I've been playing around with my Bosu the last few days. It had previously been collecting dust in the basement.
Working on the first of these exercises, finding how little my knee actually bends:
I know that the first one does mimic some aspects of skiing - because it affects my knee the same way =/ Which is a very specific experience I haven't had with any other form of activity. I'm hoping to use the Bosu exercise to isolate the source of the problem without having to actually be skiing. I'll see my trainer Weds and see if he has any ideas based on this information.
My trainer has me doing deadlifts, which are SO fun and rewarding for me. But my shoulder is acting up, and I suspect it's related to the weight I'm lifting. So. Boo.
He also has me doing this crazy core workout - decline situps. You set up a bench so that it's tilted upward with the roll-y foot attachment up top. Then, yeah, you hang from there and do situps. I do it at 30* and 45*.
And some shoulder stuff - lat pull downs, for example - to help my shoulder.
I didn't realize how much the lifting helps until I rode my mountain bike and did some yoga this weekend - both things I hadn't done in a few weeks. I have no cardio base, but my balance is on point. I was riding up muddy, slick switchbacks without losing my balance. Riding down and doing hops on all the little jumps and actually getting air. In yoga, chair pose wasn't even stressful!
Historically, yoga has helped my shoulder a ton. It's the only thing that's ever really fixed my shoulder. So ... I need to do that regularly.
