Kit: Mats. Gi or no-gi both work — grips are described for both.
Mat Movements
Setup: Students spaced arm's-width apart in staggered lines, everyone facing the same wall so nobody collides moving down the mat.
How it works: Two minutes general: jog the mat edge, backwards jog, side shuffle. Then the movements that ARE tonight's lesson, one length each, twice through: shrimps (hips off the floor, push off the top foot), bridges (heels close, hips high, look over one shoulder), technical stand-up, and seated guard sit-ups with a reach. Name the connection out loud: every one of these appears inside tonight's technique.
What to say
- “Shrimp off your foot, not your elbow — the hips do the escaping.”
- “Bridge to your shoulder, not your neck.”
- “Slow and correct beats fast and hollow — week one habits last years.”
Easier
Half-lengths; bridges without the shoulder turn.
Harder
Add a second lap of shrimps at the end, eyes closed for feel.
Technique of the Day — Posture & the Knee-Wedge Guard Break
Setup: Pairs, one person sitting into closed guard around the other, who starts kneeling. Demo twice at full view — once at speed, once slow with the steps numbered aloud.
How it works: Tonight's fight is simple: the person on top builds posture inside the closed guard, then breaks the guard open. Walk the room between demos; you are looking for straight backs and patient hands. Nobody passes tonight — the win is posture held and ankles unlocked.
The technique, step by step
- Kneel heavy: sit back on your heels, knees wide under their hips.
- Straighten your spine and look at the wall behind them — head up ends the fight for your neck.
- Anchor your hands: both on their belt line (gi: grip the belt or both lapels together; no-gi: palms flat on the hip bones), elbows locked inside their thighs.
- Stand your posture without standing up: chest tall, weight through your hands so they cannot sit up into you.
- Slide your right knee to the middle line, wedging under their tailbone.
- Push your left knee back and to the side, straighten your body slightly, and press their bottom leg open with the wedge — ankles uncross, guard is broken.
Key details
- Your hands pin their HIPS, not their chest — chest pressure invites armbars later; hip pressure never expires.
- The knee wedge lifts their tailbone off the mat a few centimetres; crossed ankles cannot survive that angle.
- Break with your whole body leaning back, not by pulling with your arms.
Common mistakes
- Bending the elbows and leaning forward — the moment your head drops below your hips, you're playing THEIR game.
- Rushing the knee wedge before posture is set — you'll get swept sideways and learn why order matters.
What to say
- “Posture first, always — nothing works from a bent spine.”
- “Elbows inside their knees, not flared into their armpits.”
- “Slow is smooth: the guard opens because your structure is right, not because you're strong.”
Easier
Guard player keeps ankles crossed loosely and gives no resistance at all.
Harder
Guard player may hunt wrist grips (but not sit up) — top must clear them and rebuild posture first.
Drilling
Setup: Same pairs, spread so no pair can roll into another. Coach calls the round changes for the whole room.
How it works: Three rounds of two minutes each way, resistance building each round: round one, guard player is a mannequin — top rehearses the full sequence on repeat. Round two, guard player resists at about a quarter — enough to make the details matter. Round three, half resistance — guard player may break posture down and hunt grips, top must recover posture and finish the break. Reset instantly after each success; reps beat drama.
Rounds: 3 × 2 min each way · resistance 0% → 25% → 50%
What to say
- “Count your clean reps, not your fast ones.”
- “If the break stalls, the error is almost always two steps earlier — rebuild posture.”
- “Guard players: honest resistance is a gift; being a boulder teaches nobody anything.”
Easier
Stay at mannequin resistance all three rounds — week one has no prizes for chaos.
Harder
Round three at three-quarter resistance for experienced pairs only.
Positional Rounds
Setup: Class splits into pairs across the mat; call all starts and stops yourself. Everyone begins in the same position: closed guard, top player postured.
How it works: Two-minute rounds from closed guard. Top wins by breaking the guard open and clearing the crossed ankles. Bottom wins by breaking the top player's posture down for three seconds, or by sweeping. Any win or stalemate: reset to the start position, go again until time. Rotate partners every round — three or four rounds depending on class size. Finish with thirty seconds where everyone just holds perfect posture, no fight, to burn in the feeling.
Rounds: 3–4 × 2 min · rotate partners each round
What to say
- “Wins are quiet — reset and go again; the round is the teacher.”
- “Top players: the moment posture bends, stop fighting forward and rebuild.”
- “Nobody is passing tonight — break, reset, repeat is the whole game.”
Easier
Ninety-second rounds; bottom player may not sweep, only break posture.
Harder
Top player must break AND put one knee through to combat base to win the round.
Next week builds on this: Week 2 — passing the open guard. The guard you broke open tonight is exactly where next week begins.
Slow Down & Bow Out
Setup: Circle up seated, backs tall.
How it works: Neck rolls, seated forward fold, hip stretch each side, wrists and fingers — 20 seconds each. Recap the one sentence that matters: posture first, always. Line up, bow out, mats wiped before anyone leaves.
Ask the class: Ask the room: when your posture broke, what had gone wrong just before? Take two answers — they'll both be 'my elbows came out' by the third week.
Next week builds on this: Week 2 builds directly on the break you drilled tonight.
