Yea I have some pretty defined calves already. I felxed them one day for my therapist (he is also the therapist for many pro athletes including the dolphins and titans last year) He said he had never seen calves like mine. Mine arent huge but they are pretty cut. My training partner is alwyas trying to get bigger calves. He did some calf exercises during the season and had problems running. I dont think it is really worth it imo.
ONe season I did them once a week though the whole season. I also ran my PR that season. But I love deads.
