How To Do

Sit upright on a stability ball with your feet flat, holding a dumbbell in one hand and resting that elbow on the inside of your thigh. Curl the dumbbell upward toward your shoulder, keeping your elbow stationary, then lower it back down with control. Focus on squeezing your biceps at the top of the movement.

Step-by-Step Instructions

Sit on a stability ball with your feet flat on the floor, shoulder-width apart, and your back straight. Hold a dumbbell in one hand with an underhand grip (palm facing up). Rest your elbow on the inside of your thigh on the same side as the arm holding the dumbbell.
Keep your other hand resting on your opposite thigh for balance and support.
Slowly curl the dumbbell upward by contracting your biceps, keeping your elbow stationary and close to your thigh. Exhale as you lift the weight.
Continue lifting until the dumbbell is at shoulder height or as far as your range of motion allows without moving your elbow.
Pause briefly at the top of the movement, squeezing your biceps.
Slowly lower the dumbbell back to the starting position while inhaling, fully extending your arm.
Repeat for the desired number of repetitions, then switch arms and repeat the exercise on the other side.
