I have trouble getting 40lb and over db over my left shoulder. With 40lb+ db, I have to do the thigh kick to get it over shoulder and then raise it straight up. For some reason I cant just have it rest on the shoulder and start the exercise (however, I can do this in between reps) So I can do 5x5 with good range of motion (db to eye level) with the 40 db and 3x10x35, yet I can almost never get the 42.5 db up on my left side. (even with thigh kick) Should I stick with lower weights or am I doing something wrong? I hope this make sense. edit: forgot to mention I do seated military press.
