How to Do Lying Elbow to Knee

  1. 1
    Setup

    Lie on your back on a mat with your knees bent, feet flat on the floor, and hands gently placed behind your head with elbows wide.

  2. 2
    Setup

    Engage your core to lift your head and shoulders slightly off the floor, bringing one knee up towards your chest so your shin is parallel to the floor.

  3. 3

    Exhale as you simultaneously rotate your torso, bringing the opposite elbow towards the raised knee, aiming to lightly touch them together.

  4. 4

    Inhale as you slowly extend the raised leg back towards the floor and return your torso to the starting position, maintaining tension in your core.

  5. 5

    Immediately repeat the movement on the other side, bringing the other knee to your chest and the opposite elbow towards it, alternating sides throughout the set.

Tips

  • Focus on controlled rotation from your obliques rather than just swinging your arm or leg with momentum.
  • Keep your lower back pressed firmly into the floor throughout the entire movement to maximize core engagement and protect your spine.
  • Maintain wide elbows and avoid pulling on your neck; your hands are there for support, not to yank your head up.
  • Fully extend the non-working leg towards the floor without touching it to increase the challenge and range of motion.

Common Mistakes

  • ×Using momentum instead of muscle engagement reduces effectiveness; slow down and focus on squeezing your obliques to perform each crunch.
  • ×Pulling on your neck strains your cervical spine; keep your elbows wide and initiate the movement from your abdominal muscles.
  • ×Lifting your lower back off the floor during the movement can cause discomfort; actively press your lumbar spine into the mat to maintain core stability.
