Editorial standards
Every guide is written and checked by Chris against published evidence — peer-reviewed journals such as the Journal of the International Society of Sports Nutrition (JISSN) and Medicine & Science in Sports & Exercise (MSSE), alongside the NHS and the British Nutrition Foundation. Sources are named and linked so you can read them yourself.
Every calculator uses a published formula, and each one is checked with automated tests against worked examples before it goes live.
The Hub is edited by one person. It does not have clinical or medical review. Nothing here diagnoses, treats or manages a medical condition — for anything medical, speak to your doctor or a health professional.
From the Hub to the app
The Muscle & Strength Hub is the free publishing side: guides and calculators anyone can use. Bodywise Coach is the app built on the same evidence and the same calculations, for people who want a plan they can follow day to day.
- 11 free calculators on the Hub
- Open calculator endpoints that other developers and AI assistants can use
- A public connection point so AI assistants can run the calculators directly
