I have been dividing my studying time in 15 minutes slots for many years. A few summers ago - I think it was my summer vacation - I did pushups, squats and the likes after each 15 minute slot. Not many, more along the grease the groove lines. It felt great. (As you may have guessed, the regimen lasted only a few days. )
