Exercise guide

Corn Cob Side To Side Pull Up

  • Advanced
  • Compound
  • Rep-based
  • Back
  • Shoulders
  • Upper arms
  • Waist

This advanced pull-up variation builds exceptional upper body strength and lateral stability by shifting body weight from side to side at the peak of the contraction. It significantly increases time-under-tension for the lats, biceps, and rear deltoids while demanding high levels of scapular control.

Muscles worked

Primary

  • Lats
  • Trapezius

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Grip the bar with an overhand (pronated) grip, slightly wider than shoulder-width.
  2. Hang with arms fully extended and feet off the floor, engaging your core to prevent swinging.
  3. Depress your scapula by pulling your shoulders down and away from your ears to engage the lats.

How to do it

  1. Exhale as you pull your chest toward the bar until your chin is clearly above the bar level.
  2. Maintain the top height and shift your body weight horizontally until your chin is positioned over your right hand.
  3. Shift horizontally across the bar until your chin is positioned over your left hand.
  4. Return to the center and inhale as you lower yourself back to a full dead-hang with a controlled 2-3 second tempo.

Form checklist

  • Keep your chin above the bar throughout the entire lateral shift phase.
  • Maintain a rigid core and keep your legs still to prevent swinging or using momentum.
  • Ensure your shoulders stay pulled down; do not let them shrug toward your ears during the shift.
  • Move in a straight horizontal line rather than dipping your chest down in the middle of the shift.

Pro tips

  • Think about pulling the bar 'down' with the side you are moving toward while using the opposite arm to stabilize and push slightly.
  • Squeeze your shoulder blades together throughout the shift to maximize trapezius and rhomboid activation and maintain height.

Make it harder

  • Perform multiple lateral shifts (e.g., right-left-right-left) before descending to the starting position.
  • Wear a weighted vest to increase the demand on the isometric hold and lateral transition.
