CrossFit is a fitness program with the aim of building a broad, general, and inclusive fitness.  Basically, we want to become ready for anything life throws at us.  We do that by performing Constantly-Varied Functional Movements at High Intensity.  I know that was a mouthful, so let's break it down piece by piece. 

Functional movements are our body's primary movement patterns.  Think squats, push-ups, pull-ups, deadlifts, presses, rows, lunges, and weighted carries.  They engage multiple muscle groups across multiple joints and give us the most bang for our buck.  So they make up the majority of our program. 

Next, we have the constantly varied aspect of CrossFit.  This is where we differ from a lot of other programs because no two weeks of our workouts look the same.  We're constantly changing up the movements that we do, the rep schemes, and how long the workouts last.  Not only does this break up the monotony of going to the gym, but it supports our overall goal of being ready for anything life throws at you.  

Finally, we'll discuss the high-intensity component of CrossFit, which is relative to the person.  Everyone who enters the gym does so with a different training history, injury history, age, gender, etc.  So, it's our job to provide you with a workout that is not too much, not too little, but just right for your current abilities.  You will never be thrown into anything you can't handle.  The workout will always be modified to meet you where you're at and progress you from there.
