Hmmm....I wouldn't say screw warmups at all. First of all I'll say that since I've started warming up for ten minutes with an ancient heating pad, that I have gained a half inch in FSL, I was stuck at seven for the longest time. I have actuially modified it slightly, to where I actually sit on the pad under my balls, and will pull the pad over my johnson in between sets, because it is freakin cold in this damn house. It's made a difference. If you want a gain aid though, I would heat before and after your session of girth do an ice bath. Do a search and read the info, Blade and I put together some good info in that one. It's great for post workout healing, hang, gains, etc.
