update

[GottaGetBig]

Just wanted to give a little update i'm up to 190lbs now with very little fat gain. Once again this is all natural. My strength is up but the other day doing squat I hurt my back and can barely walk. Went to the chiropractor today and he said I should switch squat with leg press. Squat is prolly my favorite lift and IMO the most important one right now I'm doing 4 set of 10 the sets are warm up set with 225,345,385, and the 415, I'm pretty sure I have perfect form and I go a lil lower than parallel. Do any of you guys know what I should do. Should I lower the weight, keep doing the same weight or switch it with leg press. I've been doing squat since I was about 13 I'm 20 now and this is only like the second time I have really hurt my back. I may have just strained a lil to hard or wasn't quite warmed up. So any help would be great. Thanks in advance.

imho sets of 10 are too long for squats as the back will give out sooner than the legs.
