We would love to hear from you. The best way to reach us is by email.

What to write to us about

Corrections. If you spot a factual error or an out-of-date figure, tell us the page and what you found. A link to your source helps a lot.
Feedback. Was something unclear? Is there a topic you would like us to cover for beginners?
Privacy requests. To ask for access to, or deletion of, anything you have sent us, email us and say so. See our privacy policy.

What we cannot do

We are not able to give personal training, nutrition or medical advice, to check your form from a description, or to comment on a health condition. For those, please speak to a doctor, a registered dietitian or a qualified coach. In an emergency, contact your local emergency number.

Please do not send us sensitive health information about yourself. We do not need it to answer a question about the site.

When to expect a reply

We read every message. We reply as soon as we can, usually within a few working days, although we cannot promise an answer to every message.
