"I love the atmosphere of CrossFit Thornton. The friendly vibe and supportiveness of all the members keep me coming back. That and the coaching – I’ve never had this kind of attention to detail without having to pay for a personal trainer!"− Sarah
"I’ve been a member at this gym for about 3 weeks. When I walked in the door for the first time I didn’t know how to do any of the lifts. The coaches are very knowledgable and eager to help. They go over every single exercise that we will need to know for the warmup and for the actual workout. They are very attentive. They are constantly coaching, giving motivation and tips on technique during the workouts. I’m not an athlete and I’m also a little shy. When I went to my first workout the other members introduced themselves to me right away. It made me feel very comfortable. Everyone supports each other during the workout. Members want to see each other do well. It’s a great gym."− Lexington

History of CrossFit
CrossFit was formally established in 2000 by Greg Glassman. By 2005 there were 13 affiliate gyms. Because of the incredible results people have seen, there are now over 8,800 CrossFit affiliate gyms worldwide, making it the largest fitness organization in the world. How do you argue with those results? One of the best articles, published by “The Box” magazine, outlines the history of CrossFit. One of CrossFit’s largest strengths is that it is scalable and usable by anyone at any age. There are 80 year old people using CrossFit to stay healthy, 350lb + people using CrossFit to lose weight, and 5 year old children using it to learn about fitness. Even the US Military uses the methodology to train it’s Special Forces.
A simple way to sum it up. CrossFit founder Greg Glassman realized that specializing in one athletic domain meant losing the ability of the athlete to perform in others. Think of the strength capacity of a marathon runner, or the endurance capacity of a power lifter? They gave up one capacity for another. Greg’s goal was to determine the “Best methodology to determine and produce the fittest humans on the plant”. His discovery was that by mixing the best training disciplines of other sports, we could become the best and most fit versions of ourselves. What is athleticism? It is being able to perform optimally in the following modal domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance and accuracy.
CrossFit is the most effective way to do this, in the least amount of time. 8,800 gyms and hundreds of thousands of people can’t be wrong. If you’re in or near Thornton or Northglenn and surrounding areas, come join a CrossFit Gym who values you as an individual and wants to help you achieve your goals.
