Step by step
- Place one hand on a stable bench, step back, and hinge forward with a neutral spine.
- Hold the dumbbell in the other hand and bring that upper arm beside the torso with the elbow bent about 90 degrees.
- Keep the upper arm still as you straighten the elbow and move the dumbbell behind you.
- Pause briefly, then bend the elbow slowly before repeating and changing sides.
Common mistakes
- Swinging the entire arm from the shoulder instead of moving at the elbow.
- Rounding or rotating the torso as the dumbbell moves backward.
