I recently began SS and, therefore, am benching or pressing every Monday, Wednesday, and Friday. Since I'm in the military, I need to maintain decent push-up endurance for the sake of PT tests. I'm planning on working on push-ups once a week or so to at least maintain my current numbers. What would be the best day to work on push-ups? Would it be best to do them on a bench day, press day, or on Saturday when I will have an extra day to recover? Any input would be greatly appreciated.
