Ok, I currently have a problem with my elbow (trapped or pinched nerve I think, I'm seeing the doc about it on Tuesday) which prevents me from squatting properly. I also can't do lunges, and any other squat where I have to hold the bar with bent arms. It causes me pain (as my elbow is bent throughout the set) and eventually my arm goes numb to the point I can no longer hold the bar. Front and hack squats are ok, so I'll be doing them. I was wondering, is it worth using any machines while I can't full squat? Leg press, leg extension, hamstring curl... whatever, would any of them be any good for now? Other exercises which are effected are chins, any sort of rows, and pull-downs (I can DL and do pushing movements without problem) but not to the extent that it prevents me from doing them (although with slightly restricted ROM). I really don't want to miss out on working my legs, so any help would be gratefully received. Thanks.
