When I train Back and Bi's the Time I get to Bi's there done, last week I hit an awesome Back workout and then went to do bi's and they felt fresh, It was awesome to hit them hard! Even at the end of my workout I still wanted to lift! Results are What I WANT from a Product and with RESULTS thats what I'm Getting!
