What is Crossfit?

CrossFit is the principal strength and conditioning program for many police academies and tactical operations teams, military special operations units, champion martial artists, and hundreds of other elite and professional athletes worldwide.

Our program delivers a fitness that is, by design, broad, general, and inclusive. Our specialty is not specializing. Combat, survival, many sports, and life reward this kind of fitness and, on average, punish the specialist.

The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.

The needs of Olympic athletes and our grandparents differ by degree not kind. Our terrorist hunters, skiers, mountain bike riders and housewives have found their best fitness from the same regimen.

Get Started

Getting started with CrossFit is simple at CrossFit Diem!

The first step is to set up your introductory Free Trial. This allows you the opportunity to meet us, see the gym, and find out first-hand, what we do and who we are. And of course, try a workout! If you, and we, decide that CrossFit Diem is for you, then your next step is to enroll in our Foundations On-Ramp.

Our On-Ramp Foundations course is a week long program that not only tests out your current fitness level, but also introduces you to the fundamental aspects of CrossFit. 

On-Ramp Foundations, is an elements type course consisting of the most foundational movements that will be encountered in a regular CrossFit class. This course is a requirement prior to being allowed into any CrossFit Diem class. You will be carefully exposed to each movement and taught the correct mechanics and range of motion needed to safely perform them. These movements are the core of the program and important in helping you achieve rapid and exciting success. They will be strategically spread out over a 6 day period and will range from easier/simpler to harder and more complex.

You will come to appreciate this course and the instruction that comes along with it. Each course only allows a limited number of participants. It’s going to be fun! 

We welcome you to make an appointment with us so that you may come in and see first-hand who we are, and what we do!
