Yes, AI can turn your session rules into a plain-language personal trainer contract in about an hour. A solicitor must still check the cancellation and refund terms, pack expiry, injury and health disclosure, and the liability limits, because those clauses decide who pays when a session is missed, a pack goes unused or a client is hurt.
AI writes the sections every template has. What it cannot see is your price list, your insurance policy or what the law where you work lets you exclude, which is why the same handful of clauses come back from legal review with changes. Nothing here is legal advice.
Write your six decisions down before you open the AI
Ask an assistant for "a personal trainer contract" and you will get a cancellation window, a pack expiry date and a liability paragraph, all chosen by the model and none of them yours. Reverse the order. Decide first, then let it write. These are the choices for an illustrative solo trainer with 25 clients:
- Cancellation: 24 hours' notice; later than that, the session is lost.
- Packs: ten sessions for $600 ($60 each, against $75 for a single session), valid for 12 weeks.
- Health: the PAR-Q+ completed before the first session, and again when anything changes.
- Injury: the client tells me within a day; sessions pause, and pack expiry extends by the length of the pause, up to eight weeks.
- Insurance: public liability and professional indemnity in place; limits to confirm with the broker.
- Ending: monthly arrangements end on four weeks' notice; packs follow the refund rule.
Draft a personal trainer client agreement in plain language, about two pages, using only these decisions:
[paste the six decisions]
Rules:
- One short numbered clause per decision, plus a clause on payment and one on data.
- Where I have not decided something, write [OWNER DECIDES: what] instead of choosing.
- Do not state what the law requires or allows. Mark any sentence that depends on local law with [SOLICITOR].
- Do not rewrite or summarise the PAR-Q+. Refer to it by name as a form the client completes.
- Finish with a list of the markers and one question for each.The draft that comes back reads well and looks finished. Look at what it did to the packs clause (illustrative excerpt):
4. Packs. The Client may buy a pack of ten sessions for $600. Packs are valid for eight weeks from the date of purchase. Unused sessions expire at the end of that period and are not refundable. Packs are not transferable. If the Client ends this agreement, no refund will be given for unused sessions.
Five sentences, and the model quietly made four decisions for you. Expiry is eight weeks, where you chose 12. Refunds are ruled out, which you never decided. Transfers are ruled out, which you never decided either. And there is no pause for illness, where yours allows up to eight weeks. Every one of those reads as ordinary contract language, which is why they slip through. When you review an AI draft, hunt for numbers and absolutes ("not refundable", "in no event", "at all times") and compare each against your own list.
Cancellations: the 24-hour rule and what it is worth
A typical first-draft line (illustrative): "Sessions cancelled with less than 24 hours' notice are charged in full." It is a fair start, and three details change how it behaves in practice.
First, what counts as notice. A voicemail left at 11pm for a 6am session is not notice in any useful sense, so name the channel (the booking app, a text to one number) and say that notice is given when you receive it. Second, exceptions: illness, injury and genuine emergencies, with your right to ask for a short explanation. Third, your own cancellations: if you cancel, the client is offered a new time or the session is returned to their pack, and for outdoor sessions you say what happens in bad weather.
The money matters too. Three late cancellations a week that you cannot refill cost 3 times $75, which is $225 a week or $900 over four weeks. Now suppose you refill one slot in three. The average loss per late cancellation is two-thirds of $75, which is $50, so a full $75 charge sits $25 above it. A solicitor will ask whether a full charge is a fair price for a reserved slot or an amount that works as a penalty, and the answer depends on where you work. Some trainers charge half for same-day cancellations and the full amount only for no-shows. Whichever you choose, the contract has to say it, and your booking tool has to be able to apply it; the tutorial on Vagaro for personal trainers looks at packs and bookings in one system.
Session packs: three refund rules and what each returns
Packs produce some of the most awkward conversations in a trainer's business, because the contract has to cover what happens to sessions nobody used. AI will write something like "packs are non-refundable and expire after eight weeks", which is neat and one-sided. There are three common alternatives, and the sums are quick. Take a client who buys the $600 pack, uses four sessions and then moves away:
| Rule | Refund to client | Trainer keeps | Question for the solicitor |
|---|---|---|---|
| A. No refunds, pack lapses | $0 | $600 | Is a term like this fair to an ordinary consumer where I work? |
| B. Pro rata at the pack price | 6 x $60 = $360 | $240 | Anything to add about timing of refunds? |
| C. Used sessions re-priced at the single rate | $600 - (4 x $75) = $300 | $300 | Is the re-pricing clear enough before purchase? |
Rule B is the simplest to explain and to defend. Rule C is often used because it protects the pack discount, but the contract has to state the single-session rate and the re-pricing at the point of purchase, not buried in a later paragraph. Rule A is the one a solicitor is most likely to question. Pair whichever rule you pick with the expiry: 12 weeks for ten sessions leaves two spare weeks, which is about right for a weekly client, but ask what happens when a client is ill or on holiday. The example trainer's answer is a pause that extends expiry by the length of the pause, up to eight weeks. Also ask your solicitor whether any rules on prepaid credits apply to packs where you work, and what the contract must say if it renews automatically. The tutorial on modelling session packs with AI helps you test the pricing before the wording is set.
