Even at low weight when I try to do lateral raises my shoulders feel really tight. I can do overhead press without pain, bench press without pain, rear delt raises without pain but I can't do lateral raises even at light weight. I've tried them standing, seated, one arm, two arms at a time and still same issue. Is there any other exercise I can use with free weights that'll isolate my lateral delts? I only have access to free weights since I have to workout at home. Should I just switch to scaptions?
