Once a week I do Pilates. I really enjoy the effects of it: my body is more balanced, I get a lot less aching in my shoulders, I run faster with less training. What I don't enjoy so much is the actual act of doing it. It's very finicky, and concentrated. But the rewards for effort are enormous, so I will certainly continue doing it. In order to amuse myself, and possibly by instructor, I made a pair of Tulip socks to wear to Pilates.
