getting harder muscles

Quote; "A recent article in the American College of Sports Medicine’s Medicine and Science in Sport and Exercise found evidence for muscle fiber hyperplasia in anabolic steroid using powerlifters. This however, is pretty much the first evidence of a mechanism for hyperplasia in humans. [Editor’s note: there is fairly long-standing evidence that hyperplasia does occur in (of all things) weight trained cats.]" - Bodybuilding.com

Weight trained cats?!? Tha's wild! And no, I am not recommending the use of anabolic steroids.
