With a dumbbell in each hand, stand with your arms hanging at your sides, and palms are facing each other. Keep your elbows locked into your sides. Your upper body and elbows should remain in the same place during the whole lift.
Keep your palms facing each other, curl the weight in your right hand up in a semi-circle toward your right shoulder. Squeeze the biceps hard at the top of the lift and then slowly lower. Do not turn your wrists during this lift! You can also do one arm at a time and/or alternate.
