Place a foam roller under your right ankle, with your right leg straight. Cross your left leg over your right ankle. Put your hands flat on the floor for support and keep your back naturally arched. Roll your body forward until the roller reaches the back of your right knee. Then roll back and forth. Repeat with the roller under your left calf. (If this is too hard, perform the movement with both legs on the roller.)
