Why Principia?

We’re not just another CrossFit gym.  At Principia, we are revolutionizing the way the Treasure Valley pursues health and fitness.

Our number one priority is to help you live your best life by constantly improving your fitness, your nutrition, and your mindset.⁠  When you start with us, you won’t just be thrown into the classes or into a group on-ramp program. You will receive one-on-one, individualized training specific to your body and your health.  We believe anything less is irresponsible.  

We have set out to be the most effective place to go to achieve results.  We do this through our Win It Back Process, a three tiered system of awareness, action, and automation that will demystify your path to your goals.

When you first meet with one of our coaches, they will perform an in-depth assessment of your fitness, giving you powerful insight into your body.  Armed with this information and your goals, we will create a systemized approach to get you from where you are to where you want to be, so you never have to second guess yourself again.

Clarify the process.  Systemize the approach. Finally feel confident, empowered, and in control of your future.
