At some point, just about every lifter gets some shoulder pain. It's often due to faulty biomechanics or weakness/inactivity of the scapular stabilizers. This exercise combination will help to activate and strengthen your scapular stabilizers.
Turkish get-ups (TGUs) require you to change your body position from lying down to standing up as you hold a weight up in the air. It recruits all of the scapular stabilizers at different points in the movement. Similarly, waiter's walks require the stabilizers to maintain scapular control as you walk with a weight above your head. Combining both of these exercises together sends the demand through the roof.
Try this combo as a warm-up before overhead pressing or use it as a finisher.
