Liability Waivers for Personal Trainers: What to Include

Why Every PT Needs a Liability Waiver

Before your client completes their first squat, you should have a signed waiver in place. It sounds administrative, but it is one of the most important documents you will use as a personal trainer. A liability waiver does not eliminate risk — nothing does — but it sets clear expectations, demonstrates professionalism, and helps protect you if something goes wrong.

This guide covers what a solid waiver should include, written as guidance on using templates rather than legal advice. Always consult a qualified solicitor if you have specific legal questions about your situation.

The Core Elements of a Strong Waiver

A PT liability waiver needs to do several things at once: acknowledge that exercise carries inherent risk, confirm the client understands that risk, and record their voluntary agreement to proceed. Here are the sections you should not leave out.

Identification of the parties. Name yourself (or your business) and the client clearly. Vague language here creates confusion later.

Scope of services. Describe the training you are providing — one-to-one PT, small group sessions, outdoor training, online programming. If your scope changes, update the document.

Assumption of risk. The client should acknowledge in plain language that exercise involves physical risk, including the risk of injury, and that they are taking part voluntarily.

Health disclosure acknowledgement. A waiver should note that the client has completed a PAR-Q (Physical Activity Readiness Questionnaire) or equivalent health screen and disclosed any relevant conditions to you. This is not a replacement for a full medical screen — it simply documents the conversation.

Limitation of liability. This section sets out what you are not responsible for, within the limits the law allows. No template can override negligence, so keep your practice safe and your record-keeping thorough.

Medical Conditions and Special Populations

When you work with clients who have pre-existing health conditions, are pregnant, are elderly, or are under 18, your waiver needs to reflect that. These sessions carry additional considerations, and your documentation should show you have thought carefully about them.

For under-18s, a parent or guardian should countersign. For clients with medical conditions such as cardiovascular issues, diabetes, or musculoskeletal injuries, consider asking them to obtain GP clearance before starting — and document that you did.

REPs and CIMSPA member trainers are expected to follow professional practice standards around screening. Your waiver is part of that professional record.

What a Waiver Cannot Do

It is worth being direct here. A liability waiver does not protect you against negligence. If a client is injured because you instructed them incorrectly, pushed them beyond safe limits, or failed to spot a contraindication you should have caught, a waiver will not shield you. What it does is clarify the voluntary, informed nature of the client's participation — which matters in a genuine dispute.

This is why professional indemnity and public liability insurance is non-negotiable. Your waiver and your insurance work together; neither replaces the other.

Keeping Waivers Current

A waiver signed three years ago may not reflect your current services, your client's current health status, or any changes in your terms. It is good practice to have clients re-sign annually or when there is a significant change — new injury, pregnancy, major health event, or a shift to online or outdoor delivery.
