Dumbbell One Arm Reverse Fly (with Support)

Bracing against a bench or support while doing a one-arm reverse fly removes torso sway, isolating the rear delt on the working side without any assistance from momentum. Training unilaterally also exposes rear delt imbalances that are common given how asymmetrically people use their dominant arm day to day. Light weight and a controlled squeeze at the top matter more than load here.
