Right now, I'm pretty good all around on the PRT. However, I can never seem to get as many push-ups as I want. I'm tall and lean, more built for running, and so the running is always easy for me. However, I can't ever seem to max out the push-ups on the PRT. I try to work on my push-ups daily, but I can't seem to increase my max. Does anybody have any suggestions on what I should be doing better? I've tried just maxing out time after time, pyramids, and just lots of sets of smaller numbers, but because I'm so lean, I can't seem to put on much more muscle mass or boost my numbers significantly. Thanks for any help.
