I play volleyball and I am only 5'8". I would like to know what to do to increase my verticle leap as much as possible in a short amount of time.
Start by doing calf raises with no weight then when that gets easy go to the smith machine or the leg press and do calf raises with weight. This is what michel Jordan does and my friend (who's in volley ball) told me a story about a guy who increased his vertical by about 10 inches doing this of course.
