This can be done as a modified push up also (from the knees)
Remember, each push up should end with your elbows 90 degrees and your back completely straight with the core engaged. Your head should not be down, rather looking about six inches ahead. Your chest should go low enough where it could hit a fist on the floor. 100 half-a** push ups do less than 10 proper push ups. DO NOT CHEAT YOURSELF!!!
(A great link for motivation on doing exercises with the proper form)
your goal is to do 100 push ups.
As soon as you lose form and/or cannot do any more PROPER push ups, you stop and do 20 squat jumps. You then go back to where you left off (let’s say 18) do as many as you can (let’s say you get to 24) then do 20 more squat jumps. You continue to do this until you get to 100 push ups.
