Single Leg Takedown: White Belt Biomechanics

1. Initiate from a neutral standing stance, feet shoulder-width apart.
2. Secure a collar grip with your left hand and a sleeve grip (right sleeve) with your right hand.
3. Step your right foot forward, slightly to the outside of your opponent's right foot.
4. Simultaneously, drop your hips by bending your knees, aiming to get your left knee close to the mat.
5. Drive your left shoulder into your opponent's torso, turning your hips perpendicular to their body.
6. Secure your right arm around your opponent's right thigh, gripping your own right wrist with your left hand.
7. Drive forward with your hips, extending your legs and pulling your opponent's leg towards your chest as you bring your opponent down.

• Lunging forward with your head up: This can lead to a slam or a dangerous head/neck injury by overextending your cervical spine.
• Incorrect knee placement: Dropping your knee directly to the mat without proper hip drive can hyperextend your knee joint if the opponent resists.
• Gripping too low on the leg: This provides less control and leverage, increasing the risk of losing the grip and compromising your base, leading to a fall.
• Trying to lift the leg instead of driving through: This places excessive strain on your lower back and shoulders, risking muscle strains.

1. Solo drill: Practice the footwork and hip drop motion without a partner. (20 reps)
2. Assisted drill: Partner stands passively. Focus on grip acquisition, step, hip drive, and securing the leg. (10 reps per side)
3. Light resistance drill: Partner offers minimal resistance to the takedown. Focus on driving through. (25% resistance, 10 reps per side)
4. Controlled resistance drill: Partner attempts to defend the entry with light pressure. Focus on maintaining base and driving. (50% resistance, 10 reps per side)
5. Dynamic resistance drill: Partner actively tries to sprawl or circle away. Focus on adjusting your drive and securing the leg. (75% resistance, 10 reps per side)
6. Live rolling: Attempt the single leg takedown in live rolling scenarios, prioritizing safety and technique over success. (90% resistance, 5 attempts)

• WHEN TO ATTEMPT:
• When your opponent is posturing up from your guard and you have an opportunity to create space.
• When facing an opponent who is actively pushing forward in the clinch, creating a forward momentum you can exploit.
• When your opponent is off-balance or has committed to a forward movement, leaving a leg exposed.
• PRIMARY COUNTERS:
• Sprawl: The opponent extends their hips and legs backward, placing their weight on your shoulders and preventing you from driving forward. You must then disengage or transition.
• Whizzer (overhook): The opponent secures an overhook on your arm on the side of the leg you are attacking, creating a strong frame to prevent your hip drive and often using it to circle out.
• Circle Out: The opponent uses their free limbs to create space and circle away from your attack, forcing you to release the grip or lose balance.
