Can exercise boost your immune system? Yes, if you do it correctly – here’s how

Convinced something ‘is going around’? You could be right. People on Reddit are claiming they’re experiencing the ‘worst cold ever’ this winter, while the UK’s Health Security Agency has issued advice over rising flu and RSV cases. The good news is that exercise could help protect you from catching anything. We asked Women’s Health Collective trainer India Morse for her advice, including whether you really can ‘sweat it out’ if you’re already sick, and what type of exercise is best to boost your immune system.


When can exercise boost my immune system?

‘Exercise certainly can boost your immune system, but it’s worth keeping in mind that – as ever – prevention is better than cure. If you’ve already contracted symptoms, it will take more time to recover. The standard rule of thumb is that you should avoid training until your symptoms are above the neck, like congestion, sneezing or a sore throat. Studies show that exercising with more severe symptoms can make you feel worse, so it’s important that you listen to your body.’

Studies show moderate exercise is best for boosting your immune system

‘Once you feel ready, research by the Journal of Sport and Health Science has shown that moderate-intensity aerobic exercise can stimulate cellular immunity by increasing the circulation of immune cells in your body. This means your body will be better prepared to fight off future infections, while the increased blood flow will provide your cells with the oxygen and fresh nutrients needed to get back to full health.

‘The aforementioned study recommends daily workouts lasting 30-45 minutes, but as you’re already unwell, start with 15 minutes of mild to moderate exercise and see how you feel the following day. Try a light jog or a short outdoor speed walk to avoid infecting others, if your illness is contagious.’

How can exercise boost my immune system?

‘Other research has shown that your body temperature increases and remains elevated for a short time after a workout. This rise in body temperature can prevent bacteria from growing, while helping your body to fight off infection, since it stimulates your immune system and bacteria and viruses can’t survive in higher temperatures.

‘Another big bonus of exercise is its ability to supercharge sleep quality, and research shows that sleep can weaken your immune system and make you more susceptible to the common cold and cardiovascular and metabolic disorders, since sleep is when your body produces antibodies – proteins in your cells that bind to unwanted substances and get rid of them.

‘Naturally, you’re probably feeling more stressed than usual if you’re already unwell. Moderate exercise has also been proven to slow down the release of stress hormones, while separate research has shown that stress can impact your immune system by impairing the function of natural killer cells (or NK cells), which protect you from infection and disease. The more consistent you are with moderate exercise, the stronger your NK cells.’

How often should I exercise to boost my immune system?

‘Remember that exercise is more effective in staving off illness than it is in curing it. As research proves, stick to 30-45 minutes of daily moderate exercise, like brisk walking, tennis, Pilates, yoga or riding a bike and, I’d wager that the number of sick days you’ll take will reduce. If you do happen to be someone that’s already feeling unwell, rest up until your symptoms move above the neck, and ease off if you start to go downhill. Patience is a virtue.’

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core

Joan MacDonald didn’t enter a gym until she was 70. Really. Since then, the 80-year-old has transformed her health by losing three stone and building significant muscle, and now coaches other women through her training platform, Train With Joan, which she launched to help others boost their fitness at any age.

The premise of her app is simple: minimal-equipment workouts built around no-fuss, effective exercises that can be done anywhere. One ‘powerful core and stability exercise’ she swears by is alternating bodyweight clock taps. ‘This movement helps strengthen the muscles that keep you stable, balanced and moving well as you age,’ Joan explains.

Bodyweight clock taps benefits

Think they look too simple? That’s the point. Joan is adamant that ‘You don’t need complicated workouts to start getting stronger. Sometimes the most effective movements are the simple ones you do consistently.’

According to Joan, regularly performing bodyweight clock taps help:

  • ‘Strengthen your core which supports your spine and reduces strain on your lower back.
  • ‘Improve balance and coordination, helping you stay steady on your feet.
  • ‘Increase hip stability, which supports your knees and joints.
  • ‘Build functional strength for everyday movements like stepping, turning and reaching.
  • ‘Help reduce fall risk by improving control and body awareness’

How to do bodyweight clock taps

Find a demo from Joan above, along with instructions for how to do them with proper form below.

