Experts Share The Bare Minimum Amount Of Exercise You Need To Be Healthy
Exercise is indisputably one of the best things you can do for your brain and body. Which begs the question (at least from me) ― what’s the absolute bare minimum I have to do to get by?
So, we at HuffPost UK thought we’d speak to some experts about the topic for the sake of ourselves any curious reader.
We chatted to Dr. Richie Kirwan, Lecturer in Exercise Physiology at Liverpool John Moores University (LJMU), and Olivia Tyler, National Fitness Assurance Lead at Nuffield Health about what exercise is, how much of it we need to do, and whether or not the levels change as we age.
Here’s what we found out:
Well, let’s start off with what exercise really is
“The UK currently has guidelines for physical activity which is different from exercise,” Dr. Kirwan informed HuffPost UK.
“Physical activity is any movement that requires you to use energy to move your muscles so can be things like walking or cycling to work, cleaning the house, gardening, etc.
“Exercise, on the other hand, is any structured/planned movement that we carry out with the specific goal of improving or maintaining our health or fitness ― so cycling to work is physical activity but going for a cycle after work to stay fit is exercise.”
You’ve probably heard recommendations for 150 minutes of physical activity a week.
But, Dr. Kirwan points out, this is for moderate-intensity activity; it drops down to 75 minutes if you’re going harder (ie exercising to a level that makes breathing hard and fast and makes it difficult to speak).
“We [at LJMU] have a lot of research showing that vigorous or more intense activity is more probably more beneficial, or equally beneficial in a shorter period of time,” the doctor points out, “but combining moderate and vigorous is probably an even better option.”
So, the harder I work out, the less time I can spend in the gym?
Well, don’t skip taking the stairs and enjoy your morning walk if you can, as moderate physical activity is great. But possibly, yes ― adding some intensive exercise may be a less time-consuming way of getting those minutes in.
“At LJMU we’ve done quite a bit of research on High Intensity Interval Training (HIIT) and shown you can get many of the cardiovascular benefits as more moderate exercise in a shorter amount of time,” Dr. Kirwan shared with HuffPost UK.
“And in the modern world, many people are time-poor, so time efficiency is important.”
Then, there’s lifting weights and doing other strengthening exercises; these can help to prevent “muscle and strength loss with ageing (called sarcopenia)”, Dr. Kirwan says. Sarcopenia is associated with conditions like diabetes, heart disease, and bone conditions.
“Doing strength-focused weightlifting workouts can take more time as you need more rest between your sets to recover so this might not be achievable when life gets really busy,” Tyler said.
But “Some people like to split their weeks into different areas of their body, for example doing chest and tris on one day, back and bis on a separate day and legs on another” ― this can help to save time.
Do I still need to exercise as much as I age?
Grip strength is a greater indicator of cardiovascular risk among older people than even blood pressure ― so it’s no surprise that Dr. Kirwan says “exercise is something we should all do throughout our lives but is probably even more important for older people.”
He added that while older people newer to exercise “should speak with an exercise professional who can introduce them to the correct activity and intensity to start at (based on their fitness level and mobility),” age shouldn’t deter people from intense activity.
He mentioned one study involving a 93-year-old Irish rower who took up the sport at 73 and became a champion in his 90s.
70% of his routine consisted of the easier physical activity we talked about earlier ― but when he did practice rowing, he upped the intensity week on week.
“A lot of people don’t think about progression at all but it’s important,” Dr. Kirwan said. “We get used to exercise eventually and need to continue to challenge ourselves with intensity etc.”
So, what’s the bare minimum I have to do?
Both experts agree that some exercise is always better than none, across all age groups.
“The guidelines are that anything is always better than nothing. Your workouts should be built into your week as part of your routine and so you can only fit in what you have time for,” Tyler says.
Dr. Kirwan agrees, saying “if someone is completely inactive, starting any form of physical activity (as long as it’s not too strenuous) is beneficial.“
But to make those minutes count more and work harder, it’s a good idea to combine sneaky workouts (like gardening, cleaning, and walking to the shops) with intentional exercise sessions; if you want to chop down your time in the gym, make those intense, and try to progress in your chosen exercise every week.
Strength training is important, too ― by mixing up your workouts and strategically moving your body, you should be able to optimise the 75 minutes of moderate-intensity exercise (or 150 minutes of more easy-going physical activity) experts prescribe.

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.
Upright row
- 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.
Serve the platter
- 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.

Sue Barker, 70, keeps fit with cardio, strength training and NEAT exercise – her lifelong fitness formula
Sue Barker may have stepped away from professional tennis in 1985 at the age of 29, but she’s continued to prioritise fitness and movement.
‘During the winter, I try to exercise at least three times a week at the gym, and in the summer I like to get outdoors. I love jogging, cycling and walking my dogs,’ the 1976 French Open champion and former world No. 3 told Express.
She shares her varied routine – which includes cardio, strength training and plenty of everyday movement (also known as non-exercise activity thermogenesis, or NEAT) – with her husband.
‘As a rule, Lance and I do a lot of exercise – we have two dogs to walk [twice a day], we cycle a lot and have a personal trainer we see a couple of times a week,’ the former long-time Wimbledon presenter told Sheerluxe.
‘So, I do keep fit. Lance plays golf and I’m thinking of taking it up, but I’ve been saying that for quite a few years…’
Despite retiring from both tennis and broadcasting, she remains drawn back to the court.
‘Going back to Wimbledon [in 2023] reignited my love for the game, so I’m going to play there on the grass,’ she added.
Sue Barker uses exercise to stay fit for life
Movement plays a central role in her approach to healthy ageing and maintaining her independence.
‘It’s vitally important to me that, even later in life, I stay fit and focused,’ she told Express. ‘For me, it’s a question of self-preservation. While I can’t fight time, I can help myself stay fit and focused through good nutrition and a healthy lifestyle.’
She also remains keen to embrace new experiences and make the most of the years ahead.
‘I can’t wait to see where my life is going to go from now on. Age is but a number,’ she told Riverstone Living. ‘I want to go out and do all sorts of things – I want to travel, I want to keep living life to the absolute full.’
How Sue Barker first fell in love with sport
Her love of staying active started at home.
‘My father was very sporty and played a lot of tennis,’ she told Sheerluxe. ‘He was also a very good golfer and, as a family, we did a lot of active things together like rowing and swimming. My siblings did all sorts of sports too and I learned to play tennis mainly with my sister.’
Playing tennis in an era before modern recovery methods and training techniques helped forge her into a resilient athlete.
‘We didn’t have the facilities and the training and the technique that goes with it now – the stretching, the ice baths,’ the former champion recalled.
‘We wore Green Flash tennis shoes that didn’t have any sponge in them at all, and we were using wooden rackets. Every part of your body ached.’
