Supinated Grip Lat Pulldown

The supinated grip lat pulldown is a machine-based back exercise performed on a lat pulldown station with an underhand (palms-facing-you) grip on the bar. It targets the latissimus dorsi as the primary mover, similar to a standard pulldown, but the supinated grip recruits the biceps brachii more heavily and closely mirrors the pulling pattern of a chin-up. This makes it a useful option for building both back width and pulling strength for exercises like chin-ups.

Muscles Targeted

• Primary: Latissimus dorsi, biceps brachii
• Secondary: Rhomboids, lower trapezius, teres major
• Tertiary: Rear deltoids, forearm flexors (grip)

Starting Position

Sit at the lat pulldown machine with your thighs locked securely under the pads. Grasp the bar with a shoulder-width, underhand (supinated) grip, palms facing you. Lean back slightly, about 10-15 degrees, with your chest lifted, and let your arms extend fully overhead to stretch the lats before you begin pulling.

Execution Steps

1. Set up under the thigh pads with a shoulder-width supinated grip and arms fully extended overhead.
2. Initiate the pull by depressing and retracting your shoulder blades before bending your elbows.
3. Pull the bar down toward your upper chest, driving your elbows down and back close to your torso.
4. Squeeze your lats at the bottom, pausing briefly with the bar near your collarbone.
5. Control the return, extending your arms back to a full overhead stretch without letting the weight stack slam.
6. Repeat for the target reps, keeping your torso lean angle consistent throughout the set.

Form Cues

• Drive your elbows down and back rather than pulling with your hands.
• Keep the underhand grip at shoulder width - too narrow overloads the biceps, too wide limits pulling range.
• Use only a slight backward lean; avoid swinging the torso to generate momentum.
• Keep your chest lifted and shoulders down away from your ears throughout the pull.
• Fully extend your arms at the top of each rep to maintain a complete range of motion.

Common Mistakes

• Using torso swing or momentum to move the bar: reduces lat activation and increases lower-back strain; slow the tempo and pull with your back and arms only.
• Pulling the bar behind the neck: places excessive stress on the shoulder joint; always pull to the front, toward the upper chest.
• Letting the biceps take over the pull: since the supinated grip already recruits more biceps, initiate each rep from the shoulder blades to keep the lats primary.
• Not fully extending the arms at the top: shortens the range of motion and reduces the stretch on the lats.
• Gripping too wide: an overly wide underhand grip is uncomfortable on the wrists and negates the biceps-assisted advantage of this grip.

Variations

• Standard pronated (overhand) lat pulldown: shifts emphasis slightly more to the upper lats and less to the biceps.
• Close-grip V-bar pulldown: neutral grip on a V-handle, comfortable on the shoulders with a strong lat contraction.
• Single-arm supinated cable pulldown: unilateral version to address side-to-side strength imbalances.
• Assisted or banded chin-up: bodyweight alternative using the same supinated pulling pattern.

Tips for Progression

• Add weight in small increments once you can complete all sets with a full stretch and controlled tempo.
• Slow the eccentric to 3-4 seconds to increase time under tension.
• Work toward performing bodyweight chin-ups as your pulling strength improves.
• Increase reps to 12-15 before adding load if you notice grip or elbow strain.

Training Notes

Program the supinated grip lat pulldown 1-2 times per week as a primary back pull, typically for 8-12 reps across 3-4 sets, resting 60-90 seconds between sets. Pair it with a horizontal pulling movement, such as a row, for balanced back development.
