Go to theGNC store and get DOMS Ease. The soreness is Delayes Onset Muscular Symptoms. These pills help to work out longer and harder with less soreness. My legs never got sore before the lungs gave out so i never hadthis problem.
I would also recommend doing a couple hundred calf raises a day. Do them while watching tv. While cooking, doing dishes. Anytime you get a chance. the more you work it the more they can handle.
