A seated arm curl variation performed while balancing on a BOSU ball in a V-sit position, holding dumbbells in each hand. Sit on the BOSU ball with your feet off the floor and torso leaning slightly back to engage your core. With palms facing forward, curl the dumbbells toward your shoulders by flexing at the elbows, then lower them under control. This movement combines upper-arm strength work with balance and core activation for improved stability and muscular coordination.