Health disclosure: let the PAR-Q+ do the asking
Many trainers ask AI to write a health questionnaire into the contract. Don't. The PAR-Q+ already exists, and its owners are strict about how it is used. The form has seven questions and says to use the entire questionnaire, with no changes permitted. The PAR-Q+ Collaboration's terms go further: its written authorisation is needed before anyone modifies, adapts or translates the questionnaire, or builds it into a third-party electronic survey, app or website. That rules out two common shortcuts, asking AI to improve or shorten the questions and rebuilding them in an online form builder. Use the official version from the PAR-Q+ site, and ask for permission if you want it inside your booking software. Its own FAQ also warns that a personal trainer is not automatically a "qualified exercise professional" in the form's sense, so check the usage guidelines before describing yourself that way in the contract.
The contract should instead refer to the form by name: the client has completed the current PAR-Q+, will tell you promptly about changes in health, and understands that you may adapt or refuse a session if clearance is needed.
Two details are worth putting in your diary system. The form's declaration says clearance is valid for a maximum of 12 months and becomes invalid if the person's condition changes, so a client who completes it on 2 November 2026 needs a fresh one by 2 November 2027 at the latest, and sooner if anything changes. And where the person is below the legal age for consent, the form says a parent, guardian or care provider must also sign.
The classic AI slip here is the "good health" sentence (illustrative): "The Client confirms they are in good health and fit to exercise." Clients rarely know that, and a sentence that overstates what they know does not protect you. A better version says what actually happened:
The Client has completed the PAR-Q+ before the first session, has answered it truthfully, and will tell the Trainer promptly about any injury, illness, pregnancy or change in medication. The Trainer may adapt, pause or decline a session if clearance from a medical professional is needed.
A completed PAR-Q+ is health data. Keep it in your client system, not in chat threads, and never paste a real client's answers into an AI tool; use a blank form and an invented example when you test anything. The tutorials on intake forms and health data and on protecting client health data when using AI go through storage and consent in more detail.
Injury clauses: pausing, returning and what a contract cannot promise
Injury wording has three jobs: to tell the client about the risk, to set out what happens when they are hurt, and to keep you inside what a trainer can claim to do. AI is fine on the first and weak on the second and third.
Here is the sentence to expect (illustrative): "The Trainer shall not be liable for any injury, however caused." In many places you cannot exclude liability for injury caused by negligence at all, and a clause that tries may be struck out or treated as unfair to an ordinary consumer. The usual replacement is an acknowledgement rather than an exclusion:
The Client understands that exercise carries a risk of injury. The Trainer will take reasonable care in planning and supervising sessions and will stop any exercise that is causing pain.
Whether you add any limit beyond that, and what it looks like, is for the solicitor and your insurer. Two other clauses belong here. One covers pausing and returning after an injury: who tells whom, whether you ask for clearance from a medical professional before resuming, and how the pack expiry moves. The other keeps the scope honest: you are not providing medical treatment or nutrition prescriptions, and results are not guaranteed. AI tends to forget the second and invent the first, so read both closely. The tutorial on client check-ins without medical advice draws the line from the other side.
Five questions for your insurance broker
The liability clause sits on top of an insurance policy, and the contract must not promise more than the policy supports. Before the solicitor sees the draft, ask your broker:
- Does the policy cover accidents to clients (public liability) and mistakes in programme design or advice (professional indemnity), or only one of them?
- What is the limit per claim, and does my contract promise anything above it?
- Does the insurer expect clients to complete a health screening or sign an acknowledgement, and in what form?
- Are all my places of work covered: clients' homes, parks, a rented gym floor, online sessions?
- Which activities or group sizes are excluded, and whom do I tell when I add a new service?
Write the answers on one page and attach it to the pack for the solicitor. They explain why a clause is worded as it is.
Payment, price changes and ending the arrangement
The last clauses are the quiet ones, and they cause the slow-burning disputes. For payment, say when money is due (before the first session of a pack, or on a set day for monthly plans) and what happens when a card fails. If you take automatic card payments, the contract on its own is usually not the authority to charge: payment providers generally need the client's separate, recorded agreement to recurring or later charges, and the contract must describe that arrangement accurately. Monthly arrangements need a notice period, and the example trainer uses four weeks. If anything renews automatically, the contract must say so plainly and say how the client stops it. Price rises need notice, and the contract should say how much and how the client can leave instead of accepting. Finally, state when and how refunds are paid.
Ask the solicitor whether any of these need specific wording for consumers where you work. Renewal and payment terms are among the areas where consumer rules in many places add requirements about how clearly the terms are shown, and a draft written by a model working from general documents will not know which apply.
