Smith Machine Sumo Romanian Deadlift
- Intermediate
- Machine
The Smith machine sumo Romanian deadlift combines a wide sumo stance with the hip-hinge mechanics of an RDL on a guided bar path. The wide stance turns the toes out and bias-loads the glutes and inner hamstrings, while the Smith bar removes the balance demand of a free barbell and locks the bar into a vertical line.
How to do the Smith Machine Sumo Romanian Deadlift
- Set the Smith bar to about mid-shin height and stand with feet wider than shoulders, toes turned out.
- Grip the bar with hands inside your knees and palms facing the body, then unrack by rotating the wrists.
- Stand tall with the bar against your thighs, brace your core, and pull your shoulder blades down.
- Hinge at the hips by pushing them back, letting the bar travel down the front of the legs.
- Stop when you feel a deep stretch in the glutes and hamstrings, with the bar at about mid-shin height.
- Drive the hips forward to stand back up to full lockout, squeezing the glutes hard at the top.

Why train it
- Bias-loads the glutes and inner hamstrings with a wide sumo stance.
- Allows safe heavy hinging on a guided bar path.
- Reinforces strong hip-hinge mechanics for lifters newer to the deadlift family.
Common mistakes
- Rounding the lower back as the bar lowers, which puts serious risk on the spine.
- Squatting the bar down instead of hinging back, which removes the glute-and-hamstring stretch.
- Letting the bar drift away from the body, which loads the lower back instead of the rear chain.
- Letting the knees cave inward, which strains the joint and loses the wide-stance bias.
