12 push ups in a row with my hands on the weight bench today.
I've also been doing this shoulder warmup routine lately, and it seems to help a lot with the shoulder stuff.
It's funny how rehabilitating an injury like frozen shoulder is kind of like peeling an onion. Each time I regain some bit of range of motion or functionality, I go looking for some new exercise that exposes the next bit of restriction or muscle imbalance. And then I work on fixing that. Case in point - if you just ask me to lift my arms overhead, my left arm looks just as functional as my right. Hand me a kettlebell, have me press it overhead with one hand, and then walk around with it, and the left arm doesn't look so great any more. I can do it, but what is a pretty easy and natural motion with my right arm is a mess of wobbly stabilizing muscles and trying to avoid ugly compensations when I do it with my left. So, I'm working on that.
Also did some goblet squats, lunges, and sumo deadlifts today just so that my lower body doesn't feel neglected.
