Thanks so much, PPs!! I just looked at the website for the Cabin John rink, and it looks like they have adult or open skate times after 8pm several nights of the week. I totally want to go now!! It really sounds like fun to do something different for a change. Now I just need to get DH home from work early enough to make it possible more than once in a while.
To the Austrian skier - thank you! Squats and lunges were along the lines of what I was thinking, and the wall sits are a very good idea. I will start doing them tonight. Would deadlifts be of any help? I only have hand weights at home, but even unweighted the one-legged deadlifts left me plenty sore the next day when I was doing them in the past.
