Performing the: A Step-by-Step Tutorial Brachialis
Stand up straight with a dumbbell in each hand, arms fully extended, and palms facing your torso. This will be your starting position.
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 moment as you squeeze your biceps.
Then inhale and slowly begin to lower the dumbbells back to the starting position.
Repeat this motion for the recommended amount of repetitions. Ensure your elbows stay close to your torso at all times and do not use your back or shoulders to lift the weights; your biceps should do all the work.
