Sit on a bosu ball with your feet flat on the ground and your knees bent at a 90-degree angle. Hold a dumbbell in each hand with your palms facing forward and your arms fully extended down by your sides. Keeping your upper arms stationary, exhale and curl the weights while contracting your biceps. Continue to raise the dumbbells 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.
