BUT, being that I am trying HST opposed to what everyone else says. I think I should seem some scientific evidence of some sort that shows that HST does work. I don't mean to come off as being an @$$ but I would really like to see some kind of writting that shows it works. I was in high hopes of this and was starting on my 2nd week of 10s and the more I told ppl about it the more discouraged I got by their negative attitudes towards HST. The wierd thing is, today was the first day I went back to working out the "old" way and I noticed that like HST, I only did 2 exercises per body part. I only did back, traps and shoulders. I might as well be doing HST, I just don't have the energy in the gym to stay in there for 2-3 hrs hitting every muscle from all angles. I eat very well in my diet but after abotu 45 mins of intense training I am ready to quit.
