Yes, for the margins of a workout but not the workout itself. A coach should write the session; AI can draft scaling ladders and whiteboard notes from it, provided the coach checks every line for units, movement standards, intended time window and safety before anything reaches the whiteboard.
The checking matters because an assistant produces confident, tidy tables whether or not the numbers are right. Slips to look for: a load in pounds sitting in a column of kilograms, a scaled option that asks for more skill than the prescribed (Rx) movement, and a version that would take twice as long as the workout was meant to. None of these shows up unless someone who knows the athletes reads each cell.
The coach writes the session; the assistant writes the margins
CrossFit programming for a week of classes depends on things an assistant doesn't have: what the gym did last Tuesday, which athletes are returning from a break, how many rigs and rowers you own, where the roof gets low. A generated workout can look plausible and still stack the same pattern three days running, because nothing in the tool knows your week. So the session stays yours.
What you can hand over is the work that comes after the workout exists and is tedious to produce by hand:
- Scaling ladders for each movement, in the same layout every day.
- Whiteboard notes: intent, pacing, a checkpoint, stop signs.
- One coaching cue and one common fault per movement.
- A kit list and a set-up order for the person opening the gym.
- A one-page briefing for a cover coach.
- Plain-language versions of the above for members who read the workout at home.
The standard to hold the output to comes from CrossFit's own coaching material. Its article on hitting the stimulus says each workout has an intended stimulus to preserve (the effect it is meant to have, such as a sprint or a steady grind), and gives a rule of thumb for judging it: set the slower finishing time at double the fast time. Its article on scaling says lowering load, reps or duration may be enough, that wholesale elimination of a movement is rarely a useful early step, and that swapping in a different movement, or dropping one, comes last. Put that order into the prompt and you have a reviewer's checklist as well as an instruction.
What to paste in: your standards, your kit and your time window
The more of your own gym the assistant is given, the fewer things it invents. Four inputs do most of the work: the workout, the intended finishing window, the equipment you actually own, and your movement standards. Here is a filled-in prompt for the workout used in the rest of this tutorial; swap the bracketed part and the numbers for yours.
You are helping a CrossFit coach prepare scaling options. I write the workout; you draft the support material. I will check every line.
WORKOUT
4 rounds for time: 12 thrusters 43/30 kg, 10 pull-ups, 8 box jump-overs 60/50 cm. Cap 18:00.
Intended stimulus: fast, steady rounds. Fastest athletes finish in about 9 minutes; the slowest should land near 18.
CLASS
14 athletes, mixed ability: 2 beginners, 8 intermediate, 4 experienced. No names or health details.
EQUIPMENT
Barbells 20 kg and 15 kg; bumper plates plus change plates down to 0.5 kg; dumbbells 7.5, 10, 15 and 20 kg; boxes 60, 50 and 40 cm; a rig with 8 pull-up positions; 6 pairs of rings.
MY MOVEMENT STANDARDS
[paste your gym's standards for the thruster, pull-up, box jump-over and ring row]
TASK
1. Draft a table: movement, Rx, Intermediate, Scaled, Foundations.
2. Scale in this order: load, then reps, then a progression of the same movement. Substitute a different movement only as a last resort, and say why.
3. Keep every column inside the same finishing window. If an option would take longer, say so.
4. Use only the equipment and standards above. Do not invent standards.
5. Use kilograms and centimetres, with pounds or inches in brackets for Rx only. Convert nothing I did not give you.
6. After the table give one coaching cue, one common fault and one stop sign (a reason to move to an easier column) per movement.
7. List anything you were unsure about at the end.
Rule 4 is the one that earns its keep. Without a kit list, an assistant can easily prescribe a 45 cm box or a 12.5 kg dumbbell that your gym has never owned, and the first you will know is when an athlete asks where it is. Rule 7 is useful in a different way: a model that is made to list its doubts may admit that it guessed the standard for a ring row, which tells you where to look first.
Keep the standing parts (standards, kit list, ladder layout) in a Project, which both ChatGPT and Claude offer and which keeps instructions and files between chats. Then each day's prompt is only the workout, the window and the class mix. Don't paste names, injuries or medical details; describe the class by category, as above.
