To perform a One Arm TRX Pull, adjust the TRX straps to a height where your arm can fully extend while holding onto the handle. Stand facing the anchor point, leaning back slightly with your arm extended in front of you, palm facing inward. Engage your back muscles as you pull your body towards the handle, focusing on squeezing your shoulder blade towards your spine. Lower yourself back to the starting position with control. Repeat for desired reps, then switch sides. This exercise targets the back muscles, particularly the latissimus dorsi and rhomboids, while also engaging the biceps and core for stability.
