The dumbbell one arm row with rack support is a single-arm pulling exercise that primarily builds the lats (latissimus dorsi), along with the teres major and minor, infraspinatus, and the middle and lower trapezius. Bracing your free hand on a power rack upright instead of a bench gives a stable, joint-friendly setup for rowing one dumbbell to your hip — useful for fixing left-to-right strength imbalances and building back thickness.
Cómo hacer el Dumbbell One Arm Row (rack support)
- 1Set a dumbbell on the floor beside a power rack upright. Stand to the side and grip the upright at roughly waist height with your non-working hand.
- 2Step your feet back and hinge forward at the hips until your torso is roughly parallel to the floor, keeping a flat back and a soft bend in your knees.
- 3Brace against the upright with your supporting arm to lock your torso steady, then reach down and grip the dumbbell with your working hand, palm facing in.
- 4Pull your shoulder blade down and back, then row the dumbbell up toward your hip and lower ribs, driving your elbow back close to your body.
- 5Squeeze your back at the top with the elbow above the line of your torso, keeping your wrist neutral and your shoulder away from your ear.
- 6Lower the dumbbell under control until your arm is fully extended and you feel a stretch across the lat.
- 7Complete all reps on one side, then switch your grip and stance to work the other arm.
- 8Set the dumbbell down on the floor with control to finish the set.
Consejos de técnica
- Keep your torso fixed and let the back do the work — avoid twisting or rotating your trunk to swing the weight up.
- Lead the pull with your elbow rather than your hand to keep tension on the lat and mid-back instead of the biceps.
- Brace firmly through the supporting arm and keep your hips square to the floor so both sides of your back stay level.
- Use a full range of motion: a complete stretch at the bottom and a hard squeeze at the top builds more muscle than short, fast reps.
- Keep your neck in line with your spine — look at the floor a short distance ahead rather than craning your head up.
Errores comunes
- Yanking the dumbbell up with body english and momentum, which shifts load off the lat and strains the lower back.
- Rounding the upper back during the row, which removes tension from the target muscles and risks the spine under load.
- Shrugging the shoulder toward the ear at the top, which turns the movement into an upper-trap shrug instead of a back row.
- Cutting the range of motion short by not lowering the dumbbell fully, which trains only the easy middle of the lift.
- Letting the working shoulder roll forward at the bottom instead of staying packed, which stresses the shoulder joint.
Preguntas frecuentes
What muscles does the dumbbell one arm row with rack support work?
It primarily targets the lats (latissimus dorsi), teres major and minor, infraspinatus, and the middle and lower trapezius. The brachialis, brachioradialis, rear deltoid, and lower chest assist as synergists.
Why brace on a rack instead of a bench?
Gripping a power rack upright lets you set a comfortable torso height and gives a solid anchor for your supporting arm, so you can stay rigid and focus on rowing rather than balancing on a bench.
How many sets and reps should I do?
For back size and strength, 3–4 sets of 8–12 reps per arm is a sensible default. Always complete the same number of reps on both sides to keep your back balanced.
Is this a good exercise for beginners?
Yes. The rack support stabilizes your torso and the single-arm setup is easy to learn, making it a beginner-friendly way to build back strength and fix left-to-right imbalances.
Where should I feel this exercise?
You should feel it mainly in the lat and middle of your back on the working side, with a stretch under the armpit at the bottom and a strong contraction near the shoulder blade at the top — not in your lower back or biceps.