  1. Stand on one leg with a slight bend in your supporting knee and brace your core.
  2. Keeping your hips level, reach your free foot forward to lightly tap the floor in front of you (12 o’clock), then return to the centre.
  3. Continue tapping to different “clock” positions—such as 3, 6 and 9 o’clock—maintaining your balance and control throughout.
  4. Complete all reps on one leg before switching sides.

Form tip: Move slowly and focus on staying stable. The goal is controlled movement, not how far you can reach.

How many reps and sets to do

Joan shares her advice, according to your fitness level.

  • Beginners: ‘3 taps per leg x 8-10 reps’
  • Intermediate: ‘3 taps per leg x 10-12 reps’
  • Advanced: ‘3 taps per leg x 12-15 reps’

Tim Henman, 51, Has Barely Aged Since Retiring – Here’s His Fitness Formula

Tim Henman, 51, Has Barely Aged Since Retiring – Here’s His Fitness Formula

In the 19 years since retiring from professional tennis, Tim Henman has barely aged. A large part of that comes down to his approach to fitness. The 51-year-old believes that ‘being active is always going to be a part of my identity’, which helps him maintain a consistent training routine.

Even while spending much of his time covering tennis as a commentator and pundit, and serving on the board at Wimbledon, Henman still makes time for his own athletic pursuits. Especially now that he has a different kind of motivation.

How Tim Henman Stays Fit After Retirement

‘I’ve got a gym at home and I try to exercise pretty regularly because I feel much better for it,’ Henman tells Men’s Health. ‘But one of my passions is wine. So if I’m having a few glasses of wine – you’ve got to treat yourself – then that definitely incentivises me to get in the gym. I’ve always exercised and I think it’s good for me both physically and mentally.’

That doesn’t mean Henman is completing brutal workouts or chasing specific performance goals. Instead, he prefers a straightforward routine that supports his lifestyle and helps him manage the wear and tear accumulated during his tennis career.

‘I don’t run that much anymore. We’ve got dogs at home, so I walk them a lot, and if I’m at tournaments or working, I’ll do quite a bit of incline walking on the treadmill. Then it’s just a good mix of weights and core work. I’m not trying to run any marathons – I’m just trying to stay in relatively good shape,’ he says.

‘I understand my body and know what I can and can’t do, especially because I’ve had three elbow surgeries and a shoulder surgery. So I’m a little careful around those joints.

‘Posture is so important for shoulder health. I focus on resistance-band exercises to make sure I’m strong through my back and maintaining good posture. Then the core is so important, so I try to stay strong through planks and side planks as much as possible.’

Why Henman Is Excited for the Laver Cup

His approach to fitness has changed dramatically over the past two decades. Where he once played tennis every day, Henman admits he’s now lucky if he gets on court twice a year. These days, golf is his sporting obsession.

That doesn’t mean he’s any less passionate about tennis, however, as he prepares to return as Team Europe vice-captain at the Laver Cup this September at The O2.

‘I’m so excited,’ he says. ‘The first time I ever experienced the Laver Cup was at The O2 when Roger Federer was retiring. I’d never seen the event live and I was probably a bit sceptical at that stage. But I was there working for television and, for those three days, I was completely blown away by the delivery of the event, the intensity of the players and the quality of the matches.

‘Tennis is an individual sport and players spend most of the year competing on their own. But I’d struggle to name any player, male or female, who doesn’t enjoy being in a team environment every once in a while.

‘The way the Laver Cup has evolved and grown is so special, and Federer deserves a lot of credit for that vision.

‘With an arena like The O2, it’s one of the biggest venues in tennis. There’ll be 17,000 or 18,000 people packed in there and, with the roof on, the atmosphere is incredible.’

Laver Cup returns to The O2, London, from 25-27 September, bringing together many of the world’s biggest tennis stars as Team Europe takes on Team World in the sport’s unique team competition. Tickets are on sale now via AXS, the official ticketing partner of The O2. Visit lavercup.com for more information.
