I find more than 2 hours and 20 minutes of strength training in the danger zone… a bit hard to believe. One hour 3 times a week… an hour every other day seems reasonable.

The Metabolic Middle (30-60 minutes/week)

Strength training occupies the pyramid’s middle tier—far less time than walking but essential for maintaining muscle mass, bone density, and metabolic health. The dose-response curve is remarkably precise.

Optimal range: 30-60 minutes weekly (35% mortality reduction)

Danger zone: Beyond 140 minutes weekly, all benefits disappear3
