How to do the Criss-Cross Knee-Tuck

  1. Start by sitting on the floor with your legs extended in front of you and your arms resting by your sides for balance.

  2. Leaning back slightly, engage your core and lift your legs a few inches off the ground to get into the starting position. This will be your base throughout the exercise.

  3. While keeping your core tight and back straight, bend your right knee and bring it towards your chest.

  4. Simultaneously, twist your torso to the left, aiming to touch your right knee with your left elbow.

  5. Return to the starting position with your legs extended and torso centered.

  6. Repeat the movement on the opposite side, this time bending your left knee towards your chest and twisting your torso to bring your right elbow towards your left knee.

  7. Alternate sides for each repetition, ensuring you complete a full twist and knee tuck on each side.

  8. Perform the exercise for the desired number of repetitions and sets, maintaining proper form and controlled movements throughout.

Remember to breathe steadily throughout the exercise, exhaling as you twist and tuck your knee, and inhaling as you return to the starting position.
