Hi My name's Dave (lke you couldn't tell ) and I've just come across this site. I'd really like to give this HST a try. I've been doing weights for a while now but am not making any size gains. I'm 20 years old, about 6'0, and weigh around 155lbs. I'd like to gain around 10-15lbs of mucsle so I'll weigh in around 165-170. I'm an ectomorph so do different training rules apply. Thanks in advance for replies.
