Dumbbell prone incline curl

Adjust the bench to a 45-degree incline. Lie face down on the bench with your chest and stomach resting against it. Hold a dumbbell in each hand with your palms facing down and your arms fully extended. Keeping 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. Repeat for the desired number of repetitions.
