Training after 40 is different. Not harder - different. Recovery takes longer. Injury risk from poor programming is higher. Hormonal response to training changes. What worked at 25 doesn't work the same way at 45.
This isn't a reason to train less. It's a reason to train smarter. Evidence shows that men who train consistently through their 40s and 50s maintain significantly higher testosterone, lower cortisol, better insulin sensitivity, and better lean mass than sedentary peers - with growing divergence over time.
This is the programme structure. Evidence-based, built around what works for the physiology of men over 40. For a reset that pulls all of this together away from normal life, my piece on how to plan a solo health retreat for men covers the structure that actually works.
I've been training consistently since my mid-30s. The programme I use now is fundamentally different from what I did at 32 - less volume per session, more recovery time, more zone 2, fewer ego lifts. My body composition at 43 is better than it was at 38. Training age matters more than calendar age if you do it right.
The Principles
Compound movements first. Squat, deadlift, bench press, overhead press, barbell or dumbbell row. These drive the greatest hormonal response and the most functional strength. Isolation exercises are secondary: supported by the mobility work covered in my piece on mobility and flexibility for men over 40.
3 sessions per week, not 5. Recovery capacity declines with age. Testosterone production after resistance training takes longer to restore. Three well-designed sessions with adequate recovery outperform five mediocre ones. If you are starting from scratch in your fifties, see my beginner's guide to strength training over 50. If you're still looking for the right gym, the UK gym comparison guide breaks down the main chains by equipment, price, and culture.
Progressive overload, every session. Add weight, reps, or sets. Without progressive overload, training is maintenance at best. Write every session down.
Zone 2 cardio separate from lifting. Don't combine intense resistance training and intense cardio in the same session - cortisol compounds, testosterone suppression compounds. Do them on different days.
Sleep is training. Without 7-9 hours, the hormonal environment for recovery doesn't exist. No programme fixes a 5-hour sleep habit.

Zone 2 Cardio - 3x Per Week (off days)
30-45 minutes at conversational pace. Cycling, rowing, incline walking, easy jogging. Heart rate 110-130 bpm for most men over 40. This is not a rest day - it's active recovery that reduces cortisol, improves cardiovascular health, and accelerates muscle recovery.
The Nutritional Foundation
Training without adequate nutrition is futile. The three non-negotiables:
Protein: 2.0-2.4g per kg bodyweight per day. For most men this means supplementation is necessary.
MyProtein Impact Whey Protein
25g protein per serving, under 130 kcal. The cost-effective way to hit your daily protein target. Use post-training or between meals.
Creatine: 5g/day, every day. Improves strength output, increases lean mass, and maintains muscle during any caloric deficit. The most studied supplement in sports science.
MyProtein Creatine Monohydrate
5g per serving, unflavoured, micronised. Take any time of day - consistency matters more than timing. Supports strength, lean mass, and recovery.
Caloric adequacy: Don't train in a large caloric deficit. Aggressive restriction while training elevates cortisol, suppresses testosterone, and impairs recovery. If losing weight, keep deficit under 400 kcal/day.
The Supplement Stack for Training Men Over 40
Beyond protein and creatine, these supplements have genuine evidence for training-age men:
Vitamin D3 + K2 (3,000-4,000 IU daily): Muscle function, testosterone, immune health. Most UK men are deficient October to April.
Magnesium glycinate (400mg before bed): Muscle recovery, sleep quality, cortisol reduction. Essential for men training 3+ times per week.
Omega-3 EPA/DHA (2-4g daily): Reduces exercise-induced inflammation, supports recovery, improves insulin sensitivity.
Bare Biology Life and Soul Omega-3
High-potency liquid omega-3 - 2,200mg EPA+DHA per teaspoon. UK-sourced, third-party tested. One teaspoon covers the daily training dose.
Track Your Hormones, Not Just Your Lifts
For men over 40, training and hormones are inseparable. If your testosterone is chronically low, training response will be blunted - you'll put in the work without the results. If cortisol is chronically elevated (overtraining, work stress, poor sleep), recovery will be compromised.
Test twice yearly - once in January (post-holiday, winter vitamin D low) and once in July (post-summer). This gives you a clear picture of whether your training is supporting or suppressing your hormones.

Common Mistakes Men Over 40 Make in the Gym
Training to failure on every set: Increases cortisol, extends recovery time, increases injury risk. Train to 1-2 reps shy of failure on most sets.
Too much volume per session: 4-5 exercises per muscle group in one session creates more cortisol than muscle. Less, heavier, better recovered is the formula.
No deload week: Take one week every 6-8 weeks at 50-60% of normal volume and intensity. Testosterone, strength, and wellbeing all improve post-deload.
Skipping zone 2: Men who only lift without aerobic work miss the cortisol regulation and cardiovascular benefits that zone 2 provides. Both are required.
Three compound sessions per week plus three zone 2 sessions is the evidence-based sweet spot for men over 40. Progressive overload, adequate protein, creatine, and sleep are the non-negotiables. Track hormones twice yearly - your bloodwork will tell you whether your training is working as it should.
