THE MOVEMENT

Sit with the back straight, holding the bar across the back of the neck with an overhand grip:

• Inhale and extend the bar straight up, keeping the low back as straight as possible.

This exercise uses the deltoid, mainly the middle and posterior fibers, as well as the trapezius, triceps brachll, and serratus anterior. Although not worked as intensely, the rhomboids, infraspinatus, teres minor, and, deeper in, the supraspinatus also contract. You can also perform this exercise while standing at a frame that guides the barbell. Various specific machines can help with the performance of this exercise.

To prevent injury to the shoulder joint, which is vulnerable, lower the bar only as far as your unique shoulder structure and flexibility allow you to do comfortably.
