Rear delts are the most under-developed part of the shoulder for most lifters. The pressing-heavy emphasis of typical training programs hits the front delts repeatedly while leaving the rear delts mostly untrained. The result is the imbalanced, forward-rounded shoulder appearance that most lifters carry, along with the chronic shoulder issues that come from front-rear delt imbalances. The best rear delt exercises address this directly with focused isolation and rowing variations that target the muscle through its primary horizontal abduction function.
Below are ten effective rear delt exercises that cover bent-over flies, cable variations, suspension trainer work, and unilateral isolation work. Together they form a complete rear delt training program that produces both visible muscle development and the postural improvements that come from balanced shoulder training.
Dumbbell Seated Bent Over Alternate Rear Delt Fly
The Dumbbell Seated Bent Over Alternate Rear Delt Fly sits on a bench with the chest leaning forward toward the thighs and performs alternating fly motions with light dumbbells. The seated bent-over position isolates the rear delts directly through their primary horizontal abduction function.
For direct rear delt training, the seated bent-over fly is one of the most effective single exercises that exists. The chest-supported position eliminates body sway and forces the rear delts to do all the work, which produces stronger isolation than standing variations. Run it for 3 to 4 sets of 12 to 15 reps with light weight.
Sit on a bench with the chest resting forward toward the thighs. Hold light dumbbells with arms hanging down, palms facing each other. Lift one dumbbell out to the side until the arm is parallel to the floor, squeezing the rear delt at the top. Lower under control. Alternate sides on each rep.
Bar Band Bent Over Rear Delt Fly
The Bar Band Bent Over Rear Delt Fly attaches a resistance band to a low anchor (or grips it underfoot) and performs a bent-over fly with the band as the resistance. The band tension increases through the rep, which loads the contracted rear delt position more heavily than dumbbells alone.
For at-home rear delt training, the band variation produces stronger contraction than free-weight flies because the tension peaks at the top of the rep when the rear delt is most contracted. Use it as the primary rear delt exercise in any band-only program or as variety in dumbbell-based programming.
Step on the resistance band with both feet to anchor it. Hinge over with a flat back, holding the band handles or ends in each hand. Pull the hands out to the sides in a fly motion, squeezing the rear delts at the top. Lower under control.
Rear Deltoid Stretch
The Rear Deltoid Stretch reaches one arm across the body and uses the opposite hand to pull it closer to the chest. The position stretches the rear delt and the back of the shoulder capsule.
Rear delt training requires both strength work and mobility work. Tight rear delts limit the range of motion during fly exercises, which reduces the effective stretch and contraction. The stretch is a daily habit for 60 to 90 seconds per side that complements direct strength training.
Stand or sit tall. Reach one arm across the body at chest height. Use the opposite hand to pull the arm closer to the chest, feeling the stretch in the back of the shoulder. Hold for 60 to 90 seconds per side. Switch sides and repeat.
Dumbbell Seated Bent Over Rear Delt Row
The Dumbbell Seated Bent Over Rear Delt Row sits on a bench with the chest leaning forward and rows the dumbbells with elbows flared wide rather than tucked close to the body. The flared-elbow position emphasizes the rear delts and upper back rather than the lats.
For lifters who want both strength and isolation work for the rear delts, the bent-over row variation adds heavier loading than fly exercises while still emphasizing the rear delt through the wide-elbow path. Run it for 3 sets of 10 to 12 reps as a strength-focused rear delt exercise.
Sit on a bench with the chest resting forward toward the thighs. Hold dumbbells with arms hanging down. Pull the dumbbells out and up to the sides with elbows flared wide, squeezing the rear delts and upper back. Lower under control. Keep the elbows higher than the wrists throughout.
Cable Seated Rear Delt Fly with Chest Support
The Cable Seated Rear Delt Fly with Chest Support uses a chest-supported seated position with cables anchored at the appropriate height. The chest support eliminates body sway entirely and the cables provide constant tension throughout the rep, producing one of the strictest possible rear delt exercises.
For lifters with cable access, the chest-supported cable fly is the gold standard rear delt exercise. The combination of chest support, constant cable tension, and pure isolation produces stronger rear delt development per set than nearly any other rear delt exercise. Run it for 3 to 4 sets of 12 to 15 reps.
Set up at a cable station with handles at chest height when seated. Sit with the chest pad supporting the upper body. Grip the handles with arms extended forward. Pull the handles out to the sides in a fly motion, squeezing the rear delts at the back. Lower under control.
Dumbbell Lying One Arm Deltoid Rear
The Dumbbell Lying One Arm Deltoid Rear lies on the side and performs a single-arm rear delt raise with a light dumbbell. The lying position eliminates body sway and isolates the rear delt of the working arm directly.
The single-arm lying variation is one of the most isolated rear delt exercises that exists. The lateral position removes any possible body compensation and forces pure rear delt work. Use it as a finisher after primary rear delt work to fully exhaust the muscle.
Lie on the side with the bottom arm supporting the head. Hold a light dumbbell in the top hand with the arm extended down. Lift the dumbbell up and back in a rear delt raise motion until the arm is roughly parallel to the floor. Lower under control. Switch sides.
Rear Delt Fly with Bed Sheet
The Rear Delt Fly with Bed Sheet uses a folded bed sheet (or towel) anchored to a door or sturdy surface and performs the fly motion with the sheet providing isometric resistance. The improvised setup produces strong rear delt loading without any equipment beyond what most homes already have.
