text: i can't do a pushup to save my life? how do i get strong enought to be able to do 50 man pushups? 50 regular push ups will not be easy. chest, shoulder, and tricep strength will need to be built before you can start. do modified push ups until you can get to 50.   once you can do that you should start in the push up position and lower your self down to the ground, if you cant come back up do modified push ups from your knees  until your arms are fully extended-lift your knees up and lower yourself back down. repeat that.  do not do push ups more than once a day at this point, you need to rest the muscles and repair a little.  good luck!
