Kettlebell Prone Rear Delt Swing
- Intermediate
- Isolation
- Rep-based

- Shoulders
The Kettlebell Prone Rear Delt Swing isolates the posterior deltoid and mid-trapezius by using an incline bench to eliminate momentum and provide a stable base for unilateral tension. This variation is excellent for correcting postural imbalances and building thickness in the upper back.

Setup
- Set an incline bench to a 30-45 degree angle.
- Lie chest-down on the bench with your feet firmly planted on the floor for stability.
- Grasp a kettlebell in one hand with a neutral grip (palm facing inward), letting the arm hang straight down.
- Start with your non-dominant side to identify and address strength imbalances.
How to do it
- Exhale and swing the kettlebell outward and slightly back in a wide arc, keeping only a slight bend in the elbow.
- Raise the weight until your arm is roughly parallel to the floor, focusing on the contraction in the back of the shoulder.
- Inhale and control the kettlebell on the descent, maintaining tension throughout the eccentric phase.
- Perform the movement with a rhythmic, controlled tempo, avoiding any 'jerking' at the bottom of the swing.
Form checklist
- Keep your chest pressed firmly against the bench to prevent torso rotation.
- Maintain a neutral neck position by looking slightly down at the floor.
- Ensure the movement comes from the shoulder joint, not by swinging the torso.
- Keep the wrist straight and firm throughout the entire range of motion.
Pro tips
- Focus on 'pushing' the kettlebell away from your body toward the side wall to maximize rear delt recruitment.
- Use a 'pinky-up' hand orientation at the top of the movement to further isolate the posterior fibers of the deltoid.
- Pause for a fraction of a second at the peak of the swing to emphasize the mind-muscle connection.
Make it harder
- Add a 2-second isometric hold at the top of every repetition to increase time under tension.
- Slow down the eccentric (lowering) phase to a 3-count to challenge the muscle's stability.
