dumbbell lying supine biceps curl

Lie flat on a bench with your back and head supported, and your feet flat on the ground.

Hold a dumbbell in each hand with your palms facing up 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.
