Fixed rails hold both ends of the bar, so a one-arm pull here skips the tilt-and-swing balancing act that makes the Single Arm Barbell Row so awkward. What remains is anti-rotation work for your trunk plus a strict vertical path - hinge at the hips, take the center of the bar, and drive your elbow straight up.

How to do the Single Arm Smith Machine Row

  1. Adjust the height of the smith machine bar to waist level.
  2. Stand facing the smith machine with your feet shoulder-width apart.
  3. Bend your knees slightly and hinge forward at the hips, keeping your back straight.
  4. Grasp the bar with one hand using an overhand grip, with your palm facing down.
  5. Keep your elbow close to your body and pull the bar towards your waist, squeezing your shoulder blades together.
  6. Pause for a moment at the top of the movement, then slowly lower the bar back to the starting position.
  7. Repeat for the desired number of repetitions, then switch to the other arm.

Tip: Pause for a full count with the handle at your torso before letting it go back.

Muscles worked

Primary

Upper Back · Back

The rhomboids and mid traps squeeze the shoulder blades together at the end of each rep, which is where you should feel the strongest contraction.

Secondary

  • Biceps — The biceps bend the elbow on every row but should never be the muscle that fails first.
  • Forearms — Grip and forearm endurance often limit heavy rows, so use straps or a thicker grip if the hands give out before the back.

Common mistakes

  • Yanking with the arms — the rep should start with the shoulder blades pulling back, then the elbows follow; if the biceps give out first, you are curling the weight.
  • Torso heaving up — on bent-over rows the back angle should not change between reps; if it does, drop the weight.
  • Shrugging the shoulders up — pull the elbows back and down and keep the shoulders away from the ears, especially on face pulls.
  • Skipping the stretch — let the arms straighten fully and the shoulder blades slide forward at the start of each rep, then pull from there.

Where it fits in a workout

Rows are a main movement in any pull or back session and go before pulldowns and arm work. They pair well with a chest press or a push-up as a push and pull superset.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
