Gregor Posted November 17, 2009 Share Posted November 17, 2009 Hard to say, becasuse nobdy measure their gains on muscle mass The most gains are in the begining when gymnast is starting to train hard. Second big gains are more or less after 15-20 years of age. Link to comment Share on other sites More sharing options...
