Hannah demonstrates the TRX Supinated Row TECHNIQUE: This movement is a great adaptation of the standard TRX mid row, by maintaining a supinated position this movement works the biceps as well as the back. ADVANTAGES: This movement is a great one to incorporate into an arm heavy workout, as it gives you the opportunity to work the back muscles as the primary mover. FAULTS: The main fault that can occur with this movement is allowing your core to cave giving your back and arch. The best way to fix this is to maintain an engaged core as well as draw shoulder blades in close together without shrugging shoulders. SCALING: This can be adapted by adjusting the angle at which the body is hanging to adjust the amount that the body is having to be pulled up.
