Description

A tuck crunch is a core exercise that targets the abs and obliques. It combines a traditional crunch with knee raises for an extra challenge.

How to Do Tuck Crunch

  1. 1
    Setup

    Lie on your back on a mat with your legs extended straight, hovering a few inches off the floor, and your hands lightly behind your head.

  2. 2
    Setup

    Lift your shoulder blades slightly off the mat, engaging your core, and ensure your lower back is pressed into the mat. This is your starting position.

  3. 3

    Exhale as you simultaneously pull your knees towards your chest and crunch your upper body, aiming to bring your elbows towards your knees.

  4. 4

    Inhale as you slowly extend your legs back to the starting position, keeping them slightly off the floor, and lower your upper body without fully resting your head.

  5. 5

    Maintain continuous tension in your abdominal muscles throughout the entire movement, avoiding letting your feet or head fully touch the ground.

Tips

  • Focus on initiating the movement from your core, actively pulling your navel towards your spine rather than just swinging your legs or head.
  • Control the eccentric phase by slowly extending your legs and lowering your upper body, maintaining constant tension in your abs.
  • Keep your lower back firmly pressed into the mat throughout the entire exercise to protect your spine and maximize abdominal engagement.
  • Avoid pulling on your neck with your hands; instead, use your hands to lightly support your head or keep them by your sides.

Common Mistakes

  • ×Many people pull their head forward with their hands, straining the neck; instead, keep your gaze fixed on the ceiling or use your hands only for light support behind your head.
  • ×Arching the lower back off the mat reduces abdominal engagement and can strain the spine; fix this by actively pressing your lower back down and reducing the range of motion if needed.
  • ×Swinging the legs or upper body to complete the crunch reduces core activation; instead, perform the movement slowly and controlled, focusing on muscle contraction.
