Strength Training for Men Over 40

I've been coaching men over 40 for more than four decades. The same patterns show up every time: guys who trained hard in their 20s and 30s hit 40 and either don't change a thing (and start accumulating injuries) or back off completely (and start losing everything they built). Neither extreme works. Here's what does.

What Actually Changes After 40

Testosterone decline. Natural testosterone peaks in your mid-20s and declines roughly 1% per year after 30. By 45, you may have 15–20% less testosterone than you did at peak. This doesn't prevent strength or muscle gains — but it slows recovery and means you can't train as frequently or with as much volume without paying a price.

Connective tissue recovery. Tendons and ligaments are more conservative about adapting than muscle tissue. They need more time between heavy sessions. Ignoring this is how you end up with elbow tendinitis, shoulder impingement, or a knee that talks back to you for six months.

Recovery window. Your muscles recover from intense training in 48–72 hours. Your CNS (central nervous system) and connective tissue take longer. Training a muscle group twice per week with adequate rest is almost always more productive than three times per week with insufficient recovery.

The Framework for Men Over 40

3–4 training days per week. Full body or upper/lower split. Not a bro split where you train chest once a week — you want each muscle stimulated at least twice per week for optimal muscle protein synthesis.

Heavy compound movements as the foundation. Squat, deadlift, bench press, overhead press, barbell or dumbbell row. These are still your best tools. If a movement is causing joint pain, modify it — don't abandon heavy lifting, find a variation that works for your structure.

Rep ranges: 5–12 per set. Both lower rep (5–8) and moderate rep (8–12) ranges build strength and muscle effectively. Varying the rep range across your training week gives you strength stimulus without accumulating excessive joint stress from constant max-effort work.

Deload every 4–6 weeks. One week at 50–60% of your normal training volume and intensity. This is not a week off — it's a week that allows your connective tissue to catch up to your muscle tissue. Skip deloads consistently and you will accumulate injuries.

Protein and Sleep: Non-Negotiables

1g of protein per pound of bodyweight. This is the research-backed target for maximizing muscle protein synthesis at this age. Most men are eating half this amount and wondering why they're not making progress.

7–8 hours of sleep. Testosterone is primarily produced during sleep. Growth hormone is released during deep sleep. If you're getting 5–6 hours, you're training against yourself. No program overcomes chronic sleep deprivation.
