Mechanics

Pattern
horizontal pull
Equipment
dumbbells, bench
Geometry
150° Pull Pivot
Target feel
Lat stretches at the bottom; elbow drives back and up — not sideways.
Progression
Add load; switch to dead-stop from floor to eliminate momentum.
Regression
Chest-supported DB row removes lower back from the equation entirely.

Watch for

  • Rotating the torso to swing the weight up
  • Pulling to the chest instead of the hip
  • Rounding the support-side shoulder under load

Equipment context

Dumbbells allow a longer range of motion and independent arm movement, which can reveal side-to-side differences.
