Exercise Advice: This exercise is done in a standing position with your feet close together. Hold a dumbbell with your right hand and 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.
