Welcome

Body.build is the world's most advanced weight lifting application for advanced lifters. The goal is to make something free and open to everyone, no strings attached; to achieve something like WikiPedia for weight lifting, but personalized and actionable.

I took the Menno Henselmans Personal Training Course - the most in-depth science-based personal trainer course in the world - and graduated Magna cum laude in 2025. Now I want to share this knowledge with everyone through an awesome, free tool.
