1. Stance (Muay Thai Guard/Ready Position)

• Foot Position:
  Begin in your Muay Thai stance, with your right foot forward (for an orthodox stance). Keep your feet about shoulder-width apart, and distribute your weight evenly across the balls of your feet, ready to move.
• Knees and Hips:
  Keep your knees slightly bent to maintain balance and mobility. Hips should be relaxed, ensuring fluid movement when you spring off the ground for the jump.
• Hands/Guard:
  • Lead hand (right) should be up near your face, ready to guard or disrupt your opponent’s defense.
  • Rear hand (left) should be near the chin, ensuring protection against any incoming attacks.
  • Keep your elbows tucked in to protect the ribs and maintain overall defense.

2. Preparation (Chambering the Jump Fly Knee)

• Shift Weight:
  Transfer most of your weight onto your right leg (the back leg). This is essential for generating upward and forward momentum.
• Chamber the Rear Knee (Left):
  Lift your left knee up towards your chest, ensuring the knee is bent at about 90 degrees. Engage your core and maintain balance, preparing for the explosive jump.
• Engage Core and Hips:
  Before jumping, tighten your core, and prepare to thrust your hips forward as you drive the knee.

3. Executing the Jump Fly Knee (The Strike)

1. Step 1 – Jump Up:
   Push off with your right leg to propel yourself upwards. As you spring into the air, make sure to keep your core tight to stabilize your body.
2. Step 2 – Extend the Left Knee:
   As you reach the peak of your jump, thrust your left knee upward and forward. Aim for the target area—typically the opponent’s midsection, chest, or head, depending on the distance and positioning.
3. Step 3 – Hips and Torso Engagement:
   Drive your hips forward and slightly rotate your torso toward your opponent. This will help to add more power and precision to the knee strike, making it more damaging.
4. Step 4 – Maintain Balance:
   While executing the strike, keep your upper body slightly tilted back to avoid falling forward after the knee lands. Ensure your balance is maintained even while airborne.

4. Footwork and Recovery

1. Quick Leg Retract:
   Once the knee lands (or misses), quickly bring your left leg back to a neutral position under you to prepare for defense or another attack.
2. Return to Guard:
   After landing, immediately bring both hands back to your guard position to protect against potential counters.
3. Reset Stance:
   Depending on the distance covered during the jump, reset your position by adjusting your foot placement to get back into a balanced stance, ready for follow-up strikes or defensive moves.

5. Defensive Positioning and Protection

1. Rear Hand Guard:
   As you jump and strike, always keep your rear hand (left) up to guard against counters, especially hooks, uppercuts, or elbows from your opponent.
2. Lead Hand Awareness:
   Your lead hand (right) should be ready to block or check any incoming strikes while the knee is in motion. It can also help to disrupt the opponent’s guard and create openings.
3. Head Positioning:
   Maintain a slight lean back during the jump to make yourself a harder target while executing the knee. Avoid completely leaning back, as it might compromise your balance or landing.

6. Follow-Up and Recovery

1. Immediate Return to Guard:
   After completing the strike and landing safely, quickly bring both hands back to a defensive position. This ensures you’re protected from counters and ready to act.
2. Follow-Up Strikes:
   The jump fly knee is often used in combinations. After landing, you might follow up with:
   • A cross or jab to keep the pressure on the opponent.
   • A low kick to exploit any openings.
   • A clinch for control, especially if your opponent is off-balance from the knee.
3. Reposition:
   If you’ve moved significantly during the jump, adjust your footwork to maintain distance, positioning, and balance for the next phase of the fight.

7. Common Mistakes to Avoid

1. Overextending the Jump:
   Avoid jumping too far or too high, as this may leave you off-balance or open for counters. The jump should be explosive yet controlled.
2. Dropping Hands:
   Never drop your hands during the jump. Always keep your rear hand (left) up to protect your face, as you are vulnerable during the air phase.
3. Lack of Core Engagement:
   Failing to engage your core can weaken the strike and make the jump less controlled. Always maintain tight core muscles to improve both the knee’s power and balance.
4. Not Retracting Quickly:
   After the knee strike, make sure to quickly pull your leg back and reset your stance. Failure to do so leaves you vulnerable to counters and attacks.

8. Advanced Concepts

1. Feinting the Jump Fly Knee:
   At an advanced level, you can feint the jump knee to bait your opponent into reacting, creating an opening for follow-up strikes like an uppercut, hook, or low kick.
2. Timing the Jump:
   The jump fly knee works best when timed to catch your opponent off guard. Wait for moments when your opponent is retreating or adjusting their guard, and then explode with the knee.
3. Using the Jump Fly Knee in the Clinch:
   If your opponent is in a clinch, a quick jump fly knee can create distance, disrupt their balance, and give you an advantage to follow up with additional attacks.
4. Knee to Head:
   For advanced practitioners, the jump fly knee can be aimed at the opponent’s head when they are positioned lower, or when they’re on the defensive. This is particularly effective when closing the distance quickly.
