“The community that Mountain Strong has been able to cultivate is wonderful. With many conditioning gyms, it sometimes can feel intimidating but not here. The coaches and owners make you feel part of their family. The members are open, friendly, and the best part, encouraging. The environment here allows your training to feel fun, that's the sweet spot in my opinion. Moving to Colorado and now been here for 2 years, 90% of my friends are from here. The gym always has phenomenal clinics to work on all types of things. From breathing, to climbing knots, to getting your rowing form perfect. They're always getting the community together for fun workouts followed by a relaxing BBQ after. I can write on and one but this place is truly magical. I am so grateful for the connections and life long friends that I have made. This has everything to do with the coaches and owners who have dedicated themselves to creating a place where your health and training can be a happy adventure. Don't get it twisted, they bring it and you will get your pump on but in a fun way.”
“This place is HUGE! It's clean and well maintained. The coaches are second to none and there to help. Gabe is great, so if you're looking for a gym that will get you to that next level whether you're a beginner, intermediate or a pro this place is for you! Thanks CrissFit MOB!”

“After 2.5 months coming to CrossFit ELM, I can safely say that I love this place!! I’ve never been one to work out consistently, but this incredibly run community that these thoughtful coaches have built is a safe haven. I cannot recommend them enough! Everyone that coaches and trains here is cheering you on, there’s zero judgement and it’s always super fun. Thank you CrossFit ELM for pushing me to reach my fitness/health goals and skillfully teaching me every step of the way.”
“My son has extreme ADHD and we where looking for an energy release for our child weekly. The instructors there have been very patient and do their best to keep his attention and my son loves this place”
“My 16 yr old and 10 yr old boys have been going here for a while now. Amazing gym for kids to learn. This is truly a great place for kids to develop athletically.”
“I have been to a few Orangetheory studios and there has yet to be another studio that compares to the Thornton studio. The staff and coaches have built a friendly and accepting atmosphere with a community that supports and cheers each other on. The excitement and passion the members have when they show up to class is unmatched to any other studio I have ever been to. I would highly recommend this gym if you are looking for a supportive community to achieve your health goals with a staff that motivates and pushes you.”

“A friend invited me to Jazzercise-Thornton, and I couldn't be happier that she did! As someone who has had anxiety about stepping into an exercise class, this place has been an incredible find. From the moment I walked in, I felt a sense of support, motivation, and most importantly, fun.Being a new member at Jazzercise-Thornton, I am beyond thrilled to be part of such a welcoming group. The instructors and fellow participants have made me feel right at home, and I can't wait to continue my fitness journey with them.If you're looking for a place that not only offers a great workout but also creates an inclusive and uplifting environment, Jazzercise-Thornton is the perfect fit. I highly recommend joining this amazing community!”
“Probably the most well equipped PF I’ve ever visited. The first I’ve seen with a dedicated TRX station. Nice. Loses one start though because unlike literally every other PF this place doesn’t have the lockers with built in locks.”
“It’s so nice finding your people when you’re traveling to other cities. This gym has everything you need and the staff are so cool. I know where I’m training when I’m back in Denver.”

“Even though the gym can be packed at times this is an excellent facility. The reasons why: Staff is very helpful and down to earth, the gym is super clean. The people there are very respectful. Facilities stay open and actually work. The air is super clean. There no weirdos in there recording. I like it.”

“It's a pretty good gym. You get what you need out of it and I haven't had any bad experiences there. It's a mix of people as far as the type of gym experienced go. Both ur meat heads and ur newbies go there but neither seem to be over the top. The one positive I will give that that stands out from other gyms is that they have an outdoor area to work out in. A lot (if not all) of gyms don't have that. And that's nice especially when it's not cold out outside. Flip some tire. Oh and values is great, $10 for the basic plan to just work out. $25 to do all the other stuff I don't do like message lounge, tanning, pool, sauna, etc. ”

“I was a member for many years. We recently moved out of the area, and I have to say how much I miss Adventure!! Such a great environment to work out in! Susan and Mike are top notch, and they take great care of the gym. More equipment than you can imagine! This isn't just a place to work out, it's a community. I've done many of the classes over the years and Dave Mura's 5 am class is the best!! It's a great mix of HIIT, weight training, tabata and fun! Definitely try this gym!!”
