I'm Dean, a REPs certified personal trainer based in East London. I built this because my clients kept asking the same questions — how many calories should I eat, what's my protein target, how fast should I run? I got tired of sending them to clunky apps that require sign-ups and show ads. So I built a clean, free hub that gives instant answers. No email required, no app to download, works on any device.
