Two Hours of Weekly Strength Training Hits the Sweet Spot for Longevity
Based on: Long-term resistance training with all-cause and cause-specific mortality: assessing dose-response and joint associations with aerobic physical activity.
In nearly 150,000 adults tracked for up to 30 years, doing 90 to 119 minutes of strength training per week was linked to a 13% lower risk of dying from any cause. More than two hours weekly added no extra benefit. Combining strength work with aerobic exercise gave the biggest mortality drop.
Key Insight
This study suggests around two hours of weekly strength training, paired with cardio, may offer the best longevity payoff.

Why Your Muscles Need This Enzyme to Reap the Benefits of Exercise
In mice and humans, a muscle enzyme called NOX4 drops as we age. This loss weakens muscles and dials down the body's natural defense system that exercise normally switches on. In mice, deleting NOX4 sped up frailty, fat gain, inflammation, and insulin resistance. Sulforaphane, the compound in broccoli sprouts, helped restore those protective responses.
Staying Active From Midlife Cuts Sarcopenia Risk by Up to 78%
In Norwegians tracked for over 30 years, those who stayed active from middle age into their 70s had 78% lower odds of confirmed muscle loss. Even people who started exercising later in life saw meaningful benefits. People who became inactive lost most of the protection.
Selenium Levels and Fatty Liver: Is There a Sweet Spot for Survival?
In nearly 1,800 American adults with fatty liver disease, those with higher blood selenium had a 64% lower risk of dying from any cause compared to the lowest group. But the benefit plateaued once selenium hit about 200 μg/L, so more wasn't better. Older adults and people with high blood pressure seemed to benefit most.
