Back and Shoulder Workout: Flex your back and shoulders by squeezing the FlexBar toward your mid-back.
Engage your chest by bending the FlexBar inward, similar to pectoral flywheels, providing resistance throughout your movement.
Perform curls with your biceps and forearms. Full resistance is provided all the way unlike dumbbells, giving you maximum resistance throughout the exercise.
