Exercise Advice: Stand in an area near a squat rack and place a barbell on your shoulders, behind your neck (you may add weight plates to the barbell for added resistance). Begin the movement by slowly rocking back on your heels slightly so that your toes come off the ground about 2 inches. Once you have rocked back far enough, roll forward from your heels to your tippy toes. Be sure to really flex your calves at the top of this movement for a one-count and return to the start position. Repeat until failure.
