Exercise Advice: This exercise is done in a
standing position with your feet close together. Use your left hand
to stabilize yourself on a fixed structure such as a barbell rack
or incline bench. Lift your left foot slightly off the ground and
begin the exercise with your right calf muscle. Push up with your
foot and rock up onto your toes. Be sure to really flex your calves
at the top of this movement for a one-count. Return to the start
position and repeat until failure. The initial upward movement should
be slow and controlled.
