So just to let you guys know, this thread was meant as a review of the program, I didn't get a chance to finish but I still would say it's a very effective program, today was the girlfriends final week. She hit a 245 lb deadlift at a weight of 103. Which I believe is a 30 pound increase over 10 weeks. So from what I did an watching her, this program works, but is brutal, so don't take it lightly.
On another note, my back feels fine, I focused on my mobility and flexibility since I've been injured which worked wonders, I'm able to do the splits again (it's been years.) I hit a squat of 225x17 but haven't gone any heavier, will start back to something a bit heavier next week. Bench press is unaffected, hit 260x2. Pulled 225 sumo the other day with no pain. Going to slowly out more weight up, going to go sumo for a while too.
Thanks to everyone who gave me advice and sent me reading material.
