Begin in a standing position with your feet hip-widths apart.
Keeping your left leg straight and strong, put weight into your left foot to find balance and raise your right knee to hip level. Stand tall with a neutral spine.
Staying balanced on your left leg, raise your left heel off the floor so you're standing on your toes. Raise your heel as high as you can without losing your balance; hold onto a wall or chair if you need help balancing.
