HOW: Get set-up in front of a wall or an object to use for balance. While keeping your glutes and quads tight to keep your knees straight, lift your heels off the ground in a slow and controlled manner. Hold this position for the desired amount of time. Really drive the balls of your feet into the ground.
FEEL: You should feel your calves getting a workout, but also your glutes and quads working as well to help keep your legs straight.
COMPENSATION: Do not let your knees bend as that is a different exercise. Do not shift your weight side to side. Make sure you go through your full range of motion at your ankle. This is not a balance exercise, so hold onto something to help with balance as the goal of this exercise is to strengthen your calves!
