The Art of the Stabbing Knee (Khao Trong)
Mastering the Stabbing Knee
The stabbing knee, or Khao Trong, is one of the most powerful and direct weapons in Muay Thai. Unlike curving knees that score on the outside, the stabbing knee travels in a straight line, driving forward with the full force of your hips to penetrate your opponent's guard. It's a devastating tool both at range and up close, capable of stopping an opponent's forward pressure and creating fight-ending damage. Mastering the mechanics of this fundamental strike is essential for any Nak Muay.
Fundamental Knee Drills
Drill 1: The Basic Stabbing Knee
Focusing on pure mechanics.
1. The Grip: Place both hands on your partner's shoulders or the top of the heavy bag.
2. The Step: Take a small step forward with your lead foot to get in range.
3. The Drive: Drive your hips forward explosively as you bring your rear knee straight up and into the target.
4. Reset: Place your foot back down and reset your stance.
Drill 2: The Intercepting Knee
Using the knee as a defensive stop-hit.
1. The Feed: Have your partner take a single, deliberate step forward as if entering to punch.
2. The Timing: As soon as you see their weight shift forward, you must react.
3. The Knee (Options):
- Lead Knee: For a quick interception, throw a sharp Lead Stabbing Knee.
- Rear Knee: For more power, slightly angle your lead foot out as they step in and drive a powerful Rear Stabbing Knee.
Drill 3: The Double Knee
For rhythm and balance.
1. The First Knee: Throw a Rear Stabbing Knee.
2. The Reset: As you place your rear foot down, immediately shift your weight.
3. The Second Knee: Without pausing, throw a Lead Stabbing Knee. This teaches you to chain your knees together.
Drill 4: 1-4 Stabbing Knees
Integrating knees into boxing combos.
1 Knee: Jab -> Rear Knee.
2 Knee: Jab, Cross -> Switch Knee.
3 Knee: Jab, Cross, Lead Hook -> Rear Knee.
4 Knee: Jab, Cross, Lead Hook, Cross -> Switch Knee.
Keys to a Powerful Stabbing Knee
- Thrust Your Hips: The power does not come from lifting your leg; it comes from an explosive forward thrust of your hips.
- Point Your Toes: Keep your foot extended and toes pointed down towards the floor. This sharpens the knee and helps it penetrate the target.
- Pull as You Push: Use your hands to pull your opponent's shoulders or head down as you drive your knee up. This push-pull motion dramatically increases power.
- Stay on the Ball of Your Foot: Your supporting foot should be slightly raised on the ball, allowing for better balance and hip rotation.
Round Knees
Fundamental Muay Thai Knees
The Art of the Round Knee (Khao Khong)
Mastering the Round Knee
While the stabbing knee is for direct, forward pressure, the round knee (Khao Khong) is a devastating weapon for attacking from the side. It travels in a horizontal arc, similar to a roundhouse kick, targeting the ribs, liver, and spleen. The power comes from opening the hip and pivoting the body, making it a perfect tool to use in the clinch or as a counter when an opponent exposes their side.
Fundamental Round Knee Drills
Drill 1: Basic Round Knee Mechanics
Focusing on the core movement.
1. The Grip: Secure a 50/50 clinch on your partner or the heavy bag.
2. Open the Hip: Take a small step out to the side with your supporting foot to open your hip.
3. The Arc: Swing your knee in a horizontal arc, aiming to land with the inside of your knee on the target.
4. Reset: Bring your leg back and reset your stance.
Drill 2: Hook to Same-Side Knee
A natural, flowing combination.
1. The Hook: Throw a hard Lead Hook to get your partner to raise their guard.
2. The Flow: Use the hip rotation from the hook to immediately flow into a Lead Round Knee to the now-exposed body.
Drill 3: Off-Balance to Knee
Using the clinch for control.
1. The Clinch: Establish inside control in a 50/50 clinch.
2. The Pull: Forcefully pull your partner's head and shoulder down and to one side.
3. The Knee: As they are off-balanced, deliver a powerful Round Knee to their exposed ribs.
Drill 4: 1-4 Round Knees
Integrating round knees into boxing combos.
1 Knee: Jab -> Rear Round Knee.
2 Knee: Jab, Cross -> Switch Round Knee.
3 Knee: Jab, Cross, Lead Hook -> Rear Round Knee.
4 Knee: Jab, Cross, Lead Hook, Cross -> Switch Round Knee.
Keys to a Powerful Round Knee
- Open Your Hips: The power comes from turning your hips over. Take a small step to the side with your standing foot before you throw.