Records, progress photos and measurements
Training generates data beyond the PAR-Q+: body measurements, weights, progress photos, session notes. Some of it is health-related and all of it is personal. The contract should say what you keep, why, who sees it and for how long, and it should treat progress photos as a separate, optional consent, not a condition of training. Using a client's results in your marketing is a further step that needs its own permission. When you use AI to help with programmes or progress summaries, strip names and identifying details first, and keep photos out of consumer AI tools. State a deletion rule for when the arrangement ends, and agree the period with your solicitor, since it can depend on your insurer's and local requirements.
When the client is not the typical adult at a gym
One template rarely fits every client. The example trainer sells to four kinds, and each changes something:
| Client | What changes | Who to ask |
|---|---|---|
| Under 18, or under the local age of adulthood | A parent or guardian signs the agreement and the PAR-Q+, pays, and may need to be present; extra safeguarding care | Solicitor |
| Trains at home | The client provides a safe space and equipment; you may stop if it is unsafe; pets and children in the room | Broker, solicitor |
| Staff sessions paid by a company | The company is the customer on invoice terms; the client's health information must not go back to the employer | Solicitor |
| Online coaching | No hands-on supervision; the client's own equipment and space; recordings of sessions | Broker, solicitor |
It is usually cleaner to keep one core agreement and add short schedules for each case than to maintain four documents that drift apart. AI is useful at producing the schedules once the core is settled, and at checking that they do not contradict it.
Three client stories to test the draft
The quickest way to find a bad clause is to run real situations through it. Try these three on the example contract:
- The sprained ankle. A client rolls an ankle at home on Sunday and cancels Monday's 7am session at 6.30. The first draft says all cancellations under 24 hours are charged, so the client is billed for being injured. The fix is an exception for illness and injury with prompt notice, plus the pause rule that extends pack expiry.
- The serial late-canceller. A client cancels late three times in four weeks. The draft is silent on repeats. Decide what happens: a reminder, then a card on file, then prepayment. The solicitor checks that whatever you choose is clear in advance.
- The client who moves away. After four sessions of a ten-pack the client relocates. Under the draft's refund rule the answer should take ten seconds: $0, $360 or $300. If it takes a long email, the rule is not clear enough.
A one-minute summary clients will actually read
Few clients read a two-page agreement closely, and AI can help with that: once the contract is final, ask it for a plain-language summary box and compare every number against the contract line by line. An illustrative version:
Your agreement at a glance. Cancel at least 24 hours before a session and nothing is lost. Cancel later and the session is used up, unless you are ill or injured and tell me as soon as you can. Packs are ten sessions, valid for 12 weeks; if you pause for illness or injury, the expiry moves by the length of the pause, up to eight weeks. Complete the PAR-Q+ before we start and tell me promptly if your health changes. On a monthly plan, give four weeks' notice to stop. For a pack, see the refund rule on page 2.
Show the summary to the first three clients and ask them to tell you back what the cancellation rule is. If they get it wrong, the wording is the problem, not the client. Ask your solicitor how the summary relates to the contract, so the two never conflict and the summary does not promise more than the contract allows.
The pack to hand your solicitor
A solicitor works fastest from a short brief. Send the draft with the markers resolved, your price list, the insurance answers and a table like this one, which also shows where AI usually goes wrong:
| Clause | What AI usually writes | Question to put |
|---|---|---|
| Cancellation | Full charge under 24 hours, no exceptions | Is the charge fair for a reserved slot, and do consumers have a right to cancel I must mention? |
| Packs and expiry | Non-refundable, short expiry | Is the refund and expiry rule fair and clear at purchase? |
| Health | "Client is in good health" | Does the PAR-Q+ wording work with the contract and with minors? |
| Injury and liability | No liability however caused | What limit, if any, is allowed where I work? |
| Payment | Automatic charges with vague consent | Is consent to recurring payments clear enough? |
| Ending | Silent on renewals and records | What must the contract say about renewal and data? |
Once the solicitor has signed it off, put a version number and date in the footer and note in each client's record which version they accepted. Packs outlive policy changes: if you move from Rule A to Rule B halfway through the year, a client who bought a pack before the switch should still be dealt with under the terms they agreed, and the version note tells you which those were.
Questions trainers ask about their client agreement
Do online coaching and group sessions need a different contract?
Often they need extra clauses at least. Online coaching means no hands-on supervision and the client's own equipment and space. Group sessions add numbers, mixed ability and shared equipment. Tell your insurer when you add either service, and ask your solicitor whether to use separate versions.
Does the client have to sign on paper?
Not necessarily. In many places an electronic signature or a clear online acceptance is valid for an ordinary service contract, but you need a record of who accepted which version and when. Ask your solicitor whether e-signing is fine for your clients, including parents signing for under-18s, and keep every signed copy with its version number.
Can I charge clients' cards automatically for late cancellations?
Only if the client has agreed to it clearly in advance and your payment provider's terms allow it. Put the charge, the trigger and the way you will tell the client in the contract. Ask your solicitor about the rules for recurring and automatic card payments before switching it on.
If I rent space in a gym, do I still need my own contract?
Yes. The gym's terms govern your use of its floor, not your promises to clients. Check what the gym requires of you, such as insurance, and who is responsible for equipment, then keep your own client agreement and tell your insurer where you train.
