Informed Consent

Informed consent is a client's documented agreement to take part in a training program after being told what it involves and what the risks are. It records that the risks were explained and understood, and it is standard practice in fitness before any physical assessment or training begins.

It is a conversation, not a form

Consent is only informed if the client actually understood. A document signed without discussion, in language the client cannot parse, does not establish that. Walk through the main points in plain words, invite questions, and make it genuinely comfortable to say "I would rather not do that exercise".

That last part matters in practice as well as in principle. A client who believes they are allowed to refuse something will tell you when a movement hurts, and a client who does not will keep going and get injured.

When to refresh it

Consent is not a one-time formality signed at the start of a relationship that then covers everything forever. It should be revisited when what the client agreed to materially changes.

  • When the program changes significantly in type or intensity.
  • After an injury, an illness, a pregnancy or surgery.
  • When you introduce assessments or methods that were not in the original scope.
  • When you want to use their photos or results in a new way, which is a separate consent.
  • At regular intervals for long-term clients, alongside a health screening refresh.

Key takeaways

  1. Informed consent records that the client understood the activity and its risks before starting.
  2. It is not a waiver; a waiver limits liability and does not replace consent.
  3. It only counts if it was a conversation the client actually understood.
  4. Refresh it when the program, the client's health, or your intended use of their data changes.

Frequently asked questions

Is informed consent the same as a liability waiver?

No. Consent documents that the client understood the activity and its risks. A waiver attempts to limit your liability if something goes wrong, and how far it holds depends on local law and the circumstances. Many coaches hold both, and neither substitutes for the other.

Do I need informed consent for online coaching?

The professional argument is stronger, not weaker, because you are not there to intervene. You are prescribing training a client performs unsupervised, so what they were told about risk, and what they were asked to disclose about their health, matters more. Check your own insurer's requirements, since they often set the standard in practice.

How long should I keep signed consent forms?

Retention periods are set by local law, your professional body and your insurer, and they vary, so this is a question to put to a professional in your country rather than to a glossary. What is universal is that the documents must be stored securely, since they contain health data.
