Technique Stand with your left or right shoulder pointing in the same direction as the TRX anchor point. Have your arms straight out in front of you with the bar horizontal. Using your arms, rotate the bar from a horizontal position to a vertical position and back. Advantages This movement works your transverse abdominis as well as the muscles surrounding your shoulder girdle making a great compound exercise. Faults The most common fault with this is not having your arms completely locked out and even using lateral flexion and twisting (of the torso) to do the movement. Scales To scale this move up and down you change the position of the hand that is pushing the bar up. The closer to the middle you position your hand, the harder it becomes. You can also move closer and further away from the anchor point. The closer the anchor point to begin with, the easier and vice versa.
