Inside Trip

What This Is

The inside trip is a clinch takedown in which the practitioner hooks their near leg behind or around the opponent’s near leg from the inside — placing the trip leg between or inside the opponent’s legs — and uses the hook to trip the opponent’s leg outward, backward, or across, while simultaneously driving the upper body in the trip direction. The combined upper body drive and leg trip sweeps the opponent off their base.

The inside trip does not require a full leg lift or a traditional wrestling shot — the trip leg provides the base removal while the upper body drive provides the tipping force. The trip leg can hook behind the knee, behind the calf, or contact the inside of the ankle; the common element is that the tripping leg approaches from inside the opponent’s stance, not from the outside.

The inside trip is present in wrestling as a counter to single leg attempts, in judo as ko-uchi-gari and related techniques, and in Muay Thai as a sweeping trip from the clinch. In submission grappling, it is one of the most practical clinch takedowns because it requires no level change and can be applied directly from the standing clinch tie-up.

The Invariable in Action

The inside trip’s destabilisation comes from the simultaneous removal of one base leg and the application of force at the upper body. The leg trip removes the near foot’s support; the upper body drive pushes the centre of mass over the tripped leg. The opponent cannot maintain balance when the foot is swept away while the body is simultaneously pushed in the same direction — both supports fail at once.

The upper body drive in the inside trip moves the opponent’s centre of mass toward the tripped leg — the very leg that is being removed from the mat. Once the centre of mass is over the tripped leg and the leg is swept, the throw completes — the opponent has no remaining base in the direction of their displaced centre of mass.

Entering This Position

From Over-Under Clinch

The primary no-gi entry. From the over-under clinch, the practitioner with the underhook drives into the opponent’s chest while stepping the near leg between the opponent’s legs to hook the near leg from the inside. The underhook provides the upper body drive; the inside step establishes the trip leg. See: Over-Under Clinch.

From Front Body Lock

With both arms around the opponent’s waist in a front body lock, the practitioner steps one leg inside the opponent’s stance to trip the near leg as the body lock drives the upper body backward and to the side. See: Front Body Lock.

As a Counter to a Single Leg Attempt

When the opponent attempts a single leg takedown and has their head to the inside, the practitioner can apply an inside trip with the free leg — hooking behind the opponent’s near leg and driving them to the mat while the opponent’s shot is still in progress.

Trip Mechanics

The Trip Leg Position

The tripping leg steps to the inside of the opponent’s near leg — between the opponent’s feet. The calf or shin contacts the back or inside of the opponent’s near leg (behind the knee or ankle). From this position, the leg trips in the direction of the throw.

The Trip Direction

The inside trip can go to the side (sweeping the leg outward), backward (sweeping the leg back between the opponent’s own legs), or across (sweeping across the opponent’s stance). The direction is determined by the upper body drive direction — the leg trips in the same direction the body is being pushed.

Upper Body Drive

The trip does not work without simultaneous upper body pressure. The upper body drive (from the clinch grip) pushes the opponent’s torso in the trip direction while the leg removes the base. The two forces act together — upper body pushed toward the tripped leg, tripped leg removed from its support position.

From This Position

Side Control Top

When the inside trip sweeps the opponent to their side, the practitioner follows to side control top — maintaining the clinch grip as the opponent falls and landing in a top position beside the opponent’s torso.

Top Half Guard

If the opponent’s legs are caught between the practitioner’s during the trip, the landing may be top half guard. Maintain pressure and work to clear the half guard from the top position.

Turtle Top

An opponent who rolls away from the trip to prevent a back fall lands in turtle. The practitioner follows to turtle top.

Common Errors — and Why They Fail

Error: Tripping without upper body drive — leg sweeps while body stays neutral. Why it fails: A leg trip without the upper body drive gives the opponent space to step the tripped leg back and recover their balance. The upper body drive moves the centre of mass over the tripped leg — without this, the opponent simply lifts the tripped leg and replants it. Correction: Drive the upper body in the trip direction as the leg trips. One without the other is incomplete.

Error: Inside leg step too wide — leg ends up outside rather than inside the opponent’s stance. Why it fails: A trip leg that ends up outside the opponent’s near leg is an outside trip, not an inside trip. The trip direction and leverage are different. The inside trip requires the leg to enter between the opponent’s feet. Correction: Step the leg to the inside — between the opponent’s feet. If the leg is stepping to the outside of the near foot, adjust the angle.

Error: Trip applied when the opponent’s weight is fully on the near leg. Why it fails: A heavily loaded leg is difficult to trip — the opponent can simply plant the foot against the sweep force. The trip is most effective when the opponent is mid-step (weight transferring) or when the upper body drive has already shifted their weight away from the near leg. Correction: Drive the upper body first to shift the opponent’s weight, then trip the leg — or time the trip to the opponent’s weight transfer moment.

Drilling Notes

Step-in isolation. From over-under clinch, practise stepping the trip leg inside the opponent’s stance — without a trip. Confirm the leg position (between the feet, behind the knee). Count only successful inside positions, not outside contact.

Drive and trip simultaneously. Apply the upper body drive and the leg trip at the same moment. Partner takes a cooperative fall. Focus on the coordination of the two forces — they are not sequential.

Direction variation drill. Apply the inside trip in three directions: to the side, backward, and across. Each direction requires a slight upper body drive adjustment. This builds understanding of how the trip direction follows the upper body drive direction.
