Fantastic gym! Great welcoming environment and encouraging staff. The other members make me feel like I belong. I really appreciate that they help me to ensure I am doing things with the proper form to stay healthy. Ive been going here for two years now and see no end in sight.

Been a member for over 5 years. Cant imagine a better gym and better people to work out with! John and Jenny are supportive and will push you to your limit as well. Its more than a gym its a community! Love it!

We have some of the greatest members! It fills me up to help and watch others achieve their goals. Watching people do things they never thought they could is an amazing feeling. The community of families who gather here are salt of the earth. Not only do I love my workouts, but the conversation we have before and after class Make this so much more than a gym!

After 5 months in and initial apprehension, I am glad I chose this gym to help me get in shape. John, Jenny and the rest of the staff do an exceptional job of making you feel welcome and do their best to make sure you are performing Crossfit work outs properly. In less than 6 months, I have lost close to 20 lbs and feel better and better with every work out. Not only do they push you to do your best but it also shows in their facility as they are continually upgrading and improving the environment.

Excellent crossfit classes for all levels. Coaches are awesome Jenny and Tyler so helpful. The workout will kick your butt, but the results are worth it.

I credit John and Jenny with helping me increase my flexibility, strength and overall knowledge of well-being (nutrition). They and their whole staff are committed to helping me get the most out of every minute spent in the gym. Rocky Mountain is located in a little building in Castle Rock that produces outsized amazing results for all that enter!

Awesome gym, great people and wonderful coaches. Everyone is very encouraging and supportive. Coaches really do coach and help you improve.

Excellent gym with knowledgeable and friendly trainers who truly care about your health and personal goals. Great family friendly atmosphere. Crossfit Kids is an awesome program if you want to get your kids active and moving! Excellent staff, excellent classes, highly motivating and highly recommended!!!

My daughter is attending Rocky Mountain self-defense twice a week for CrossFit and Krav Maga back to back. I love how the stuff make it so much fun for kids to learn good habits, discipline, respect, self-awareness and confidence starting at such a young age. The kids are definitely gaining a healthy fit lifestyle.

Motivating atmosphere, encouraging without being super competitive. Owners teach most of the classes. Highly recommended

Wonderful community! The coaches are all very knowledgeable in their field and work great with every skill level. They have classes that fit into everyones schedule. I am a huge fan of their 6:00am Crossfit class :)

RMSDF has such friendly, knowledgable, and motivating coaches. Ive been coming here for years, and consider the people here family. I recommend this gym to everyone I know, Its the best place to work out!

Cross fit wasnt something that I thought I would enjoy, but after meeting Jenny and her staff I quickly changed my mind. I look forward to every workout, feel great after, and feel terrible when I miss a workout. Even if you are an absolute beginner, the workouts are customizable to make sure that you feel comfortable and get a great workout!

Mountain CrossFit rocks! I have been a student for close to ten years with John Hallett. He and Jenny are patient and encouraging. The school has a very fun and engaging atmosphere!

I highly recommend Mountain Crossfit. Extremely family friendly atmosphere and motivating members. Ive been going to Mountain Crossfit for several years and highly recommend the gym to everyone.

John & Jenny run a fantastic crossfit program. It is both enjoyable and challenging. They and everyone who trains is always encouraging and supportive. I started crossfit to improve my Krav training, and also found a program that is fun, makes me sweat, and a place with great folks with whom I get to train. 5/5 every day! Come on down & work out with us!

Phenomenal environment and people. Supportive, encouraging for every size, age and goal!

Member for over 5 years and counting! I started at age 46 and realized that Crossfit is for EVERYONE! You wont find a better coaching staff in Castle Rock. Highly recommend.

Very supportive staff. I wasnt sure I could handle crossfit but with the support and guidance of the staff I can and do.
