HOW: Get set up standing on both feet with good arch position. Begin the exercise by leaning forward and shifting your weight and center of gravity towards your toes. Go just until the point that you can control and not let your heels lift off the ground. Push the front of your feet into the ground to return to starting position and repeat.
FEEL: This should feel like a control exercise, specifically your calf and foot muscles working to control your center of gravity shifting forward. You should also feel your calves and feet muscles working to return your body to starting position.
COMPENSATION: Keep your body straight, don't fold at your hips or arch your back with this exercise. Use your calves and feet muscles to do the work.
