• A systematic review and meta-analysis in the March-April 2023 issue of Missouri Medicine concluded that, above 60 minutes per week, strength training begins to backfire. Above 130 minutes per week, your life expectancy becomes the same as if you were sedentary
  • A systematic review published in the British Journal of Sports Medicine in 2022 also found a J-shaped association between strength training and all-cause mortality, with a maximum risk reduction (10 % to 20%) being observed at a dose of 30 to 60 minutes per week. After 60 minutes, the benefits started to diminish, and above 140 minutes per week, it was associated with an increased risk of all-cause mortality

Benefits of moderate exercise, loosely defined as exercising to the point where you’re slightly winded but can still carry on a conversation, cannot be overdone. There’s no point at which moderate exercise starts becoming negative (source)
