Aching muscles, thinning hair and a few more greys – hitting 40 can be a big wake-up call for men. It’s the decade when your body starts reminding you that habits from your 20s and 30s may no longer be enough.

The good news is that your 40s are also the perfect time to invest in your long-term health. Small but consistent changes to your exercise routine, diet and lifestyle can pay huge dividends, helping you stay healthier well into your 50s, 60s, 70s and beyond.

Today, we’re exploring six ideas for how men in their 40s can maintain their health.

1. Prioritise strength training

If you’re only going to do one thing from this list, make it strength training.

As you enter your 40s, your muscle mass naturally begins to decline – those big biceps you always had may start looking a little smaller. While maintaining muscle naturally can help you look good and feel more confident, it also plays an important role in supporting your metabolism, maintaining bone density and preserving long-term mobility.

This makes resistance training more important than ever. Aim to do at least two strength sessions each week, focusing on compound exercises such as squats, presses and rows. 

If you aren’t keen on gyms or lifting weights, you can maintain muscle by working out at home with dumbbells, resistance bands or bodyweight movements such as press-ups, pull-ups and squats. 

2. Don’t neglect your heart

While strength training is crucial, cardio wellbeing is equally important for men in their 40s. Heart disease remains one of the biggest health risks for men, yet many don’t think about their cardiovascular health until something goes wrong. 

To ease your concerns, start incorporating regular aerobic exercise into your week, whether that’s brisk walking, cycling, swimming, running or rowing. If you’ve never done cardio, start slowly, build up, and be consistent. Ultimately, a twenty-minute walk each day beats an ambitious 10k plan you never stick to.

On top of this, don’t ignore routine health checks for your blood pressure and cholesterol levels.

3. Make recovery part of the plan

As we’ve established, exercise is paramount after 40 – but rest and recovery are just as important. This means prioritising quality sleep, stretching and rest days. Yes, this is a great excuse to enjoy some time on the sofa!

Joking aside, most adults need between seven and nine hours of restorative sleep each night, and giving your body ample time to recover will help you perform better both in and out of the gym.

4. Eat for longevity

Your 40s is a time to focus on eating in a way that’s healthy and sustainable for you. 

This means forgetting fad diets and instead eating plenty of vegetables, fruit, whole grains, legumes and lean protein (e.g., lean meat, fish or tofu). At the same time, aim to cut back on refined sugar, processed meats, and excess alcohol.

Small improvements to your everyday diet are far more sustainable than restrictive eating plans that rarely last, and allow you to enjoy your favourite foods in moderation.

5. Look after your mental health

Midlife often brings new pressures, from demanding careers to caring for children or ageing parents – or everything, all at once. Managing your stress is therefore just as important as maintaining your physical fitness. 

Find ways to maintain good mental wellbeing. Regular exercise will help, but so will maintaining close friendships, spending time outdoors, and immersing yourself in hobbies, music, art and culture.

If you’re struggling, don’t be afraid to reach out. Whether it’s a therapist, counsellor or trusted friend, talking things through can make a real difference.

6. Stay on top of preventative health

Let’s face it – nobody likes going to the doctor. Unfortunately, many men avoid the GP unless they’re seriously ill, when prevention is often far easier than treatment.

This is your reminder to keep up with routine health checks, discuss any persistent symptoms early, and be aware of changes to your body. Catching potential problems sooner often leads to better outcomes and greater peace of mind.

The Final Word

Your 40s are not the beginning of the end, but the decade where smart habits start to matter more than ever. 

From hitting the gym to getting enough sleep, the choices you make today will shape how you feel in the next few decades. Stay consistent and your future self will thank you.
