The Claim

Resistance training, whether meeting the recommended guideline of at least two sessions per week or measured by monthly volume of up to 2033 MET-minutes, is not statistically significantly associated with all-cause mortality in U.S. adults over a median follow-up period of 13 years, even after adjustment for age, sex, and other physical activity levels.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In U.S. adults, engaging in resistance training at or below the recommended frequency or volume does not show a statistically detectable link to changes in the risk of death from any cause over 13 years, even when accounting for age, sex, and other forms of physical activity.

See the scientific wording

Resistance training, whether meeting the recommended guideline of at least two sessions per week or measured by monthly volume of up to 2033 MET-minutes, shows no statistically significant association with all-cause mortality in U.S. adults over a median follow-up of 13 years, even after adjusting for age, sex, and other physical activity levels.

Why this might work

Doing weight training, even regularly or at high volumes, does not change the underlying body processes that determine how long a person lives, because it doesn't affect the main causes of death like heart disease, cancer, or organ failure.

  1. Study: Associations Between Resistance Training and All-Cause Mortality: NHANES 1999-2006.

    This study looked at thousands of adults over many years and found that people who lifted weights two or more times a week, or did a lot of weight training, didn’t live longer than those who didn’t — even after accounting for other healthy habits.
