Seated Two Arm Palms Up Low Pulley Wrist Curl

The seated two arm palms up low pulley wrist curl is a forearm isolation exercise that trains the wrist flexors using a straight bar attached to a low cable pulley instead of a barbell. Sitting close to the machine with forearms resting on the thighs keeps the elbows and upper arms completely still, so the movement isolates wrist flexion and extension. The cable adds continuous tension through the full range, including the stretched bottom position that free weights tend to unload.

Muscles Targeted

• Primary: Wrist flexors (flexor carpi radialis, flexor carpi ulnaris)
• Secondary: Flexor digitorum superficialis
• Tertiary: Brachioradialis (isometric stabilization)

Starting Position

Sit on a bench positioned close to a low cable pulley fitted with a straight bar attachment. Lean forward and grasp the bar with both hands, palms facing upward, using a shoulder-width grip. Rest your forearms on your thighs with your wrists hanging just past your knees, letting the bar roll down toward your fingertips so your wrists start in a fully extended position.

Execution Steps

1. Rest your forearms firmly on your thighs so only your wrists and hands move
2. Let the bar roll down toward your fingertips at the bottom of each rep for a full stretch
3. Curl the bar upward by flexing your wrists as high as possible
4. Squeeze at the top of the movement, holding briefly before descending
5. Lower the bar under control back to the fully extended starting position
6. Keep your forearms stationary throughout, avoiding any lift from the thighs
7. Repeat for the target number of reps without swinging the weight

Form Cues

• Anchor the forearms: Press them into your thighs the entire set so the elbows and upper arms never move
• Use a full range of motion: Let the bar roll to the fingertips at the bottom and curl fully at the top
• Keep the grip loose at the bottom: Allowing the bar to roll into the fingers increases the stretch on the flexors
• Move slowly and deliberately; this is a small muscle group that responds poorly to momentum
• Keep your torso still and lean slightly forward to maintain a stable base

Common Mistakes

• Lifting the forearms off the thighs: This recruits the biceps and shoulders and reduces isolation of the forearm flexors. Keep constant contact between forearms and legs.
• Using too much weight: Excess load limits range of motion and causes the wrists to jerk rather than curl smoothly. Use light to moderate weight and prioritize full range.
• Rushing the tempo: Fast reps rely on momentum and reduce muscle tension. Slow down both the lifting and lowering phases.
• Restricting the bottom stretch: Gripping too tightly at the bottom prevents the bar from rolling into the fingers, cutting the range short. Allow the fingers to open slightly at the bottom.
• Poor posture: Slouching or leaning too far back changes the cable angle and reduces tension on the forearms. Sit upright with a slight forward lean.

Variations

• Barbell wrist curl: Free-weight version performed on a bench, without constant cable tension
• Seated palms-down low pulley wrist curl: Reverse grip that targets the wrist extensors instead of flexors
• Dumbbell wrist curl: Single-arm version allowing independent range of motion for each side
• Behind-the-back barbell wrist curl: Standing variation performed with the bar behind the glutes
• Cable wrist curl with rope attachment: Rope allows a slightly different hand path and grip challenge

Tips for Progression

• Increase the pin-selected weight in small increments once full range of motion feels controlled
• Add a 1-2 second hold at the top of each rep before progressing weight
• Increase reps toward the 15-20 range before adding load, since forearms tolerate higher volume
• Slow the eccentric phase to increase time under tension without changing the weight

Training Notes

Train the seated two arm palms up low pulley wrist curl 2-3 times per week as a finishing exercise after compound pulling or pressing work, since fatigued forearms can limit grip on heavier lifts if trained first. Use 2-3 sets of 12-20 reps with light to moderate weight, resting 45-60 seconds between sets. Consistent forearm training here supports grip strength that carries over to deadlifts, rows, and pull-ups.