A worked draft: thrusters, pull-ups and box jump-overs
Start with the window, because every scaled option is judged against it. The coach's workout is four rounds of 12 thrusters, 10 pull-ups and 8 box jump-overs: 30 reps a round, 120 in all. If the fastest athletes finish in about 9 minutes, CrossFit's rule of thumb puts the slow end at about 18, which is the cap. Spread over four rounds, that gives two numbers worth writing on the board: roughly 2:15 a round at the fast end and 4:30 at the slow end. An athlete who reaches the end of round two after more than 9:00 is heading past the cap and should move to an easier column for rounds three and four.
The assistant's first draft looked like this (illustrative output, with the errors the coach found):
| Movement | Rx | Intermediate | Scaled | Foundations |
|---|---|---|---|---|
| Thruster (12) | 43/30 kg | 35/25 lb | 25/15 kg | Empty barbell |
| Pull-up (10) | Chin over bar, strict or kipping | Banded pull-up | Kipping banded pull-up | Skip; do 10 push-ups |
| Box jump-over (8) | 60/50 cm | 45/35 cm | Step-over 45/35 cm | Step-up 30 cm |
It also proposed an 18-minute cap in one place and "expect 12 to 20 minutes" in another. Reading it line by line, the coach marked six problems:
- Unit slip. "35/25 lb" in the Intermediate column is about 16/11 kg, lighter than the Scaled column. The ladder no longer goes in order. Fix: 35/25 kg.
- A skill that costs more than the Rx. Kipping banded pull-ups for the Scaled column ask for a technical skill that beginners don't have. Fix: ring rows at a moderate body angle, 10 reps.
- A movement dropped outright. Skipping pull-ups removes the pulling pattern, and push-ups are a different one. Fix: ring rows with the body more upright, 8 reps, because CrossFit's guidance prefers a progression to a deletion.
- Heights the gym doesn't own. 45/35 cm and 30 cm don't exist among 60, 50 and 40 cm boxes. Fix: 50/40 cm jump-overs, then a jump up with a step down, then a 40 cm step-over.
- Two finishing windows. "12 to 20 minutes" contradicts the 9 to 18 the coach set. Fix: delete it; the window is the coach's.
- No rep reduction anywhere. The draft never lowered a rep count, so the easiest column still meant a full round of 12, 10 and 8. For beginners, lowering reps is the first lever, so Foundations gets 8 thrusters, 8 ring rows and 6 step-overs a round.
The ladder after review:
| Movement | Rx | Intermediate | Scaled | Foundations |
|---|---|---|---|---|
| Thruster | 12 at 43/30 kg | 12 at 35/25 kg | 12 at 25/15 kg | 8 with an empty barbell |
| Pull-up | 10, chin over bar | 8 banded, light band | 10 ring rows, moderate angle | 8 ring rows, more upright |
| Box jump-over | 8 at 60/50 cm | 8 at 50/40 cm | 8 jump up, step down, 50/40 cm | 6 step-overs at 40 cm |
Count the corrections: six, in a draft of twelve table cells and two sentences. The assistant saved the typing, and the coach's pass caught the parts that could have hurt someone or left them standing at the rig with nothing to do. This is why review has to be a deliberate step with its own time, not a glance.
Seven checks to run on every line
Do these in order, with the draft printed or on a second screen, and tick each one rather than skim:
- Units and arithmetic. Read every number against its column. If you want a sum to hand, 95 lb divided by 2.2 is about 43 kg, and 65 lb is about 30 kg. Check that each column goes lighter as you move down the ladder, which would have exposed the 35/25 lb slip at once.
- Standards. Does each movement match your gym's written standard, including the scaled ones? An assistant may describe a ring row, a box step-over or a hang power snatch in a way that differs from how you teach it.
- Window. Would a typical athlete in each column land inside the finishing window? Count reps per round and judge the pace. If the Scaled column needs 3:50 a round, the window holds. If it needs 6:00, it doesn't.
- Skill under fatigue. Scaled options should be simpler to perform, not just lighter. A technical lift such as a squat snatch, offered as a scaled thruster, asks for more skill under fatigue, not less. Choose the simpler movement, not just the lighter bar.
- Volume against what athletes are used to. Forty pull-ups across a session is a large jump for someone who manages three strict ones. A big step up in unfamiliar work is a risk in its own right, so cut reps before you cut anything else.
- Space and kit. Fourteen athletes, eight rig positions, six pairs of rings: can everyone work at once, or is there a queue? A queue changes the stimulus. Check box and dumbbell counts against the class cap.
