About this exercise

A classic abdominal exercise performed with the feet anchored under a chair for stability, allowing a full range of motion sit-up. The foot anchor reduces hip-flexor dominance and keeps focus on the abdominals throughout the movement.

How to Perform

  • Lie on your back on the floor and slide your feet under the front legs of a sturdy chair to anchor them
  • Bend your knees at approximately 90 degrees, feet flat on the floor
  • Place your hands behind your head or cross them over your chest
  • Exhale and curl your torso up, bringing your chest toward your knees
  • Pause at the top of the movement, then slowly lower yourself back to the floor
  • Keep the movement controlled — avoid pulling on your neck with your hands
  • Repeat for the desired number of repetitions
