Tie a light resistance band in a loop, then tie a clothesline-weight cord to the knot. Sit in a chair. Extend your legs, keeping your heels on the floor and toes pointing up. Put the loop around your left foot and under your right foot. Hold the cord in your right hand. With your left hand on your left knee, turn the toes of your left foot out, then back to the center. Do this 10 times. Then point your toes lower and repeat the exercise for 10 repetitions. Repeat both sequences with your right foot.
