How to do the Chair Seated Knee Thrust

  1. Starting Position:

    • Sit on the edge of a sturdy chair with your feet flat on the floor.

    • Keep your back straight and engage your core for support.

    • Position your arms at your sides or place your hands on the chair for additional stability.

  2. Movement:

    • Lift your right arm straight up above your head while keeping your left hand resting on the chair or at your side for balance.

    • Simultaneously, lift your right knee towards your chest, bringing it up as high as you can.

    • Your torso should remain upright as you perform this motion.

  3. Return to Starting Position:

    • Lower your right arm and your right knee back to the starting position in a controlled manner.

  4. Repetitions:

    • Repeat the movement for a set number of repetitions (e.g., 10-15 reps) before switching to the left side.

    • Perform the same number of repetitions with your left arm and left knee.

  5. Tips:

    • Keep your movements smooth and controlled to avoid straining your muscles.

    • Focus on using your core muscles to stabilize your body as you lift your legs.

    • Breathe out while lifting your arm and knee, and breathe in as you lower them back down.

  6. Modification:

    • If you're new to this exercise, you can start by lifting just your knee without using your arm and gradually add the arm movement as you become more comfortable.
