Aw, you just reminded me of something. My grandma used to wash out soup cans, then use them to bake small raisin breads. She would make several at once and you could freeze them. I don't know where she got this idea but it was awesome always having these tiny raisin breads available :) especially if you don't want to commit to a whole full-sized loaf!
There are many variations, but basically you start in a standing position, jump down to a plank, do a push up, jump back up to standing, and jump in the air. That's one rep.
