Exercise guide

Wide Chin Up

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Shoulders
  • Upper arms

The Wide Chin Up is a challenging compound movement that emphasizes the lower lats and biceps while building upper back thickness. By using a wider-than-shoulder underhand grip, you increase the stretch on the lats and place a unique mechanical demand on the biceps compared to a standard chin-up.

Muscles worked

Primary

  • Biceps
  • Lats
  • Trapezius

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Pull up bar

Setup

  1. Stand under the pull-up bar and grasp it with an underhand (supinated) grip, palms facing toward you.
  2. Position your hands approximately 4-6 inches wider than shoulder-width on each side.
  3. Hang with arms fully extended, cross your ankles, and engage your core to stabilize your lower body.

How to do it

  1. Exhale as you pull your body upward by driving your elbows down and back toward your hips.
  2. Continue the pull until your chin clears the bar, keeping your chest lifted and shoulders retracted.
  3. Inhale as you lower yourself back to the starting position using a controlled 3-second eccentric tempo.
  4. Maintain a slight arch in the upper back throughout the entire range of motion.

Form checklist

  • Avoid 'shrugging' by keeping your shoulders depressed away from your ears.
  • Eliminate momentum or leg swinging; the movement should be strictly from the upper body.
  • Ensure full elbow extension at the bottom of every rep without losing tension in the lats.
  • Keep your elbows tucked slightly forward rather than allowing them to flare excessively wide.

Pro tips

  • Focus on the 'mind-muscle connection' by imagining you are pulling the bar down to your chest rather than pulling your body up.
  • Squeeze your shoulder blades together at the peak of the movement to maximize trapezius and rhomboid activation.

Make it harder

  • Attach a weight belt with plates to increase the resistance once you can complete 10-12 bodyweight reps with perfect form.
  • Implement a 5-second slow eccentric (lowering phase) to increase time under tension and muscle fiber recruitment.
