Seated Triceps Press

Sit on a bench with a straight back, feet flat on the floor, and back firmly against the bench. Grasp one end of a dumbbell with both hands (palms up) and raise it above your head, locking the elbows. With your elbows held in place and squared, slowly lower the dumbbell behind your head until you feel a stretch in your triceps. Press the weight back up, following a slight arc until the elbows lock and the weight is once again about your head