- Boundaries. Is anything in the draft a decision about a person rather than a movement? Injuries, pregnancy, medical conditions and under-18s are yours to handle with the athlete, and where needed their clinician. Cut any line that tries.
For a second opinion on the workflow side, the tutorial on using ChatGPT safely for client programmes covers the one-to-one version of the same checks.
The week map: patterns the assistant cannot see
A substitution that looks sensible on its own can duplicate work already on the schedule, so look at the surrounding days before you accept one. An assistant given one workout can't do that, so make a week map and check the draft against it. An illustrative week:
| Day | Session | Heavy on | Flag for scaling |
|---|---|---|---|
| Monday | Back squat 5 x 5, short run intervals | Legs | Tempo option for squats |
| Wednesday | Push press, wall balls, handstand push-up progressions | Overhead, shoulders | Cap overhead reps for beginners |
| Thursday | Deadlift, toes-to-bar, rowing | Grip, hips | Grip is tired by Friday |
| Friday | Thrusters, pull-ups, box jump-overs | Overhead, grip, legs | Thrusters follow Wednesday; pull-ups follow Thursday's grip work |
| Saturday | Partner workout: row, burpees, dumbbell work | Whole body | Keep scaled partners on the same pace |
On this map Friday has two warnings: overhead work two days after Wednesday's push press, and pull-ups the day after toes-to-bar. The coach's response isn't something an assistant would volunteer: start Foundations at 6 ring rows rather than 8 for anyone who struggled on Thursday, and keep the two beginners on the empty bar for thrusters even if they feel fresh. If you paste the week map into the prompt, the assistant can flag overlaps too, but treat its flags as prompts for your own judgement, not as the check.
Whiteboard notes and a cover-coach brief
Whiteboards are small and athletes read them mid-warm-up, so the note has to be short. This is the final note for the Friday workout after the coach's edits, using the 9:00 checkpoint from the quick sum:
FRIDAY: 4 rounds for time
12 thrusters 43/30 kg
10 pull-ups
8 box jump-overs 60/50 cm
Cap 18:00
INTENT: fast, steady rounds. Rx about 9-14 min. Nobody slower than 4:30 a round.
PLAN: thrusters in two sets of 6 at most. Pull-ups in two sets. Step down off the box.
CHECKPOINT: past 9:00 after round 2? Move down one column for rounds 3 and 4.
Intermediate Scaled Foundations
Thruster 35/25 kg 25/15 kg empty bar x 8
Pull-up light band x 8 ring row x 10 upright ring row x 8
Box 50/40 cm jump jump up, step down 40 cm step-over x 6
STOP SIGNS: sharp joint pain, dizziness, form gone. Tell a coach and move down a column.
Ask for the board version as a separate request, with a line limit, and keep the longer notes (cues, faults, strategy) for the coach's own sheet. Nobody reads a paragraph on mindset at 06:00. A prompt that does it:
Now write the whiteboard version only. Maximum 14 lines, plain text, no headings and no motivational advice. Include: the workout exactly as I wrote it, the intent in one line, a pacing line, a checkpoint based on the 4:30-a-round limit, the ladder as three short columns, and one line of stop signs. Do not change any number I gave you.
A cover-coach brief is the other note worth drafting, because that is when a gap in your own knowledge costs most. An illustrative brief for the same class:
Friday 06:00, 14 booked: two beginners, one athlete back from a break who will tell you what they can do (check in before the warm-up), four experienced athletes, the rest intermediate. Kit: 8 pull-up positions, 6 pairs of rings, boxes at 60, 50 and 40 cm. Standards: chin over bar for pull-ups; ring rows with a straight body; step down from boxes, don't jump down. Hazard: low ceiling over the end rig, so no kipping there. Warm-up: 8 minutes of rowing and barbell thruster practice. If the class runs behind, cut round four for the Foundations column and keep the cap.
Every line in that brief comes from your own notes. The assistant's job is to tidy and order them, and the coach's job is to confirm that the hazard line is still true before a stranger relies on it.
Strength days: let athletes bring the numbers
Scaling a strength session is mostly about load and control, and the assistant doesn't have anyone's numbers. Don't give them to it. Write loads as a percentage of the athlete's own recent best set, or as "work up to a heavy set of five", so the athlete does the sum with figures only they know. For a five-by-five back squat, an athlete whose best set of five is 80 kg works at 75%, which is 60 kg. The whiteboard says 75%; nobody has pasted a member's lifting history into a chat window.
