Sit up with Chair Assisted

The Sit Up with Chair Assisted is a modified exercise that helps you strengthen your core while providing support.

  1. Begin by sitting on the edge of a sturdy chair with your feet flat on the ground.
  2. Lean back slightly, engaging your core muscles.
  3. Slowly lift your upper body towards your knees, keeping your back straight.
  4. Lower yourself back down to the starting position and repeat.

How to perform the Sit up with Chair Assisted

  1. Set up. Set up in a stable, balanced starting position appropriate for the Sit up with Chair Assisted using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
