“This gym has become part of my lifestyle. I'm able to hit the 30 minute workouts on my way home from work without feeling like I'm taking too much time away from my family.
The workouts are a constantly changing mix of heavy bag kickboxing and weights (never boring or predictable). It's a great way to clear your head and take out some post work aggression.
I highly recommend Circuit Three to anyone looking for a gym where you can crank out an intense workout and move on with your day. You'll find all skill levels there and no judgement.”

“As a veteran who has had to stop going due to service-connected disabilities, I can still say without a doubt that Arsenal is one of the best facilities I’ve ever been a member of. I particularly loved using their boxing classes—it was incredible for my memory, which is one of my disabilities. My speech therapist even noticed a significant improvement, which speaks volumes about the quality of the instruction and the workout.”

“Crossfit Eminence provides workouts for athletes of all levels. Chad, the coaches, and members make me feel like I belong there. They are friendly and very welcoming. It is a perfect space with plenty of equipment and 2 huge garage doors that get opened on nice days! I feel supported and encouraged to give it my all at each class. It’s in a great location with ample parking in the front and back.”
“Thanks to all the great coaches and staff at the Highlands location - you made my last 5 months of working out such a pleasure! In particular, Caroline patiently set me up, kindly tweaked my form, and inspired me to keep coming back for more! I’ll miss this location for sure.”

“I had initially bought a 10 class pack for the hubby as a gift and he convinced me to take a class with him once a week. Well, now I'm hooked and take multiple classes a week, with or without him. All of the coaches are amazing humans and my fellow FLY'ers are always so kind and supportive. It truly has become one of my favorite Denver communities. Even my 6-yr-old has caught the FLY bug and takes the Tuesday kid class. He LOVES coach Jamaica and coach Dillon!”

“I recently relocated to Erie and was eager to connect with like-minded individuals. Upon discovering CrossFit Erie, I was immediately impressed by its proximity to my new home. After my first visit, I knew this was the gym for me and the community I wanted to be a part of. Four months into my membership, I can confidently say that my experience has been exceptional. The coaches are not only highly knowledgeable but also approachable and supportive. The members are equally encouraging, fostering a consistent and motivating atmosphere. It truly feels like one big fitness family. I’m excited to continue my fitness journey here, with aspirations to participate in ultra marathons in the future.”
“Been coming here for a year now, can’t recommend it enough. A workout that really pushes you and a staff that motivates you to get through each and every session giving it your all. Everyone really cares for everyone, great sense of community! Facilities are kept impeccably clean, locker room has three showers on the women’s side with soap, shampoo and conditioner if your headed someone directly after a session too.”
