How to Do Seated Alternate Crunch

  1. 1
    Setup

    Sit on the floor with your knees bent, feet flat on the ground, and hands placed behind you for support, fingers pointing forward or slightly out.

  2. 2
    Setup

    Lean back slightly, engaging your core to maintain a stable and straight spine, ensuring your chest remains open and shoulders are relaxed.

  3. 3

    Exhale as you lift one knee towards your chest, contracting your abdominal muscles and hip flexors to bring your thigh closer to your torso.

  4. 4

    Inhale as you slowly and with control lower your foot back to the starting position, resisting gravity throughout the movement.

  5. 5

    Immediately alternate legs, smoothly transitioning to lift the other knee towards your chest, maintaining continuous core engagement.

Tips

  • Prioritize controlled movement over speed to maximize the engagement of your abdominal muscles and hip flexors, preventing reliance on momentum.
  • Keep your chest lifted and shoulders pressed down away from your ears to maintain proper posture and avoid unnecessary tension in your neck and upper back.
  • Focus on initiating the lift from your lower abs and hip flexors, imagining pulling your belly button towards your spine to enhance core stability.

Common Mistakes

  • ×Rounding the lower back excessively: Avoid collapsing into your lower back by actively engaging your core and keeping your chest lifted throughout the movement.
  • ×Using momentum to lift the legs: Ensure each leg lift is performed with deliberate control, slowly raising and lowering the leg rather than swinging it up.
  • ×Holding your breath: Coordinate your breath by exhaling as you lift your knee and inhaling as you lower it to support core activation and maintain oxygen flow.
