I just made the permanent switch from back squats to front squats as my primary squat. Less spinal compression, easier to go deep and therefore is easier on the knees (I've had some problems with my left knee). So the only problem is that my wrists hurt like hell after I rack the bar. They get hyperextended way too much, and I'm worried that maybe it isn't safe. Am I doing something wrong, or would you suggest using straps? I try to keep my elbows up but I think I'm just too inflexible.
