The one arm barbell press is performed by holding a barbell with one arm with your palms facing you or each other and pressing the bar up in one powerful movement. You can either perform this movement in a lying position on a bench or as a standing shoulder press, which will determine the optimal type of grip.

Single-arm standing shoulder press Instructions Grab a dumbbell and either sit on a military press bench or a utility bench that has a back support on it as you place the dumbbells upright on top of your thighs or stand up straight. Clean the dumbbell up to bring it to shoulder height.
