Dumbbell Seated Biceps Curl (On Stability Ball)

Sit on a stability ball with a dumbbell in each hand. Place your feet shoulder-width apart for stability. Roll your shoulders back and down, maintaining a straight posture. Keep your elbows close to your torso and your palms facing forward. Exhale and curl the dumbbells up towards your shoulders, ensuring that only your forearms move. Pause for a second at the top of the movement, squeeze your biceps, and then inhale as you lower the dumbbells back down to the starting position. Repeat for the desired number of repetitions.
