Dumbbell Bicep Curl
Stand straight up,with your head up and your legs straight. Start with the dumbbells at arm's length with your palms facing in. Curl dumbbells up at the same time,twising your wrists on the way up. Your palms should be facing up when you are at the end of the movement. Do NOT swing and do NOT move your elbows. They should stay in the same place during the whole movement. Keep your arms close to your side.
