|Utility:||Basic or Auxiliary|
Sit on seat with back support just below shoulder height. Position dumbbell overhead with arm straight up or slightly back.
Lower dumbbell behind neck or shoulder while maintaining upper arm's vertical position throughout exercise. Extend arm until straight. Return and repeat. Continue with opposite arm.
Let dumbbell pull back arm slightly to maintain full shoulder flexion. Keep elbow in so movement does not resemble overhead press. Back support should not be so high that it interferes with dumbbell being completely lowered (ie: full range of motion). See rear view. Exercise may be performed on bench without back support.
