Exercise guide

Ring Single Arm Rear Delt Row

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Shoulders

This unilateral movement isolates the posterior deltoid and upper back while challenging core stability to prevent torso rotation. It is highly effective for correcting muscle imbalances and improving shoulder health through controlled, single-arm pulling.

Equipment

Setup

  1. Set one ring to approximately waist height and grasp it with one hand using a neutral or overhand grip.
  2. Walk your feet forward to create a diagonal lean, keeping your body in a straight line from head to heels.
  3. Place your non-working hand on your hip or across your chest to ensure it does not assist the movement.
  4. Square your shoulders and hips toward the anchor point, engaging your core and glutes to stabilize the spine.

How to do it

  1. Exhale as you pull your body toward the ring by driving your elbow back and slightly outward at a 45 to 60-degree angle from the torso.
  2. Focus on pulling with the back of the shoulder, stopping when your hand is level with your chest and your elbow is past your midline.
  3. Inhale as you slowly lower yourself back to the starting position with a controlled 3-second eccentric phase.
  4. Complete all reps on one side before switching to the other to maintain consistent tension.

Form checklist

  • Keep your shoulders square; do not let the working shoulder dip or the torso rotate toward the ring.
  • Maintain a 'high' elbow path to emphasize the rear deltoid and trapezius over the latissimus dorsi.
  • Keep your core braced and glutes squeezed to prevent the hips from sagging or the back from arching.
  • Ensure the wrist remains neutral and does not curl inward during the pull.

Pro tips

  • Imagine pulling your elbow 'out and back' rather than just 'up' to maximize posterior deltoid recruitment.
  • Pause for one second at the peak of the contraction, focusing on squeezing the shoulder blade toward the spine.
  • Initiate the movement by retracting the scapula slightly before the arm begins to bend.

Make it harder

  • Walk your feet further forward toward the anchor point to create a more horizontal body angle, increasing the resistance.
  • Elevate your feet on a box or bench to perform the row from a deficit, significantly increasing the load on the upper back.
