Lifting lighter weights many times until you can't do any more builds as much muscle as lifting heavy weights a few times in people who already exercise regularly.
For young active men, doing lighter weights with more reps three times a week for a month might cause less muscle damage than lifting heavy weights with fewer reps, based on a blood test that measures muscle stress.
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.
Lifting weights with just a few heavy reps or many lighter reps gives about the same muscle growth when you do the same total work.
