Exercise Advice: Sit on a flat bench or any sort of chair with your back upright. Lay a barbell across the top of your thighs (you can add wight to the barbell for added resistance if you like). This exercise is performed just like the seated calf raises: place your toes on the ground and push your toes down so that your heels become raised so that you are on your tippy 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 quick and explosive.
