Folks,
I would suggest respectfully, but firmly, that you should visit a orthopedic hand specialist or sports med doc BEFORE embarking on these exercises.
Tell the doc what you want to accomplish and ask for a script for PT.
I am typing this with old, gnarled, arthritic hands and fingers, replete with ganglion cysts.
Never imagined I would have so many busted parts at retirement.
