Close Grip Chin-Up

The close grip chin-up is a bodyweight vertical pulling exercise performed on a fixed bar using an underhand (supinated) grip narrower than shoulder width. The narrow, palms-facing grip increases biceps involvement compared to a standard shoulder-width chin-up while still heavily recruiting the latissimus dorsi and other back muscles. It's a compound, multi-joint movement that builds pulling strength and upper-body mass. Because it uses bodyweight as resistance, it scales easily with assistance bands or added weight.

Muscles Targeted

• Primary: Latissimus dorsi, biceps brachii
• Secondary: Rhomboids, trapezius, posterior deltoids
• Tertiary: Forearms, core

Starting Position

Grasp a fixed pull-up bar with an underhand grip, hands about 6-10 inches apart, closer than shoulder width. Hang with your arms fully extended, shoulder blades engaged out of a loose dead hang, and feet off the floor, keeping your body in a straight line from shoulders to heels.

Execution Steps

1. Initiate the pull by depressing your shoulder blades down and back before bending the elbows
2. Pull your body upward by driving your elbows down toward your hips
3. Keep your elbows close to your torso as you rise, rather than flaring them outward
4. Continue pulling until your chin clears the bar
5. Pause briefly at the top with your back and biceps fully contracted
6. Lower yourself with control back to a full arm extension
7. Repeat for the desired number of reps without swinging or kipping

Form Cues

• Start from a dead hang: Full arm extension at the bottom ensures a complete range of motion
• Lead with the elbows: Think about driving elbows down and back rather than just curling the bar toward you
• Keep the core braced: A tight core prevents excessive swinging or leg kicking during the pull
• Control the descent: Lower yourself over 2-3 seconds rather than dropping quickly
• Keep the grip stable: Find a hand spacing narrow enough to emphasize the biceps but wide enough to avoid wrist strain

Common Mistakes

• Using momentum: Swinging or kipping the body reduces muscle tension and increases shoulder strain; keep the movement strict.
• Not reaching full extension: Stopping short at the bottom shortens the range of motion and reduces lat and bicep engagement.
• Flaring the elbows out: This shifts emphasis away from the back and biceps and toward the shoulders.
• Craning the neck to clear the bar: Straining the neck forward instead of pulling with the back can cause neck strain; drive with the elbows instead.
• Rushing the eccentric: Dropping quickly from the top skips the negative portion, which builds significant strength.

Variations

• Wide-grip pull-up: A grip variation that shifts more emphasis to the outer lats and less to the biceps
• Assisted chin-up: Using a resistance band or assisted pull-up machine reduces bodyweight load for beginners
• Weighted close grip chin-up: Adding a weight belt or vest increases resistance for advanced trainees
• Negative close grip chin-up: Focusing only on the slow lowering phase builds strength toward a full rep
• Neutral-grip chin-up: Using parallel handles reduces wrist strain while maintaining a similar muscle emphasis

Tips for Progression

• Master the negative: Practice slow 3-5 second lowering phases if you can't yet complete a full rep
• Use band assistance: Gradually reduce band thickness as you build strength toward unassisted reps
• Increase reps: Build toward 3 sets of 8-10 clean reps before adding external weight
• Add weight gradually: Once bodyweight reps are easy, add small increments via a dip belt or weighted vest

Training Notes

Train close grip chin-ups 2-3 times per week as part of a back or pulling-focused session, using 3-4 sets of 6-10 reps with 60-90 seconds of rest between sets. They work well as a primary pulling movement early in a workout, before accessory back and bicep isolation exercises.
