Use this move on a shoulder or back day. It works best with light weight and slow, clean reps.
What Is The Point of the Bent Over Rear Delt Fly Head on Bench?
The bent over rear delt fly head on bench exercise builds strong rear deltoids and improves shoulder stability. It fixes forward shoulder posture from too much pressing.
How To Do The Bent Over Rear Delt Fly Head on Bench
- Set an incline bench to about 30 to 45 degrees and lie face down with your chest against the pad, so the bench supports your torso and your head rests near the top. This removes any temptation to use body swing.
- Grab a dumbbell in each hand and let your arms hang straight down, palms facing each other. Plant your feet for a little stability and brace your core.
- Set both shoulder blades down and slightly back before you move. Starting from the mid-back is what puts the load on the rear delts instead of the traps.
- Keep a soft, fixed bend in your elbows, around 10 to 20 degrees, and hold it for the whole set. A locked elbow angle keeps this a fly and not a row.
- Lift the dumbbells out to your sides in a wide arc, leading with your elbows and pinching your shoulder blades together. Picture your arms sweeping out like wings.
- Raise the weights until your arms are roughly parallel to the floor and level with your shoulders. Stop there rather than heaving them higher into the traps.
- Pause and squeeze the rear delts and mid-back at the top for a beat. Feel the muscles between and behind your shoulders working hard.
- Lower the dumbbells slowly back down under control over 2 to 3 seconds. Use light to moderate weight for 12 to 15 reps across 3 sets, since the rear delts reward control over load.
Bent Over Rear Delt Fly Head on Bench Form Tips
- Keep your chest pressed to the pad the whole time.
- Keep a soft bend in your elbows. Do not lock them.
- Lift the weights out to the sides in a wide arc.
- Raise your arms only until they are level with the floor.
- Lead the lift with your elbows, not your hands.
- Squeeze your shoulder blades together at the top.
- Move slow and with control. Do not swing.
- Breathe out as you lift. Breathe in as you lower.
- Keep your neck long and your eyes down.
Common Mistakes to Avoid for the Bent Over Rear Delt Fly Head on Bench
- Bending the elbows and rowing the weights up. When the elbows close, the lats and biceps jump in and the rear delts get an easy ride. Fix a soft bend in the elbow and keep it constant so the movement stays a fly.
- Going too heavy for such a small muscle. Heavy dumbbells force swing and bring in bigger back muscles that hide the rear delt. Use a light load you can control for clean, high reps and let the rear delt do the work.
- Shrugging the shoulders up toward your ears. Hiking the shoulders hands the job to the upper traps and shuts the rear delts out. Keep the shoulder blades set down and lead with the elbows out to the sides.
- Lifting the weights well past parallel. Raising the arms above shoulder level rolls the load onto the traps and can pinch the joint. Stop at about parallel where the rear delt peaks and hold there.
- Failing to set the shoulder blades before pulling. Starting loose lets the shoulder joint do work the mid-back should own. Retract and depress the blades first, then arc the weights up from that set position.
- Dropping the dumbbells fast on the way down. A quick descent throws away the eccentric, which builds a lot of the muscle. Lower over 2 to 3 seconds and keep the rear delts under tension the whole way.
- Arching up off the pad to swing the weights. Peeling your chest off the bench brings back the momentum the bench was meant to remove. Keep your chest pinned to the pad so only your arms move.
- Craning your neck up to look ahead. Lifting the head strains the neck and pulls the spine out of line. Keep your gaze down and let your head rest in line with your body.
- Rushing past the top without squeezing. Skipping the peak contraction misses where the rear delt works hardest. Pause and pinch the shoulder blades together for a beat on every rep.
- Letting the palms rotate so it becomes a lateral raise. Turning the wrists changes the muscle emphasis and can strain the shoulder. Keep the palms facing each other or thumbs slightly up for the cleanest rear delt hit.
- Holding your breath through the set. A held breath weakens your brace and makes you unstable even on a supported bench. Breathe steadily and keep light core tension throughout.
Bent Over Rear Delt Fly Head on Bench Workout Tips
- Let the bench do its job by keeping your chest glued to the pad. The support removes body swing so the rear delts have to move the weight alone.
- Set the shoulder blades down and back before every rep, then lead with your elbows. Starting from the mid-back is what targets the rear delts instead of the traps.
- Keep a soft, fixed elbow bend the whole set. That one rule keeps the movement a fly rather than sliding into a row.
- Use light weight and reps in the 12 to 15 range. The rear delt is small and grows best with control and a good pump, not heavy loads.
- Chase the mind-muscle connection by thinking about squeezing the space between your shoulder blades. Feeling the target muscle is the best way to build a stubborn area.
- Pause and squeeze hard at the top for a beat. The peak contraction is where the rear delts and mid-back work the most.
- Control the descent over 2 to 3 seconds. The slow eccentric keeps tension on the muscle and drives extra growth.
- Program rear delt flies after your heavy presses and rows as a finisher. Rear delts are chronically underworked and need dedicated volume.
- Try turning your thumbs slightly up at the top to deepen the rear delt squeeze. That small external rotation can sharpen the contraction.
- Stop at parallel rather than swinging higher into the traps. Keeping the arms level with the shoulders keeps the rear delt in charge.
- Strong rear delts balance out all your pressing and improve shoulder health and posture. Most lifters carry a big front-to-back imbalance.
- Film a set from the side to check for a sneaky rowing motion. Video catches elbow bend that is hard to feel in the moment.
- Set the bench a touch higher if the weights hit the floor at the bottom. A steeper angle gives your arms room to hang and stretch.
- Progress with tiny weight jumps or an extra rep or two. Small muscles do not need big leaps to keep improving.
- Pair rear delt work with rotator cuff exercises for a bulletproof shoulder. Both protect the joint from years of pressing.
- Be patient and consistent, since rear delts are slow to respond. Steady strict volume over months is what finally brings them up.