- Turn Your Supporting Foot: Pivot on the ball of your supporting foot as you throw the knee to maximize hip rotation and power.
- Strike with the Inside: Unlike the stabbing knee, you want to land with the hard, bony inside part of your knee and upper shin.
- Use Your Arms to Pull: In the clinch, pull your opponent into the knee to amplify the impact significantly.
Knee Combinations
Fundamental Knee Combinations
Mixing Hands, Kicks, & Knees
Attacking Multiple Lines
Once you understand the basic stabbing and round knee, the next step is to combine them with your other weapons. Punches and kicks are used to close the distance, create openings, and set up your devastating knee strikes. By mixing these attacks, you force your opponent to defend multiple levels and angles at once, creating openings and overwhelming their defense.
Basic Knee Combination Drills
Drill 1: Punch to Stab & Round
Using punches to enter knee range.
1. The Setup: Throw a Jab-Cross to bring your opponent's guard up.
2. The Stab: Step in behind your cross and throw a hard Rear Stabbing Knee up the middle.
3. The Round: As you set your rear foot down, immediately throw a Lead Round Knee into their exposed ribs.
Drill 2: Hook to Clinch & Turn
Using a hook to enter the clinch.
1. The Entry: Throw a Lead Hook and enter a 50/50 clinch as you throw it.
2. The Round: Immediately land a Lead Round Knee to their side.
3. The Turn & Stab: Use the impact and your clinch grip to turn your opponent slightly, then drive a powerful Rear Stabbing Knee straight into their midsection.
Drill 3: Kick to Knee
Using a kick to set up a level change.
1. The Kick: Land a hard Rear Low Kick to your partner's lead thigh. This will draw their attention and weight downwards.
2. The Stab: As they react to the low kick, step forward and drive a Rear Stabbing Knee straight up the middle to their body.
Keys to Effective Knee Combinations
- Fluid Hips are Key: The ability to switch between a forward hip thrust (stab) and a rotational hip turn (round) is crucial. Practice the movements slowly.
- Close Distance Safely: Always enter knee range behind your strikes. A naked step-in is an invitation for your opponent to counter.
- Don't Reset Fully: To be fast, you must flow from one strike into the next. Avoid planting your foot flat and resetting your stance completely between strikes.
- Sell the Setup: Your initial punches or kicks need to be thrown with intent. A weak setup won't create the opening needed for the knee.
Knee Combinations
Knee Defense: The Parry
Redirecting Power and Creating Angles
Turning Defense into Offense
Instead of simply blocking a knee, the parry is an active defense designed to redirect your opponent's momentum. By pushing their incoming knee across your body, you not only avoid damage but also force them off-balance, turning their hips and exposing their side for an immediate and powerful counter-attack. It's a high-level technique that turns a dangerous situation into a dominant offensive opportunity.
Knee Parry Drills
Drill 1: The Basic Parry
Focusing on the core mechanic.
1. The Attack: Your partner throws a slow, controlled rear stabbing knee.
2. The Parry: Use your lead hand to make contact with the outside of their incoming thigh.
3. The Push: Give a firm, sharp push to guide their leg across your body. Focus on feeling their momentum shift. Reset and repeat.
Drill 2: Parry to Punch
The most common follow-up.
1. The Attack: Partner throws a rear knee.
2. The Parry: Parry the knee with your lead hand.
3. The Counter: As their side becomes exposed from the parry, immediately throw a powerful Rear Cross or a Cross-Hook combination.
Drill 3: Parry to Low Kick
Attacking the base.
1. The Attack: Partner throws a rear knee.
2. The Parry: Parry the knee hard with your lead hand.
3. The Counter: As you push their leg across, their supporting leg will be momentarily loaded with all their weight. Immediately fire a hard Rear Low Kick into their supporting thigh or calf.
Drill 4: Parry to Clinch Entry
Turning defense into a dominant position.
1. The Attack: Partner throws a rear knee.
2. The Parry: Parry the knee with your lead hand.
3. The Entry: As you push their leg by, step in with your rear foot to close the distance. Use your rear hand to secure a collar tie.
4. The Counter: Immediately throw a powerful Rear Knee to the body.
Keys to an Effective Knee Parry
- Use the Opposite Hand: To effectively turn their hips, parry a rear knee with your lead hand, and a lead knee with your rear hand.
- Push, Don't Slap: Make firm contact on their thigh and push through. A light slap will not redirect a committed knee strike.
- Commit to the Angle: The parry creates a dominant angle for you. Immediately step into that new angle as you counter to maximize your advantage.
- Counter Instantly: The window of opportunity when they are off-balance is very small. Your counter must be thrown at the same time as the parry.
