About this exercise

The Inverted Chin Curl with Bent Knee between Chairs is a bodyweight biceps-focused pulling exercise using two chairs as improvised equipment. The supinated (underhand) grip shifts the primary emphasis to the biceps, while the bent-knee setup reduces the load to make the movement accessible for beginners.

How to Perform

  • Set up two sturdy chairs with a support bar or broomstick across the seats at a manageable height
  • Lie on your back beneath the chairs with knees bent and feet flat on the floor
  • Grip the support with a supinated (underhand, palms facing you) grip at about shoulder-width
  • Keep your body aligned from knees to shoulders and engage your core
  • Curl your chest up toward the bar by bending your elbows, focusing on squeezing the biceps
  • Pause briefly at the top when your chest is close to the bar
  • Lower yourself back to the start position slowly and with control
