us live longer, and now strength training is being credited with the same effect. People who do up to two hours of strength training each week, over several decades, may reduce their risk of dying earlier from several serious conditions, including heart disease and neurological diseases, according to a Harvard-led study published June 12, 2026, in the British Journal of Sports Medicine.

Researchers analyzed three major studies involving 147,374 adults (79% women) who were middle-aged or older at the study’s start and tracked for up to 30 years. Participants reported how frequently and vigorously they exercised, including resistance training (which can include weight lifting and body-weight movements) and aerobic activity (such as brisk walking, cycling, and running). Deaths from all causes were also recorded.

Participants who logged between 90 and 119 minutes of resistance training each week were 13% less likely to die during the study period from any cause compared with those who did no strength training. They also had a 19% lower risk of dying from cardiovascular disease and a 27% lower risk of dying from neurological diseases such as dementia. Aerobic exercise remained a strong, independent predictor of living longer, but the greatest benefit was observed when resistance training was combined with it. Participants who regularly did both had up to a 45% lower risk of dying during the study period than those who did little aerobic activity and no resistance training.

If you don’t already engage in strength training, it may be wise to start. Begin with body-weight exercises such as squats, push-ups, or step-ups on a low stair. Add resistance bands or light dumbbells to increase the benefits. Consider enlisting the guidance of a physical therapist or personal trainer, and aim for consistency over time.

‘This works’: Fitness icon Suzy Jalowsky, 60, shares the simple exercise formula she swears by

It’s easy to overcomplicate your fitness routine, especially when you’re being bombarded by information on social media about how to optimise every aspect of your workouts. But improving your fitness and building strength doesn’t have to be complicated – as a new reel from fitness icon Suzi Jalowsky shows.

The 60-year-old shared how just 30 minutes of walking daily paired with three simple strength workouts can help women over 40 ‘look better, feel better and stay strong’ as they age.

‘This works,’ she wrote in the caption. ‘Consistency with the basics will take you where you want to be. We often look for complicated solutions, but the basics are what truly change your body.’

Suzi Jalowsky’s strength routine

To add to the simplicity of the workout, Jalowsky uses just two 12lb (roughly 5kg) dumbbells throughout – so you don’t need to spend hundreds of pounds on expensive equipment to get started.

The workout

How to do the moves

  • Stand with your feet hip-width apart and a slight bend in your knees.
  • Hinge at your hips until your chest is almost parallel to the floor, keeping your back flat and your shoulders down.
  • Hold a dumbbell in each hand with your palms facing each other and your arms hanging below your shoulders.
  • With a slight bend in your elbows, raise the weights out to shoulder height, squeezing your upper back and shoulder blades together.
  • Lower the dumbbells back to the starting position with control.

  • Stand with your feet shoulder-width apart, holding a dumbbell in each hand.
  • Bend over while bracing your core and keeping your back straight and chin tucked.
  • Draw the dumbbells towards your waist, keeping the elbow tucked into your side.
  • To complete the rep, extend the arms back to the starting position.

  • Stand with your feet hip-width apart, hands on your hips.
  • Take a big step back with your right leg, crossing it behind your left. Bend your knees and lower your hips until your left thigh is nearly parallel to the floor. Keep your torso upright and your hips and shoulders as square as possible to the wall in front of you.
  • Return to start. Then repeat on the other side.

  • Start with a dumbbell in each hand, arms down and palms facing your body.
  • Rotate each hand so your palms face forwards. Keeping a slight bend in the knees, activate your glutes.
  • Engaging your core to avoid any sway in the hips, bend your arms, lifting one of weights to chest height in a slow, controlled movement.
  • Keep your shoulders relaxed and down, and keep your head, neck and spine neutral. Don’t arch your back.
  • In another slow, controlled movement, lower the weight back down to your thighs by straightening your arms while raising the other one to your chest. Repeat.

  • Stand with your knees bent and lean forward slightly, with a dumbbell in each hand.
  • Keeping your back straight, bend your dumbell-holding arm 90 degrees at the elbow so your triceps are aligned with your back and your biceps are perpendicular to the floor.
  • Engage your core and your triceps and hinge at the elbow, lifting the dumbbell up and back as you try and straighten your arm. Your triceps should stay still; only your elbow moves.
  • Guide the weight upward until your arm is straight, pause, then lower back down slightly to begin your pulses.

  • Stand with your feet slightly wider than shoulder width apart, evenly distribute your weight, and turn your toes out to 10 and 2 o’clock. Hold a dumbbell in each hand.
  • Keep your core tight and chest tall as you inhale, bend your knees, and sink your hips down until your thighs are parallel to the floor.
  • Exhale as you drive through your feet back to an upright standing position.

  • Stand with your feet shoulder-width apart, holding the dumbbells with straight arms in front of your legs. Your palms should face your body.
  • Engage your abs. Keep your chest up and eyes forward.
  • Lift the dumbbells up to mid-chest height or just below your chin. Keep your dumbbells close to your body by raising your elbows up and out to the sides.
  • Pause at the top, then lower with control to the beginning.

  • Stand with your feet hip-width apart, holding a dumbbell in each hand.
  • Bend your elbows to 90 degrees, tucking them tightly against your waist with your palms facing upwards.
  • Slowly extend your arms out in front, raising them to shoulder height.
  • Pull your elbows pack to the starting position.

  • Start with your feet together, holding a dumbbell in both hands at your sides. Shift your weight to your left leg, with your knee slightly bent.
  • Hinge at your hips to bring your chest down while raising your right leg behind you until your body is in a line from your head to your right foot.
  • Reverse back to the starting position and repeat, then switch sides.

Star jump with squat

  • Start by standing with your feet shoulder-width apart and a single dumbbell held with both your hands in front of your chest.
  • In one movement, jump your feet out to the side and press the dumbbell over your head.
  • Jump your feet back in, bring the dumbbell back to your chest and lower into a squat. Continue by jumping your feet out to the side again and repeating the movement.
