Kit: One mat per member, a folded towel or small cushion each for heads and knees. Nothing else — precision is the equipment.

Warm-up5 min

Find Neutral

RPE 1–2

Setup: Mats in tidy rows with walking aisles between — you will spend the whole class moving along them. Everyone on their back, knees bent, feet hip-width.

How it works: Teach the two ideas the next 25 minutes run on. Neutral spine: rock the pelvis to flatten the low back, then over-arch it, then settle in the quiet middle — the natural small gap under the low back. Then the breath: in through the nose wide into the ribs, out slowly through pursed lips while the deep belly gently draws in, like hugging the spine from the inside. Six breaths in neutral, then arm floats — one arm reaches overhead on the exhale, ribs staying heavy, alternating ×6.

Common mistakes

Skipping the neutral-spine teach to save time — every later exercise is built on it; the five minutes pays for the twenty-five.

What to say

“Neutral is the quiet middle — not pressed flat, not arched proud.”
“Exhale like fogging a mirror slowly; feel the waist gently narrow.”
“Arm floats: if the ribs pop up, the arm went further than the core agreed to.”

Easier

Cushion under the head; smaller arm float, elbows soft.

Harder

Float both arms together while the ribs stay down.

Workout9 min

Supine Series

4 moves · ~2 min each · breath-pacedRPE 3

Setup: On backs in neutral, hands resting on the hip bones where they can feel any wobble.

How it works: Four exercises, all owned by the exhale. Toe taps: knees over hips at ninety degrees, lower one toe to the mat on the exhale, return on the inhale — ×8 each side. Dead bugs: opposite arm and leg reach long on the exhale, return — ×6 each side. Shoulder bridge: peel the spine up bone by bone to a line from knees to shoulders, three breaths at the top, roll down slower than you went up — ×3. Single-leg stretch shape: one knee drawn in with both hands, other leg long and hovering or resting, swap with control — ×8 total.

Common mistakes

Letting the group race your count — pause, reset the breath, restart slower.
Hands behind heads yanking necks — hands stay on the hip bones this block.

Rounds: 1 slow circuit

What to say

“The low back stays quietly in neutral — the moment it arches, shorten the movement.”
“Exhale on the effort, always — the breath and the movement are one thing.”
“Bridge down like a zip closing from the chest — one bone at a time.”
“Slow is the progression; speed is the escape hatch.”

Easier

Toe taps with a smaller range; dead bugs moving the legs only; bridge without the hold; long leg rests on the mat.

Harder

Both toes tap together; dead bugs with a two-second reach; single-leg bridge for the last rep, three counts per side.

Workout8 min

Side & Prone Series

Side ~4 min · prone ~4 minRPE 3–4

Setup: Mats turned side-on to your aisle so you see every spine in profile. Towels ready under hips and foreheads.

How it works: Side-lying leg lifts: body in one long line, bottom arm long under the ear, top leg lifts to hip height and lowers with control — ×10, then 10 small circles each way, then swap sides. Side plank on the forearm and knees: two holds of 15 seconds each side, hips proud. Then prone: forehead on the towel, arms by the sides — back extensions, hovering the chest a few centimetres on the exhale, ×8, followed by swimming arms — opposite arm and leg hover and swap, slow, ×8 total.

Common mistakes

Skipping the mat turn — side-on you catch every sagging hip; front-on you catch none.

What to say

“Side lifts: the waist stays long — lift the leg, not the hip into the ribs.”
“Side plank: push the floor away and take the hips forward — a straight line, seen from above.”
“Extensions are a hover, not a cobra — length along the floor before height off it.”
“Eyes down on prone work; the neck is part of the spine, keep it in the line.”

Easier

Leg lifts with the top knee bent; skip the side plank and repeat lifts; extensions with hands resting under the shoulders.

Harder

Side plank on forearm and feet, 20 seconds; extensions with arms in a Y hover.
