Have the balls of your feet placed on the platform and heels hanging off it.
With your lower back against the pad, drive your heels upward to lift the weight.
Steadily lower the heels down until your calves are fully stretched and repeat.
Using momentum to drive the weight up and down.
Feet being too wide or narrow, keep it shoulder width.
Upper body swaying with the movement, keep it still.
Adjust the padding to be on top of your lower back when your calf is fully stretched. Then position your feet forward and spaced roughly shoulder width apart. Position the balls of your feet on the platform so your heels are hanging off.
Start by driving your heels upward and steadily lower your heels downward until your calves feel fully stretched. Pause briefly then drive your heels back up as high as comfortable. You should feel the weight on the inside of the balls of your feet when performing the exercise. Repeat for the desired amount of repetitions.
Avoid using momentum to bounce up the weight.
