Can you keep your foot flat? Then you’ll master this lower-body exercise in no time
1. Stand up, putting most of your weight on your right foot. 2. Engage your right bum muscle. Make sure your weight is equally distributed over the balls of your big toe and little toe and your heel. Imagine those three points forming a triangle of support. Then lift your arch. 3. Hold your form as you lift your toes off the ground. Repeat 10 times. Then switch legs. Need a harder challenge? Try lifting your other foot off the ground at the same time.
