Exercise guide

Seated Isometric Hold Pull Up

  • Intermediate
  • Compound
  • Timed hold
  • Back
  • Shoulders
  • Upper arms
  • Waist

This variation builds significant upper body pulling strength and isometric endurance by holding the peak contraction of a pull-up. It utilizes a bench for assisted entry, making it an excellent tool for mastering the top-end strength and scapular stability required for full pull-ups.

Muscles worked

Primary

  • Lats
  • Trapezius

Secondary

  • Abs
  • Obliques
  • Serratus anterior

Equipment

  • Pull up bar

Setup

  1. Place a flat bench directly under a pull-up bar, ideally within a power rack for stability.
  2. Sit on the bench and grasp the bar with an overhand grip, slightly wider than shoulder-width.
  3. Ensure your arms are fully extended and your torso is positioned directly under the bar.

How to do it

  1. Use your legs to help drive your body upward until your chin is positioned above the bar.
  2. Once at the top, lift your feet off the bench to transfer your full body weight to your upper body.
  3. Hold this peak contraction for the prescribed duration, maintaining a steady, controlled breathing pattern.
  4. Lower yourself back to the seated position on the bench with a slow, controlled eccentric motion.

Form checklist

  • Keep your shoulders depressed (pulled down away from your ears) throughout the hold.
  • Maintain a 'proud chest' by pulling your collarbones toward the bar.
  • Keep your core and glutes tight to prevent your body from swinging.
  • Ensure your chin stays above the bar without reaching or straining your neck.

Pro tips

  • Focus on driving your elbows down toward your back pockets to maximize lat and lower trap engagement.
  • Squeeze the bar as hard as possible; this 'irradiation' effect increases neural drive to the surrounding pulling muscles.
  • Imagine trying to pull the bar apart to further engage the rear deltoids and upper back.

Make it harder

  • Perform the isometric hold at the 'sticking point' where your elbows are at a 90-degree angle.
  • Add external resistance by wearing a weighted vest or holding a light dumbbell between your feet.
