Substantial heart health benefits may require 560-610 minutes of weekly exercise, with lower fitness individuals needing even more activity to achieve similar protection.

Adults may need far more exercise than current public health guidelines recommend to significantly lower their risk of heart attack and stroke, according to an observational study published online in the British Journal of Sports Medicine.

Researchers found that adults needed between 560 and 610 minutes of moderate to vigorous physical activity each week for a substantial reduction in cardiovascular risk. That is roughly 3 to 4 times higher than the current recommendation of at least 150 minutes weekly of activities such as brisk walking, running, or cycling.

The findings also suggest that people with lower fitness levels need slightly more exercise than highly fit individuals to achieve the same cardiovascular benefits.

Researchers said current exercise recommendations may need to move away from a one-size-fits-all approach and instead provide personalized goals based on a person’s fitness level.

VO2 Max and Cardiovascular Fitness Explained

Cardiorespiratory fitness differs widely between individuals and is considered a strong indicator of heart health. Researchers noted that low cardiorespiratory fitness is closely linked to a higher risk of heart attacks, strokes, and early death.

One common way to measure fitness is through VO2 max, which reflects the maximum amount of oxygen the body can use during intense exercise. The measurement shows how efficiently the heart, lungs, and muscles work together to deliver and use oxygen.

Researchers from Macao Polytechnic University in China investigated how physical activity levels and cardiorespiratory fitness, measured through VO2 max, influenced cardiovascular disease risk.

UK Biobank Study Tracks Exercise and Heart Events

The study analyzed data from 17,088 participants in the UK Biobank study collected between 2013 and 2015. Participants had an average age of 57, while 56% were women and 96% were white.

Participants wore wrist devices for seven consecutive days to track their normal exercise levels. They also completed a cycling test to estimate VO2 max.

The researchers included additional information such as smoking habits, alcohol use, self reported health and diet, body mass index, resting heart rate, and blood pressure.

Over an average follow-up period of 7.8 years, researchers recorded 1,233 cardiovascular events. These included 874 cases of atrial fibrillation, 156 heart attacks, 111 cases of heart failure, and 92 strokes.

560–610 Minutes Weekly Linked to Stronger Risk Reduction

Adults who met the current guideline of 150 minutes of exercise per week saw a modest 8% to 9% reduction in cardiovascular risk, regardless of fitness level.

However, achieving a more substantial reduction of greater than 30% required between 560 and 610 minutes of moderate to vigorous exercise weekly. Only 12% of participants reached that level of activity.

Lower Fitness Levels Require More Physical Activity

The analysis showed that participants with the lowest fitness levels needed about 30 to 50 additional minutes of exercise each week compared with highly fit individuals to gain similar benefits.

For example, a person with low fitness needed about 370 minutes of moderate to vigorous exercise each week to reduce cardiovascular risk by 20%, compared with 340 minutes for someone with high fitness.

The researchers say, “This finding highlights the steeper challenge faced by deconditioned populations.”

Researchers Call for Personalized Exercise Guidelines

Because the study was observational, the researchers said it cannot prove cause and effect. They also acknowledged that participants may have been healthier and fitter than the general population. Additional limitations included estimating cardiorespiratory fitness rather than directly measuring it and not tracking sedentary behavior or lighter physical activity.

The team said the findings support current exercise guidelines as an effective minimum target for cardiovascular protection. However, they added that more personalized recommendations could help motivated individuals further reduce their heart disease risk.

“Future guidelines may need to differentiate between the minimal moderate to vigorous exercise volume required for a basic safety margin and the substantially higher volumes necessary for optimal cardiovascular risk reduction,” they conclude.

Alison Hammond lost 11st and transformed her health by quitting these 3 habits – here’s how

Alison Hammond lost 11st and transformed her health by quitting these 3 habits – here’s how

Exercise played a pivotal part in Alison Hammond, 51, losing 11 stone. The This Morning presenter hired personal trainer Ellis Gatfield five years ago, and while introducing regular strength training helped her hit her goal, there were a few fitness habits she was also required to quit.

Below, Gatfield shares exactly what she stopped doing, how doing so helped her lose weight and build muscle and her full weekly workout routine.

A quick caveat: sustainable weight loss isn’t driven by exercise or nutrition alone. Movement helps preserve muscle, support metabolic health and improve how your body uses energy, but what you eat still matters. The most effective approach combines smart training with nourishing, realistic nutrition habits you can maintain long term.

1. She stopped doing long treadmill sessions

Gatfield says: ‘She never particularly enjoyed traditional cardio, so instead of forcing long treadmill sessions, I focused on raising her heart rate through resistance training performed in a circuit format, using mainly compound movements. This allowed her to get the cardiovascular benefits while also building strength and shaping her body. The biggest mistake from her training before was believing that exercise had to mean long, boring cardio sessions to lose weight. That mindset made training feel like a chore rather than something to enjoy.’

2. She stopped forcing exercise she didn’t enjoy

Gatfield says: ‘Once we shifted to a style of training she genuinely liked, everything became easier. Training stopped feeling forced, consistency improved naturally, and results followed. Enjoyment is often the missing piece in successful weight loss and it’s something I prioritise with all my clients.

