5 years ago before meeting you fine folk, I was exhorting runners to "move joints". Pretty simple mantra: move all the joints through the fullest range of movements, against a resistance hard enough to notice but not enough that you can't repeat it the next day. To me that's the fundamental step to stay healthy and avoid overuse injuries from "nothing but running".

But, it didn't involve a kettlebell, so I can't claim it was a DMPM variant.
