I started doing the following strength/stretching routine 2-3 months ago to help gain back some mobility in the wrist that I broke in 2015. It helped quite a bit. I've since tried to do 3 sessions per week, but often it is only 2 sessions. I still cannot do many of the exercises, but I'm improving slowly which I think is good for this scrawny guy.
