It’s back to Pilates, and a good thing, too: I was getting stiff. We did a lot of body core exercises. We raised and lowered our legs. I tried to learn to relax my back and thigh joints while holding my legs up. We curled and uncurled on the floor. We twisted from side to side through the ribcage, without moving our hips. We lay on our sides and swung our legs back and forth.
