Kit: Mats, water. No weights, no timer beeps — you call every interval with your voice tonight.

Welcome In

5 × 45s gentle buildersRPE 2–3
The whole night — gentle waves of work and rest, never a wallhellohomeWork bumps stay small on purpose —rests are long and never rushedrest gaps stay wide all night

Setup: Greet every person at the door and learn names — in a beginners class this is programming, not politeness. Mats in a loose semicircle facing you, nobody stuck in a back row.

How it works: Start with the promise, said plainly: nothing tonight requires jumping, nobody will be singled out, and every move has two versions with the gentler one demonstrated first. Then five minutes of easy movement — walking on the spot, shoulder rolls, side-steps, gentle squats to a knee-height tap, arm swings — 45 seconds each, chatting as you go. Explain HIIT in one line: short bursts of working a bit harder, short rests, repeat — that's the whole secret.

What to say

  • The gentler version is the main version tonight — the other one is just there if you're curious.
  • If you can chat a little during the work, you're doing it exactly right.
  • Nobody watches anybody here — everyone's too busy breathing.

Easier

Every warm-up move at strolling pace; squats become sit-to-stand on a bench if knees prefer.

Harder

A touch more depth in the squats for anyone visibly comfortable.

Round One — Learn the Rhythm

3 × 3 moves × [30s work / 30s rest] + 1min walkRPE 5

Setup: Three moves only, all rehearsed in the warm-up family: squats to a tap, wall or knee push-ups (show both), marching with driving arms. Your voice is the timer.

How it works: Three laps of the three moves: 30 seconds of work, 30 seconds of full rest, called warmly by voice — no beeping clock on a first night. The work instruction is deliberately modest: move a bit quicker than the warm-up, that's all. Use the rests to teach one thing at a time and to say names. After the last lap, a full minute of walking and water — and point out loud that they have just done HIIT, nine rounds of it.

Rounds: 3 laps

What to say

  • A bit quicker than the warm-up — that's the only assignment.
  • Rest means rest; standing still and breathing is doing it right.
  • That thing you just did three times? That was HIIT. You're doing HIIT.

Easier

Work 20 seconds of each 30; sit-to-stands instead of squats.

Harder

Squats without the tap, push-ups from the floor — offered quietly to individuals, never announced.

Round Two — A Little Braver

2 × 4 moves × [30s work / 30s rest] + 90s walkRPE 5–6
The room — semicircle of mats, coach in front, nobody in a back rowSemicircle: everyone sees you, you see everyone

Setup: Same three moves plus one new guest: standing knee drives with a reach. Four moves, same voice-called clock.

How it works: Two laps of the four moves, 30 on, 30 off. The pitch: same rhythm as round one, one new move, and permission to be five percent braver — a number small enough that nobody fears it. Watch for the first-timer tells — held breath, worried faces at the new move — and fix them with humour and your own demo, never by correcting someone by name in front of the room. End with 90 seconds of easy walking; announce the finisher as a victory lap, not a test.

Rounds: 2 laps

What to say

  • Five percent braver than round one — no more, that's next week's job.
  • Breathe out on the effort; if you're holding your breath, slow down and it comes back.
  • New move, same rule: your pace, your version, your class.

Easier

Repeat round one's three moves and skip the knee drives entirely.

Harder

Knee drives with a quicker rhythm for the visibly comfortable.

The Victory Lap

2 × 2 moves × [20s work / 40s rest]RPE 5

Setup: One last mini-round, framed as a celebration. Pick the room's two favourite moves from tonight — ask them, let them vote by cheering.

How it works: Four rounds total: 20 seconds of move one, 40 seconds rest, 20 seconds of move two, 40 seconds rest, repeated once more. Twenty seconds is short enough that everyone finishes strong, which is the entire design — first-timers must leave on a completed rep, not a collapse. Count the final ten seconds down together and applaud the room. Applause in week one becomes attendance in week two.

Rounds: 4 efforts

What to say

  • Twenty seconds — you could do this in your sleep now.
  • Finish the last one like you're posing for a photo.
  • That's the class — and you did every single round of it.

Easier

Fifteen-second efforts with the same long rests.

Harder

None tonight. The victory lap is a victory lap for everyone.

Land Softly

RPE 2 → 1

Setup: Music at its warmest, lights up. Mats stay where they are.

How it works: One minute of slow walking and shoulder rolls, then three stretches everyone can do: hamstring reach with soft knees, quad stretch holding a wall or mat neighbour's shoulder for balance (it breaks the ice), chest opener with hands behind the back — 40 seconds each. Close by naming what happened: they did nineteen work intervals on their first night. Tell them week two is this exact class with one small twist, and say you'd love to see them there.

What to say

  • Stretch until it feels nice, not until it feels like effort.
  • Nineteen rounds on night one — write that down somewhere.
  • Same class next week, one small twist — come find out what it is.

Music: Friendly ~122bpm throughout, nothing aggressive — first-timers read the music as a forecast of what's coming. Save anything fierce for their fourth week.
