Proper positioning of your arm on the bench is crucial in order to execute this movement safely and effectively. You should avoid placing your elbow on the very end of the bench since this will cause issues with your tendons and ligaments along with placing too much unneeded stress on the elbow joint. Tuck your armpit into the end of the bench and lay your arm flat on the bench pad.
