Who We Are and Why We're Building This

We're Philip and Nick, an ex European champion 🏸 turned entrepreneur and a nerdy bodybuilder 🏋️ who builds tech products. We came together to create the best personal trainer on earth and make it accessible to everyone.

Our mission is to democratize fitness technology: take all the expensive, gatekept tech and techniques that pro athletes use and give them to everybody. We use the latest in science-backed fitness research and experience of global thought leaders to make getting fit a sure thing.

Our goal at Calibrex is to use the latest technologies to do everything a world-class personal trainer can do but better, cheaper, and faster making your journey to your fitness goals as easy as it can be.
