It's pretty cool man. I was pretty surprised. I took no measurements, but visually gained some good size, Especially in my legs and shoulders. I finished my first HST cycle about a week ago, and am now taking a week off. I think I'm going to work on strength for a while, then go back to HST. If you have any questions just ask. You can always get a good answer on the HST link in the training sticky.
