When untrained young men lift heavy weights three times a week for five months, they get much stronger—some exercises more than double their original strength.

Effects of a 20-Week High-Intensity Strength Training Program on Muscle Strength Gain and Cardiac Adaptation in Untrained Men: Preliminary Results of a Prospective Longitudinal Study

Cohort Study

Human

2023 Oct 24

This study gave untrained young men a 20-week intense weightlifting program three times a week, and their muscles got much stronger — exactly as the claim says. Their lifts went up by 40% to over 100%, and their leg strength improved too.

Similar Assertions

Lifting heavy weights fewer times, three days a week for a month, helps young active men build more muscle and get stronger than lifting lighter weights many times.

People get noticeably stronger in just 4 weeks of heavy weightlifting—even before their muscles get bigger—because their nerves learn to fire better.

Lifting heavy weights for 10 weeks makes you stronger, no matter how long you rest between sets or how many reps you do, as long as you’re lifting around 80% of your max.

If you're already fit and lift weights, doing 5 to 10 sets per muscle group each week will make you stronger—but doing more than that (like 15 to 20 sets) won't make you any stronger, no matter how hard you push.

If you're already strong and lift weights, training each muscle group either once or five times a week for eight weeks will give you about the same strength gains on the bench press, squat, and row.
