12.1 Class Introduction and Expectation Setting

The 5:45 a.m. cycle room is already loud with shoe cleats. Eighteen bikes are claimed. You have maybe ninety seconds before the first track. Independent OpenExamPrep CGFI teaching treats that window as Domain 3 work, not as a personality contest. The published 2020 Job Analysis names an instruction task candidates meet every time they take a room: introduce yourself and the class. The facts the task expects are your name, the format, the duration, and the equipment people need in their hands — or clipped to the bike — before the work starts. Safety notes, intensity options, and where the exits and water are belong in the same opening because they are expectations people can still act on while they can hear you.

This is live instruction. It is not movement prep. Chapter 7 already drew that line: a welcome speech does not raise tissue temperature. This section is about what you say, how long you take, and which stems fail when an instructor skips the opening or turns it into a brand monologue.

Name, Format, Duration, Equipment

Say who is teaching. "I'm Maya" is enough. Regulars still deserve a name on the days a substitute walks in. A five-minute origin story is not the introduction task; it is a delay.

Name the format in the language of the work, not only a marquee nickname. "This is a 45-minute indoor cycle class with seated and standing intervals" tells a first-timer what they consented to. "Fire Friday" without the actual work is marketing. If the club calendar said yoga flow and you run a jump block, you have a consent problem, not a branding win.

State duration, including that there will be a come-down. People budget childcare, parking, and the next class knocking on the door. "We have 50 minutes on the clock, including transition" is a time budget. Starting late and never saying what remains is how someone walks out mid-interval thinking the hour is over.

List equipment now. "Mat, a light set, and a medium set. If you only found one pair, keep them — I'll give a body-weight option." Announcing a kettlebell after the first work song is how shins and iron meet. If inventory is short, the intro is when you license substitutions, not when you apologize for the next forty minutes.

Missing the four introduction facts is a classic Domain 3 miss. A charismatic "Let's crush it!" with no duration or equipment list is motivation without an introduction.

Safety Notes Without Diagnosing

Safety notes are boundaries, not a clinic. Independent CGFI study by OpenExamPrep covers what a group instructor can say while the room is still assembling:

• Bags and bottles live where aisles stay clear.
• How to flag you: hand raise, step to the wall, sit the bike, pause the stream and stop.
• Sharp, radiating, or joint-specific pain is a stop. It is not a "push through" cue.
• New participants may take the first block at rehearsal intensity.
• You do not diagnose. Chest pain, unshakable dizziness, or a medical emergency is facility emergency action plan territory and referral — not a treatment plan on the mic.

Do not use the intro to sell supplements, guess an injury from the door, or promise that this hour "fixes" a condition. Those lines wander out of instruction and into professionalism and scope, which later chapters treat as Domain 4.

Intensity Options as Expectation, Not a Rescue

Name that options exist before people are gasping. "I'll show two versions of the squat: sit-to-stand from a chair, and a loaded goblet. Both count." That sentence is expectation-setting. Waiting until someone is failing a jump in song three to whisper "or you can march" is a correction, and it often arrives after pride and joints have already taken a hit.

Options you can preview without demoing every regression:

• Impact — march versus hop
• Complexity — step-touch versus a turn
• Load — body weight versus dumbbell
• Range — the hinge they own versus the deepest hinge in the room
• Position — standing versus kneeling (later chapters unpack in-class modifications)

The intro does not need a full regression catalog. It needs to license choice so mixed-level people are not performing a test they did not sign up for.

Exits, Water, and the Room as a Safety Map

"Where are the exits and water?" sounds mundane until a fire alarm, a medical event, or a first-timer who has never stood in Studio B. Point. Do not mumble toward a wall. In a pool, name the ladders and the shallow end. Outdoors, name the weather meeting point. Virtual: you cannot point at their hallway, so tell them to know their own exit, keep water in reach, clear the floor, and pause if a move feels wrong — you cannot see their coffee table.

Hydration access is logistics. "Fountain in the corridor; bottles at the back wall so nobody trips." If the HVAC is stuck on heat, say so and tell people they may drop intensity. That is still expectation-setting.

Keep the Intro Short on Purpose

A working heuristic: about 60–90 seconds for a regular hour; up to about two minutes when the room is full of new faces or the format is unusual. That is a teaching range, not an unpublished official stopwatch. Steal from movement prep and you start cold. Skip the introduction task to "get more sweat" and the job-analysis task is simply undone.

Script skeleton — adapt it; do not recite it as liturgy:

1. Welcome and your name
2. Format in plain language
3. Duration, including a come-down
4. Equipment checklist and the short-inventory plan
5. Safety: sharp pain equals stop; how to flag you; bags out of walkways
6. Options: more than one version; they choose
7. Exits and water, pointed
8. "Find your space; we start with movement prep."

Then stop talking and raise temperature.

Class-Floor Scenarios

Early cycle. Mic on. "I'm Alex. Forty-five minutes of indoor cycle, seated and standing intervals. If you're new, stay seated on the first standing cue and I'll show you. Water and restrooms in the hall; emergency exit is the glass door to the parking lot. Bottles to the right of the bike so we don't roll over them. Easy pedal to start." Playing a climb before duration exists is not an introduction.

Lunch-hour strength. "I'm Priya. Forty minutes of strength endurance, not a stretch class. Mat and two dumbbells. If the rack is empty, I'll give you a band or body-weight version — both are the class. Sharp joint pain: stop that move. Fountain by the front desk; exit is the door you came in." Then movement prep.

Livestream. Full body in frame. "I'm Sam. Thirty minutes of low-impact cardio. Mat, clear floor, water nearby. I cannot see your living room. If a move feels wrong, skip it. If you need to stop, stop. We start with a march."

Traps Items Like

Treating the intro as optional because the playlist is famous. Naming only a nickname format. Equipment surprise after the music is loud. A safety speech that is actually "don't be lazy." Skipping exits and water for regulars. A ten-minute autobiography. Diagnosing from the stage. This independent OpenExamPrep chapter teaches the published 2020 introduction task as job knowledge; it is not an AFAA or NASM course, review, or partnership.
