jeffhlewis, that's some good advice there. I don't want to commit to anything I won't stick to, I know there's a very real chance I could lose interest. I'm actually eating a lot of bacon right now, probably too much, and I can't quit steak and pizza, but I can add in some good stuff to balance out the occasional misdemeanor.
As for the shakes.. I can feel sore the next day, but it's not uncomfortable. /Maybe I'm not working out enough to warrant them?
From what a friend says he takes a 30s rest between sets, but I'll go to my absolute limit each time, and I literally can't go near the weights again for 5 minutes +. On my triceps (skullcrushers) yesterday, it got to the point where on my 4th set, I felt a sharp pain near my elbow that I was pretty sure was my tendon getting yanked,
so I tend to do muscle specific exercises in weights I can do around 10 reps with, but go until I can barely lift it (maintaining good form), sometimes taking like 6 or so seconds. This is what I understand to be the best way to increase mass.
