BeginFit explains fitness for people who are just starting. This page explains how we write our guides and tools, how we check them, and what we will never do.

How we write

How we check facts

What we will never do

Our tools

Each tool explains how it works, what it assumes and where its answer may not fit you. We only list a tool as ready once it works and its maths has been checked.

Our app

We make the BeginFit app, and we sometimes mention it in our guides. When we do, it's because it is relevant, and we only describe features that exist today.

Not medical advice

Our guides and tools are general information, not medical advice. If you have a heart or lung condition, are pregnant, had recent surgery or have pain that worries you, talk to a doctor before you start or change your training.

Updates and corrections

We review our guides and update them when the evidence changes. When we fix a mistake, we update the date at the top of the page.
