Hi everyone! First of all im new to the site and would like to say hello to everyone here, my names scott mont im from ellesmere port (just outside liverpool,uk). Im almost 21 and have been lifting since i was 16. not to sure on height/weight at this time but will update shortly. Anyway ive been doing a typical 3x week back/bi, chest/tri & delt/legs routine but i am oing to convert to HST ! I have a few questions and wondered if you guys could help me out. Do i only include iso's for bi's n tri's etc. in the 10's & 5's and use only 12 compounds for the 15's? Do you use 1x15, 2x10 & 3x5? Why do people say to switch between deads and squats? I thought deads were for back and squats are for legs? And finally I struggle with chin ups so are pulldowns ok until i can do chin ups? also, which rows are better Bent Over Barbell or T-Bar? Any help from you guys is appreciated as i am really excited about using HST, Thanks again, Mont.
