Purpose

Practitioners who understand inside space control know that the structural key to leg entanglements is hip position, not grip. But training tends to reinforce the opposite habit: practitioners reach for the ankle or heel and then try to add hip position, which produces the grip-first sequence that connection precedes control identifies as a structural vulnerability. This drill forces the reversal by making hip-in-the-inside-space the sole scoring criterion.

The partner’s framing and stepping attempts create the realistic entry resistance that makes the hip-position task genuinely difficult. A practitioner who can seat their hip in the inside space against a stepping, framing partner has demonstrated the entry mechanic that makes leg entanglements structurally viable.

Setup

Both practitioners stand facing each other in neutral position. Attacker assumes a low posture appropriate for a leg entry attempt. Partner stands upright and is given the following instruction: attempt to prevent the attacker’s hip from reaching the inside space by stepping the threatened leg back, framing with the hands against the attacker’s shoulder or chest, or circling away. The partner may not sprawl or drop to the mat.

Scoring: The rep is successful when the attacker’s hip makes clear contact with the inside space — the attacker’s hip is pressing against the partner’s hip from inside, not outside. A heel grip without hip contact does not score.

Execution

Duration: 90 seconds of continuous entry attempts. After each successful hip-contact, both practitioners reset to standing neutral and the attacker attempts again.

Attacker’s task:

Initiate the ashi garami entry with the hip driving toward the inside space as the primary movement. The sequence is: lower level, drive the hip toward the partner’s hip pocket, establish hip contact before reaching for the heel. After the hip contact is made, the practitioner may grip the heel to complete the position — but the hip must arrive first.

The attacker should attempt multiple entries per 90-second block. Each entry begins from neutral and attempts to seat the hip before the partner can step or frame clear.

Partner’s task:

Use stepping, framing, and circling to prevent the attacker’s hip from entering the inside space. The partner may not grip the attacker’s clothing or body (no-gi rules apply), sprawl, or sit to the mat. The defence is purely positional — preventing the attacker’s hip from arriving in the inside space.

Report after each attempt: did the attacker’s hip reach the inside space, or only a heel grip?

Coaching Notes

The primary teaching point is the hip-drive initiation. Practitioners who begin the entry by reaching for the heel will find that the partner’s step back puts the heel out of reach before the hip can follow — they end up with an extended reach on a moving target. Practitioners who begin with the hip drive toward the inside space find that the partner’s step back must be larger to avoid the hip, and a larger step creates a longer period during which the inside space is available.

The 90-second duration produces multiple entry attempts, which is the correct training structure for an entry drill — the skill develops through volume of attempts, not through carefully analysed single reps.

Watch for practitioners who establish hip contact and then lose it while reaching for the heel. The hip should stay pressed into the inside space during the heel acquisition — the reaching hand should extend forward while the hip remains in contact. This is the same correction as in DRILL-INV07-01: connection maintained through the grip acquisition, not abandoned during it.

Common Errors

Heel reach before hip drive: The practitioner reaches for the ankle first and the hip follows after grip. The partner steps back, the grip travels with the step, and the hip never arrives in the inside space. Require the hip drive to begin before any reach.

Hip contact too shallow: The attacker’s hip touches the outside of the partner’s hip rather than entering the inside space. The attacker reports a successful rep but the structural contact is not in the inside space — only the hip surface is touching. Require the hip to be inside the space, not beside it.

Partner’s defence too passive: The partner stands and does not step or frame, making the entry trivially easy. Require active stepping — at minimum, the partner should take one step backward for every entry attempt. The drill only trains the correct hip-drive initiation when the defence is genuine.

Attacker abandons entry when partner steps: The attacker’s first entry attempt is blocked by a step-back, and the attacker resets without following the step. Train following the step rather than resetting — the inside space moves with the partner’s hip, and pursuing it is the correct response to a defensive step-back.
