About this exercise

The chin-up isometric and negative variation focuses on two key phases to build pulling strength: a static hold at the top of the movement and a slow, controlled eccentric descent. This technique is especially effective for breaking through strength plateaus and building muscle under tension.

How to Perform

  • Grip the pull-up bar with an underhand (supinated) grip, hands shoulder-width apart
  • Pull yourself up until your chin clears the bar, fully engaging your lats and biceps
  • Hold the top position isometrically for 2–5 seconds, squeezing your back and arms
  • Begin a slow, controlled descent (negative), taking 3–5 seconds to lower yourself to full arm extension
  • Keep your core braced and avoid swinging throughout the movement
  • Pause briefly at the bottom, then initiate the next rep
