Owner Chuck Rumbley opened Crossfit Calidus in April of 2013. It was only natural for the manufacturer of the best bumper plate in the world to open a Crossfit gym where they are used the most. The gym name is HI-TEMP Athletics but the affiliate name is Crossfit Calidus which in Latin is an adjective that means heat or having passion. This describes the way we train and coach 100%. We are passionate about how we train our clients and how they train.
