Yeah I would say that I didn't have the best form on those SLDLs. I would figure it out half way through the set. Sorta like a golf swing, you got a whole lot of things going on at once and have to lock them all in at the same time.
I might actually lower my weight on that next week and focus on form. Don't want to get injured.
Where do you guys get your protein from for cheap? I see its $53 for 5 lbs of ON Whey on Amazon. Is there anything better than that?
