if one decides to begin lifting heavy, but keeping volume commiserately low with the upper poundage, will this impede GH release? i would gather that it could. the sytem is under less stress overall, the duration is not long, and like alactic trainng the muscles are never exhausted. but I havn't any practical experience. second any recommendations for an excersize to increase verticle leap? thank you in advance for responses.