For travelers and lifters in extremely minimal-equipment situations, the bed sheet variation produces real rear delt loading without specialized gear. The tensile strength of folded fabric provides plenty of resistance for high-rep rear delt work. Run it for 3 sets of 15 to 20 reps as the primary rear delt exercise when no equipment is available.
Anchor a folded bed sheet to a sturdy door at chest height. Stand facing away from the door with the sheet ends in each hand. Pull the hands out to the sides in a fly motion, working against the tension of the sheet. Lower under control.
Suspender Rear Delt Row
The Suspender Rear Delt Row uses a suspension trainer (TRX or rings) anchored overhead and performs an inverted row with elbows flared wide to emphasize the rear delts. The body angle determines the load: more horizontal positions produce harder reps.
For bodyweight rear delt work, the suspension trainer row is the most effective option that exists. The flared-elbow path emphasizes the rear delts and upper back rather than the lats, and the bodyweight loading provides consistent resistance throughout the rep. Adjust difficulty by changing the body angle.
Set up a suspension trainer with handles at roughly waist height. Lean back with the body straight, gripping the handles. Pull the body up by driving the elbows out to the sides (not down to the body), squeezing the rear delts at the top. Lower under control.
Dumbbell Prone Rear Delt Swing
The Dumbbell Prone Rear Delt Swing lies face-down on an incline bench and performs a rear delt fly with one arm at a time, swinging the dumbbell up and back with controlled momentum. The prone position eliminates body sway and the swing pattern adds slight power-development to the strength work.
For variety in rear delt training, the swing variation produces different muscle recruitment than strict isometric flies. The slightly higher tempo and momentum-based loading produces stronger neural activation, which can break through plateaus that strict-form rear delt work creates over time.
Lie face-down on an incline bench set to roughly 45 degrees. Hold a dumbbell in one hand with the arm hanging straight down. Swing the dumbbell up and back, leading with the elbow, until the arm is parallel to the floor. Lower under control. Switch sides on each set.
Dumbbell Rear Delt Raise
The Dumbbell Rear Delt Raise stands tall with light dumbbells held at the front of the body and raises them back behind the body in a reverse fly motion. The standing variation allows quick set-ups and easy load changes.
For lifters who want a quick rear delt finisher between heavier sets, the standing rear delt raise fills the role efficiently. The standing position allows fast transitions between sets and the upright posture makes the exercise accessible to lifters who struggle with bent-over positions. Run it for 3 sets of 12 to 15 reps as accessory work.
Stand tall with light dumbbells held at the front of the thighs. Raise both dumbbells back and out to the sides in a reverse fly motion, ending with the arms parallel to the floor and behind the body. Lower under control.
How To Program These Workouts
A productive rear delt session pulls four to six exercises from the list above. A balanced session includes one bent-over fly variation (seated bent-over alternate fly or band fly), one rowing exercise (bent-over rear delt row), one isolated finisher (lying one-arm rear or rear delt raise), and one stretch (rear deltoid stretch). Run isolation exercises for 3 to 4 sets of 12 to 15 reps with light weight; rowing for 3 sets of 10 to 12 reps with moderate weight.
Train rear delts two to three times per week. The rear delts recover within 24 to 48 hours of moderate training, and frequent training drives faster growth than once-weekly heavy sessions. Most lifters program rear delt work on shoulder day or back day; pairing rear delt isolation with back compounds (rows, pulldowns) produces strong combined upper-back development.

Final Thoughts
The best rear delt exercises produce visible muscle development and balanced shoulder appearance through focused isolation work that pressing exercises miss. The combination of fly variations, rowing patterns, and unilateral isolation covers the rear delts from multiple angles, which produces fuller, more complete shoulder development than pressing-heavy programs achieve.
Stay focused on form and weight selection. The most common rear delt training mistake is using weight that is too heavy and turning the exercise into a body-swing momentum lift. Light weight done with strict form and a 1 to 2-second peak contraction produces stronger rear delt development than heavy weight done with body sway. Most lifters need to use weights significantly lighter than they expect; that is normal for rear delt work.
Frequently Asked Questions
How heavy should I go for rear delt exercises?
Most lifters work with 5 to 15-pound dumbbells for fly variations and 10 to 25-pound dumbbells for rowing exercises. The right weight is whatever allows clean reps with strict form (no body sway) and a strong peak contraction. Heavier weight that requires momentum to lift produces less rear delt development than light weight done with strict form.
How often should I train rear delts?
Two to three times per week works for most lifters. The rear delts recover within 24 to 48 hours of moderate training, and frequent training produces faster growth than once-weekly sessions. Most lifters program rear delt work as accessory exercises on shoulder day or back day rather than as a standalone training day.
Why are my rear delts so weak?
Most lifters under-train rear delts severely compared to other muscle groups. Pressing-heavy programs hit the front delts repeatedly while leaving the rear delts mostly untouched. The fix is direct, focused rear delt work two to three times per week with appropriate volume (8 to 12 weekly sets). Most lifters see noticeable rear delt growth within 8 to 12 weeks of consistent training.
Do I need cable machines for rear delts?
No, but cables produce stronger rear delt loading than free weights through constant tension. For lifters with cable access, the cable rear delt fly is the most effective rear delt exercise. For home lifters, dumbbell flies, band flies, and suspension trainer rows produce real rear delt development without specialized equipment.
Can rear delt training fix forward-rounded shoulders?
Partially yes. Forward-rounded shoulder posture comes from a combination of weak rear delts, tight chest, and weak upper back. Rear delt training addresses the weakness component, which produces meaningful posture improvements over 8 to 12 weeks. Combining rear delt training with chest stretching and upper-back rowing work produces faster, more complete posture corrections.
