How to Do Knee Touch Crunch

  1. 1
    Setup

    Lie on your back with your knees bent at a 90-degree angle and your feet flat on the floor, hip-width apart. Place your hands lightly behind your head, keeping your elbows wide.

  2. 2
    Setup

    Ensure your lower back is pressed into the floor, maintaining a neutral spine without arching your back.

  3. 3

    Exhale as you engage your core, lifting your head, neck, and shoulders off the floor, curling your torso upwards. Focus on bringing your elbows towards your knees.

  4. 4

    Continue to crunch until your elbows lightly touch or come very close to your knees, feeling a strong contraction in your rectus abdominis.

  5. 5

    Inhale slowly as you control the movement, lowering your upper body back to the starting position without fully resting your head or shoulders on the floor before the next repetition.

Tips

  • Focus on initiating the movement from your abdominal muscles, not by pulling on your neck or using momentum from your arms.
  • Maintain a slight gap between your chin and chest throughout the crunch to avoid straining your neck; imagine holding an orange under your chin.
  • Control the eccentric (lowering) phase of the movement for at least two seconds to maximize muscle engagement and time under tension.
  • Keep your lower back firmly pressed into the floor during the entire exercise to protect your spine and ensure proper abdominal engagement.

Common Mistakes

  • ×Pulling on your neck: Avoid yanking your head forward with your hands; instead, keep your hands light on your head and let your core muscles do the work.
  • ×Lifting too high or using momentum: Prevent lifting your entire back off the floor or swinging your body; focus on a controlled, partial curl that targets the rectus abdominis.
  • ×Not controlling the descent: Ensure you slowly lower your torso back down, resisting gravity, rather than letting your body drop quickly to the starting position.
