How to do it
Anchor the TRX and stand facing sideways to it, gripping one handle with your elbow bent 90 degrees and tucked against your side. Lean away to load the strap, then rotate your forearm outward away from your body while keeping your elbow pinned to your waist. Return to the start with control as the strap resists the motion. Finish your reps, then turn around to train the other arm.

Common mistakes
