Performing the: A Step-by-Step Tutorial Dumbbell One Arm Seated Hammer Curl
Position your elbow against your inner thigh, with your arm fully extended and the palm of your hand facing your torso; this is your starting position.
Slowly curl the weight while keeping the upper arm stationary, continue to raise the weight until your biceps are fully contracted and the dumbbell is at shoulder level.
Hold the contracted position for a brief moment as you squeeze your biceps.
Gradually begin to bring the dumbbell back to the original position, fully extending your arm and inhaling as you perform this step. Repeat the exercise as necessary, then switch to the other arm.
