Trapezius
Rotator cuff, Lower back

Rest your arms on the yoke, so that you are using the muscle to rotate, not hold the weight up.

Deadlift

Good mornings

Keep your chest up and bend over to almost 90 degrees.  Bend your knees slightly and go slow, do not bounce.  Use a moderate weight.

Back extension

Simply place your hips over the central support, anchoring the back of your ankles under the rear support. Allow your upper body to fall gently into the lower position, at about a 40-degree angle from horizontal. As you raise up, your back and legs should end as a straight line, legs through torso to head.
