I have been going to this gym for two years and love it so much. I used to be a long distance runner and was introduced to crossfit when I was rehabbing a knee injury. I never returned to long distance running and instead focused my goals on getting stronger. I never would have gotten there without the amazing coaches at CFS. They are so knowledgeable about the skills of crossfit and mechanics of the body. They do a great job explaining our warm ups and how they will help with our strength session and metcon. I love the programming and have really come to love lifting. My husband and I have made so many friends here and have enjoyed competing alongside them. I would recommend this gym to anyone in the Stapleton/Denver area.
