Performing the: A Step-by-Step Tutorial Dumbbell Peacher Hammer Curl
Keep your upper arms stationary, exhale and curl the weights while contracting your biceps. Continue to raise the weights until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a brief pause as you squeeze your biceps.
Inhale and slowly begin to lower the dumbbells back to the starting position.
Keep your elbows close to your torso at all times. Do not use your back or shoulders to lift the weights; your hands should do all the work.
Repeat the movement for the recommended amount of repetitions.