‘Strength training played a huge role in Alison’s weight loss because it allowed her to burn calories, build lean muscle, and improve her metabolism, without relying on long or exhausting cardio sessions. Resistance-based circuits kept her heart rate elevated while also improving strength and body composition which is key for long term fat loss.

‘Just as importantly, she genuinely enjoyed this style of training. She loved being able to come in, work hard for 30 minutes, feel accomplished, and get on with her day. That enjoyment made consistency easy, and consistency is where results come from.

‘With Alison, the priority was keeping training effective, enjoyable, and realistic around her schedule. Sessions were always kept to around 30 minutes, which meant they were easy to commit to and never felt overwhelming.’

3. She stopped skipping rest days

Gatfield says: ‘Rest was equally essential [to her results]. Scheduled recovery days helped regulate stress, reduce fatigue, and allow her body to adapt and improve. That balance between training and recovery meant she could show up strong, train with intent, and sustain results long term.

‘For most women, especially those new to resistance training, I’d recommend two-three sessions per week. The focus should always be on learning proper technique, moving well, and recovering properly. More isn’t always better – consistency and quality matter far more.’

Alison Hammond’s weekly workout schedule

According to Gatfield, a typical week in workouts for Alison included:

  • Monday: 30-minute resistance circuit
  • Tuesday: 30-minute boxing session
  • Wednesday: rest or low-intensity walk
  • Thursday: 30-minute kettlebell circuit
  • Friday: 30-minute boxing session
  • Saturday: rest or low-intensity walk
  • Sunday: rest

Gary Neville’s 5-Day-a-Week Fitness Routine – and How Exercise Changed His Life After Football

Gary Neville’s 5-Day-a-Week Fitness Routine – and How Exercise Changed His Life After Football

If there’s one man who could do with a rest, it’s Gary Neville. But in between managing his media and business interests, the former footballer still starts most weekdays the same way: waking up early for a 6am workout.

‘My whole life has been about routine and repetition,’ Neville told The Times. ‘Even now, I need structure in every part of my life.

‘I’m up every morning at quarter past five. I’ll have a coffee, review all the news – sports news mainly, but news as well. All your papers, so I’m across everything. Five mornings a week I’ll then walk to the gym for six, and finish at 6:50 before walking back home for seven.’

The 51-year-old favours high-intensity, circuit-style training rather than traditional bodybuilding workouts, having regularly attended Barry’s classes over the years. That said, strength work still forms part of his routine.

It’s an approach Neville adopted after learning a difficult lesson in retirement. Having stepped away from professional football in 2011, he admits he spent the first couple of years enjoying himself a little too much.

The Wake-Up Call That Changed Gary Neville’s Fitness

‘The impact of not training every day surprised me,’ Neville said in a social media video.

‘I think I took for granted how training made me feel good about myself – in my body, in my head. And then when I finished playing football, I started to have a glass of wine at night regularly, I started to have a bit of cheese, I started to have more chocolate.

‘I started to think I could just relax and enjoy my life from a nutrition and fitness point of view. I didn’t work very hard at all – in fact I didn’t train much in the first year or two [after retirement].’

The weight gain that followed eventually prompted an intervention from his wife.

‘If you look at those first couple of years outside of football, you’ll see that I put weight on,’ he said.

‘I remember my wife coming up to me one day and saying, “Look, come on, you need to sort yourself out. You’ve been fit all your life.”

‘And it completely transformed the way I thought. From that moment on, I started at it again.’

Why Neville Calls Exercise a Form of Medicine

These days, Neville says training has become non-negotiable.

He’s not preparing for a sporting event or chasing specific performance goals, but he notices a significant difference in both his physical and mental wellbeing whenever he stops exercising for too long.

‘I feel like I can’t go without training,’ he explained. ‘If I go three, four or five days without training then it’s not the end of the world, but if I go two weeks without it, I start to feel heavy.

‘I start to feel like I’m losing strength. You start to feel like you’re going under a little bit. I didn’t prepare for the fact that not training, eating more and not being able to cope without that fitness structure in my life every single day.’

The former Manchester United captain believes the mental benefits are just as important as the physical ones.

‘People who don’t train are missing out on a great medicine,’ he said. ‘I stopped for two to three years and the impact it had on my mental health was terrible.’

More than a decade after retirement, Neville’s routine looks very different to the one he followed as a professional footballer. But the principle remains the same: move regularly, stay consistent and make exercise part of your day rather than something you squeeze in when you get the chance.


If there’s one thing Kori Sampson knows, it’s how to optimise your body composition for performance. To tap into his knowledge as an elite athlete and coach, we asked him to create a 4-week plan to help you move faster, recover quicker and keep pushing when the fatigue sets in – all while improving your muscle-to-fat ratio.

An expert personal trainer says this practical exercise boosts core strength and upper-body stability more than planks

It’s often the simplest core exercises that are most effective, and the farmer’s carry fits perfectly into this box. Done with two kettlebells or dumbbells and a bit of space, it’s one that all can do to improve core strength, full-body stability, and strength.

While planks and sit-ups are core exercises with many of the same benefits, this one is particularly unique in how it translates to real life. It’s a functional exercise, says Kate Rowe-Ham, an expert personal trainer, author of The Longevity Solution, and the founder of Owning Your Menopause, translating to everyday movements like carrying shopping or climbing stairs.
