Description

This exercise involves lying on your back and moving your knees from side to side, which targets the core muscles.

How to Do Lying Side to Side Knee

  1. 1
    Setup

    Lie on your back with your knees bent, feet flat on the floor, and arms extended out to your sides at shoulder height with palms down.

  2. 2
    Setup

    Position your feet hip-width apart, ensuring your lower back maintains a gentle contact with the floor.

  3. 3

    Keeping your knees pressed together, slowly lower them to one side, allowing your hips to rotate naturally while keeping your shoulders grounded.

  4. 4

    Use your core muscles to gently pull your knees back up to the starting center position.

  5. 5

    Continue the movement by lowering your knees to the opposite side, maintaining control and a smooth motion throughout.

Tips

  • Keep your shoulders flat on the floor throughout the entire movement to ensure a proper spinal twist and maximize oblique engagement.
  • Focus on initiating the movement and returning to the center using your core muscles, rather than relying on momentum.
  • Maintain a steady, controlled pace; avoid letting gravity simply drop your knees to the side.
  • Breathe rhythmically, exhaling as your knees lower to the side and inhaling as you bring them back to the center.

Common Mistakes

  • ×Lifting your shoulders off the floor reduces the intended spinal rotation; focus on keeping both shoulder blades grounded to maximize the stretch and oblique activation.
  • ×Allowing your knees to separate during the movement diminishes core and adductor engagement; keep your knees pressed firmly together to maintain tension and stability.
  • ×Relying on momentum to swing your knees from side to side reduces muscle activation; slow down the movement and use controlled core strength to guide your knees.
