I have recently started a workout which I call the double up. Its called that because you pick a starting number (say 200 push ups) then every 2 days you double the number. (you have all day to get it done) but if you physically cant double it again you stay on the number for another 3 days. Example day 1 200 push ups day 2 200 push ups day 3 400 push ups day 4 400 push ups day 6,7,8 400 (if you couldent get 800) also you rest on saturday and sunday Its designed to push you to the limit then once you find your limit you break it to pieces then find your new limit. So what do you think.
