@elizabethgracefit: Why are rear delts important to train? If your goal is a 3D back, you need to be training your rear delts too! They attach your upper back and shoulders so when built, it helps back look thicker and 3D! Face pulls, rear delt fly machine and cable rear delt fly are great exercises for this! @DFYNE dc ELIZABETH #GymTok #fitnesstips #backtraining #backworkout #reardelt
