How it counts
Your newest number is your level.

Length
One year from the day you start
Build up to 100 push-ups in one set, with no resting on the floor or your knees. A push-up counts when your chest comes down to a fist's height off the floor and your body stays straight.
Test your max about once a week, fresh and warmed up, and log the whole set: if you did 27, log 27. Your newest test is your level, so an off day shows too. Training days don't need a log.
