Starting Position
Standing with knees slightly bent and back straight. Hold a dumbbell in each hand, in a neutral grip along the body.
Execution
While maintaining a steady upper body, raise a dumbbell by bending from the elbow. Keep your hand in a neutral grip (hence the name hammer grip). Squeeze your biceps, then slowly return to the initial position. Keep your elbow close to your body during the whole movement. Repeat for desidered repetitions before doing the same for the other arm.
An easier variation would be to alternate this movement one arm after the other.
A harder variation would be to perform this movement with both arms at the same time.
