You’re Spending Too Long in the Gym. Here’s Why.
New data reveals the longevity sweet spot for strength training, and most people blow past it.
Large pooled cohort studies and meta-analyses spanning decades and roughly 100,000+ participants found the amount of strength training associated with longer life. The number is 90 to 120 minutes per week.
I do about 20.
Before you tell me I’m wrong, read the data more carefully. Because buried inside this research is something the headlines are missing: above 120 minutes per week, all-cause mortality risk stops declining meaningfully, with little additional reduction at higher volumes.
That plateau suggests there may be a threshold beyond which additional training delivers diminishing returns for longevity.
In observational data, 90 to 120 minutes per week associates with roughly 10 to 25% lower all-cause mortality risk, with cardiovascular outcomes and some neurological outcomes showing similar benefits. Those are significant numbers. What the research also found is that people doing two or three times that amount saw little additional longevity benefit.
So the real question is not how much you should train. It is how efficiently you can reach the range that actually gives you results.