For athletes who lack the control for the load, a tempo option keeps the stimulus. CrossFit's Pro Coach material lists tempos such as 3-1-X-1 (three seconds down, a one-second pause at the bottom, an explosive drive up, a one-second pause at the top) as a scaling tool that adds time under tension, and an assistant will draft that kind of line well if you ask for it: "three-second lowering, one-second pause, same load as the group below". Review it the same way as any other line, because "same load" has to be right for the person holding the bar.
Two other strength-day details deserve a look in any draft. The assistant may give every athlete the same warm-up sets, which ignores that a beginner's working weight is a veteran's warm-up. And it may suggest adding load each week without any ceiling. Tell it the progression rule you actually use, whether that is small weekly jumps or repeating a weight until it feels easy, and make it quote that rule back.
Where the assistant has to stop
Some decisions are not the assistant's, and not entirely the coach's either. An athlete who is pregnant, recovering from surgery, taking medication that affects exercise or in pain on a movement needs a conversation with the athlete and, where appropriate, their clinician. Don't ask an assistant for "a workout for someone with a bad shoulder". The tutorial on client check-ins without medical advice draws the same line for one-to-one coaching, and a waiver or liability wording question belongs with a solicitor; see the tutorial on gym waivers for what to take to one.
One safety flag deserves a place in your coaching notes. Severe exertion is a recognised cause of rhabdomyolysis, a breakdown of muscle tissue whose signs include muscle pain or stiffness, weakness and dark, red or cola-coloured urine. A coach can't diagnose it on the gym floor and shouldn't try. An athlete with those signs after a session should get medical advice promptly. It's a reason to be wary of sudden jumps in unfamiliar volume, which is check five above, and to say so on the whiteboard when a workout is unusually high in reps.
Equipment is the other boundary. The assistant can draft a kit list for a workout, but it can't tell you whether the rig bolts are tight or the rower chains are worn. If a workout leans on a piece of kit that has been temperamental, the equipment maintenance checklist tutorial is the place to start. Finally, privacy: keep names, medical details and anything an athlete told you in confidence out of the prompt. The class mix by category is all the assistant needs.
Four weeks in: what to count and what to log
Pick two numbers and one question, and track them for four weeks. First, the share of each class that finished inside the intended window; CrossFit's own framing is that scaling load, reps and movements should keep most athletes in the target range, so that share is your measure. Second, how many athletes changed column mid-workout: a few is healthy, most of the class means the Rx or the ladder was off. The question, asked of a handful of regulars after class, is "did that feel like the same workout as the Rx?" If the scaled athletes say no, the ladder preserved the load but lost the intent.
Keep a short log of the errors you caught. If the same kind turns up twice, such as a unit slip or an invented box height, add a rule to the standing prompt. After a month the log is also your answer to whether the whole exercise is worth it: if you are catching nothing, you may be reviewing too lightly; if you are rewriting most of every ladder, the prompt needs more of your standards in it. Either way the workflow stays the same: you write the session, the assistant drafts the margins, and nothing reaches the whiteboard until a coach has read every line.
Questions coaches ask before trying this
Can I paste last week's programming in for context?
Yes, if it is your own programming and it contains no member names or health details. Keep it in a Project (ChatGPT and Claude both offer them) so the standing instructions and files stay put. Business plans don't train on your content by default, while consumer plans have a model-training switch in the privacy settings. Check which you are on before pasting anything you would not want shared.
Should members be told the notes were drafted with AI?
There is no rule I can point to for gym whiteboards, so honesty is the safer default. If a member asks, say that a coach wrote the workout, an assistant helped draft the scaling options and the coach checked every line. What members care about is that a qualified person stands behind the notes. Ask your insurer or adviser whether your cover or terms say anything on the subject.
How many scaling tiers should a ladder have?
Three beyond Rx is plenty: Intermediate, Scaled and Foundations. Every extra tier is another column to check for units and standards, and another thing a coach must remember while watching fourteen athletes. If you find yourself needing a fifth tier, the workout probably asks for too much skill and the fix is to change the workout.
Is a free plan enough for this job?
For one workout, usually yes: a ladder is a short task. Free-tier limits change often, so check yours. A paid plan of about $20 a month gives more room if you want to draft a whole week in one sitting. The real cost is review time, so budget more minutes for checking than for generating.
