I have hit a wall in my training. I am 19yrs old and stuck at 175 with about 8-9 % bf. I have not been gaining weight at all during spring. So i switched to a powerlifting routine which isn't helping much either. The routine is 3 days a week with a core exercise such as deadlifts squats and bench on each day. For my core exercise i do about 8 sets while while going up in weight as i go down in reps. One isolation exercise for bicepts, no direct caft, tri, or shoulder work. After the core exercise i do about 2-3 more exercises 4 sets of each. I am not responding too well to this type of training. So i decided to switch to HST traing because i think i will respond very well to this training. I read up on it but i am not sure how i decrease the reps, is it every week or every 2 weeks? I just need someone to help break it down for me. Or if anyone has any input for me i would appreciate it. I have been training for about 4 years. Even though i weight 175 i look like i weight 185. I have a good diet, and the main reason why i decided to try something different is that i cannot get my arms to grow, and my muscle's feel flat alot of the time. If i felt my training was not lacking i would be entering in a local BB show in the teen division because the promoter wants me to, but i feel and i think i look like shit so i could use some help. Thanks
