In terms of size gains with this program, I'd say I've put on around 12-14 pounds in about 10-11 weeks. I have gained some fat. Not extradinairy amounts, but I am a little thicker.
One thing I'm noticing now, and I dunno why because DF pretty much had the same lifts, but I'm finding that my core is getting much stronger.
I dunno though, maybe it isnt necessarily SF training that's doing it for me but just an overall improvements on the techinque of all my lifts. I say this because I have been REALLY focusing on doing them all right. Specifically barbell rows (parallel to floor), chins and deads. I was already decent with chins and deads, but I wasn't activating my lats as much as I could have. Now I am, and the increase in strength in my lats is also carrying over to other lifts such as Bench Press. In bench, I have a lot more stability and control when going downwards which is really key for me because I can put out that much more energy when I drive it back up.
However, my lower back DOES feel pretty taxed from it all.
I know I've gained size in my delts, lats and traps especially. Of all the muscle groups, those are the ones that I am sure have grown because I can see and feel a difference.
I dont have my numbers here right now as I left my training bag in my locker at the gym. So hold up if you really want them.
Oh, and my weight now is 226 and I started at 213. I'm also 6'2.
