" There are two more things that I do regularly to keep my legs the way I want them:
1. I just walk around my apartment with my toes pointed straight in. Of course one looks like a pigeon, so do it when you're alone. But try always to walk that way when you're puttering around alone. You'll feel all the leg muscles responding.
2. Bend down and put your palms flat on the floor, keeping your knees straight. Then walk 'fourlegged' across the room (or down the hall if you're sure you won't frighten anyone) and backwards again. This is wonderful for both arm and leg muscles, and it draws blood to the face, which helps the complexion. "
