Hey all.
As you probably read in the title, I'm currently in a cast for 4-6 weeks with a broken right hand.

Obviously this puts that hand out of commission for a while.
What I was wondering was what I could do for these few long weeks to
A. keep my drum skills sharp, and
B. strengthen my left hand since it's naturally weaker then my right.
Any kind of exercises are welcome. Anything that will keep me occupied for a little while.
Thanks guys!
