One-Arm Lying Rear Delt Fly Video Exercise Guide

The one-arm lying rear delt fly is a great exercise to assist you in building a complete set of shoulders as it targets the rear delts, an often lagging muscle for many lifters.

Strengthening the rear delts can lead to improved posture and a greater level of strength on other lifts.

Performing unilateral movements can help improve weaknesses, balance your strength and aesthetic physique, and work towards reducing injuries by addressing imbalances in the body.
