For information, we make a crunch to get up every morning, the crunch becomes negative like all other movements if it is done in excess.

This is the instructions for the crunch on the floor

  • 1. Lie down completely on the floor and place your hands behind your head without pulling on your neck.
  • 2. Bend the knee 90 degrees above your hips. Then put your feet on the ground about 20 cm from the pelvis.
  • 3. While exhaling, bring your chin as close to your knees as possible. Keep a neutral look and your eyes follow the movement.
  • 4. Then release and return to the initial position.
  • 5. Continue your series by repeating the movement.
