As in the link that UT posted they will not harm, and may not help either. That being said, why can't we agree to disagree…if calf raises work for jumperuk, and not for ut then thats the answer. Remember not everyone is going to use the same program…and even if the calf raises may have a placebo effect…it's still working. And as the saying goes if it's not broke don't try and fix it…7.54 from under a full approach is not broke by any means.
UK, were you at the Princeton meet last weekend?
