Weighted Chin-Up

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

The weighted chin-up is an advanced compound pulling exercise that builds exceptional upper body strength and mass, specifically targeting the lats and biceps. By adding external load, it forces the core and rotator cuff to stabilize the torso while the primary movers work against increased resistance.

Equipment

  • Pull up bar

Setup

  1. Secure a weight plate to a dip belt around your waist or firmly grip a dumbbell between your ankles.
  2. Stand under the bar and use an underhand (supinated) grip with hands shoulder-width apart.
  3. Step off the wall or platform to hang with arms fully extended, ensuring the weight is stable and not swinging.
  4. Engage your core and depress your shoulder blades by pulling them down away from your ears.

How to do it

  1. Exhale as you pull your body upward by driving your elbows down toward your hips and keeping your chest lifted.
  2. Continue the ascent until your chin is completely over the bar, focusing on a peak contraction in the biceps and lats.
  3. Inhale as you lower yourself back to the starting position with a controlled 2-3 second eccentric phase.
  4. Stop just short of a 'dead hang' to maintain tension in the lats and protect the shoulder joints before starting the next rep.

Form checklist

  • Keep your elbows tucked close to your sides rather than flaring them out.
  • Avoid 'kipping' or using leg momentum to swing yourself over the bar.
  • Ensure a full range of motion by clearing the bar with your chin and fully extending the arms at the bottom.
  • Maintain a 'proud chest' throughout the movement to maximize lat recruitment and prevent rounded shoulders.
  • Keep your core braced to prevent excessive arching in the lower back.

Pro tips

  • Imagine pulling the bar down to your chest rather than pulling your body to the bar to improve mind-muscle connection with the lats.
  • At the top of the rep, squeeze your shoulder blades together to increase activation of the trapezius and rhomboids.

Make it harder

  • Incorporate a 3-second pause at the top of each rep to eliminate all momentum and maximize time under tension.
  • Perform '1.5 reps' by pulling to the top, lowering halfway, pulling back to the top, and then lowering fully.
