Sit-up tutorial

The sit-up is a classic ab exercise in which the torso rises from lying on your back to a seated position. It strengthens the rectus abdominis and hip flexors and can be done at home without equipment; it suits beginners when performed with control.

How to perform

  1. Lie on your back with knees bent and feet flat on the floor.
  2. Cross your arms over your chest or place your fingertips beside your ears.
  3. Brace your core and tuck your chin slightly toward your chest.
  4. Contract your abs to peel your torso off the floor and rise to a seated position.
  5. Pause briefly at the top.
  6. Lower your torso slowly and under control back to the floor.
Breathing: Exhale as you sit up and inhale as you lower down.

Key tips

  • Roll the torso up one vertebra at a time rather than in one jerk.
  • If your feet lift, anchor them under something stable.
  • Make the lowering slower than the lifting.

Common mistakes

  • Pulling on the neck with the hands
  • Throwing the torso up with momentum
  • Dropping back to the floor abruptly
Safety: People with low back pain or disc problems should substitute a short-range crunch or plank.
