Ok just some info that might help if you are siht at press-ups. I have been having tons of trouble with press ups. Maxing out after 20 or so. I couldnt understand it because my arms are like tree trunks and I have no problem bench pressing the equivilent weight at the gym etc.. I was really stumped. Stabandswat suggested I try the plank.. a pilates exercise. You basicly stay in press-up "up" position for as long as you can. I tired this and found my problem. I could only hold the up-position for about 2 minutes.. thus I deduced that the problem is not in chest/arm strength but in core strength. I have been working on the plank, holding it for longer each day (now got it up to 4 & 1/2 minutes and doing back extensions and crunches.. I havnt done press ups for about 2 weeks. Guess what? I tried for a best effort inside 2 minutes today and knocked out 50 with little problem. So if you suck at press ups, work your core! J.
