PRIMARY MUSCLES

Latissimus dorsi · Middle and lower trapezius · Rhomboids

SUPPORTING MUSCLES

Posterior deltoids · Biceps · Brachialis · Core stabilizers

Setup

  1. Use a stable hip hinge, seated position, or chest support as required while maintaining a neutral spine.
  2. Set the shoulder blades and align the wrists and forearms with the direction of the pull.
  3. Secure the feet or support points and choose a load that does not force torso rotation or swinging.

Execution

  1. Keep the torso angle fixed and pull the elbows toward the hips or lower ribs.
  2. Think about leading with the elbows instead of pulling only with the hands and biceps.
  3. At the top, keep the neck neutral and draw the shoulder blades back without compressing the lower back.
  4. Return to long arms for two to three seconds while retaining core and shoulder control.

Breathing

  • Inhale and brace before pulling while keeping the rib cage stable instead of overextending the lower back.
  • Exhale gradually as the elbows pull back or down, then inhale during the controlled return.

Common mistakes

  • The lower back rounds or overarches while torso momentum moves the load.
  • The elbows flare excessively or the load is pulled too high on the chest.
  • During a one-arm row, the rib cage and pelvis rotate instead of staying supported.
  • The return is dropped and the shoulder is jerked forward by the load.

Safety

  • Begin with a light load to confirm shoulder range, grip security, and equipment setup.
  • Maintain a neutral spine during hinges and rows; reduce the load immediately when torso swinging cannot be stopped.
  • Stop and seek qualified help for sharp pain, numbness, or weakness in the shoulders, elbows, wrists, or lower back.
