Ippon Seoi Nage BJJ Guide: Master This Essential Takedown for Jiu-Jitsu

Establish your grips: Secure a strong lapel grip with your non-throwing hand (e.g., left hand on opponent's right lapel) and a sleeve grip with your throwing hand (e.g., right hand on opponent's left sleeve).
Break balance (Kuzushi): Pull your opponent forward and slightly to the side to disrupt their posture and create an opening for your entry.
Step and turn: Step your lead foot (e.g., left foot) outside their lead foot, then quickly pivot on it, bringing your trailing foot (e.g., right foot) deep between their legs as you turn your back towards them.
Load the throw: As you turn, pull their sleeve arm tightly over your shoulder, tucking your elbow in. Bend your knees and drive your hips deep under your opponent's center of gravity.
Execute the throw: Maintain strong lapel and sleeve control, extend your legs, and lift with your hips, rotating your upper body to throw them over your shoulder.
Follow through: Release the lapel grip as they go over, maintaining the sleeve grip to control their fall and seamlessly transition into a dominant ground position like Side Control or mount.

Kuzushi is paraMount: Always break your opponent's balance before committing to the entry; a good pull makes the throw significantly easier.
Deep hip placement: Ensure your hips are deep and directly underneath your opponent's center of gravity for maximum leverage and power.
Tightness and posture: Keep your throwing arm tight to your body, creating a strong fulcrum. Maintain a strong, upright posture throughout the rotation to avoid bending at the waist.
Seamless transition: The throw is only half the technique; immediately follow through to the ground, maintaining control and securing a dominant position.

Drop Seoi Nage (Seoi Otoshi): A variation where you drop to one or both knees during the entry to get deeper under your opponent, especially effective against taller opponents.
Morote Seoi Nage: Similar body entry, but typically involves both hands gripping the opponent's sleeve or upper arm, often with a deeper 'back-carry' feel.
Kenka Yotsu Seoi Nage: Executed when you and your opponent have opposite lead feet, requiring a different footwork entry.

When your opponent is pushing into you, allowing you to capitalize on their forward momentum for Kuzushi.
From a standing grip fighting exchange where you can establish strong lapel and sleeve control.
As a counter to an opponent attempting a low Single Leg or double leg, by stepping in and going for the throw as they commit.

Sprawl: If you feel them entering, quickly sprawl your hips back and create distance, preventing them from getting their hips underneath you.
Hip toss/Ura Nage: If they commit and get under you, drive your hips into theirs and attempt to hip toss them over your shoulder, or circle to their back for an Ura Nage.
Step around: As they pivot and turn their back, step around their entry to their back, looking for a rear takedown or Back Take.
