So, I've been waiting for almost three weeks for my new fork to show up at Performance (woodgrain Lager), and I haven't ridden since my accident (9/21) and I'm bored as all get out. I miss my bike. What are some good exercises to keep my leg strength and all that up while I'm out of the saddle? Reading the forums and urbanvelo and Bicycling magazine just aren't cutting the cravings anymore. FYI: they can't be too demanding of the upper body at the moment. my Shoulder is still super sore, and cracked ribs are a bizznitch.
