Called around to different gyms looking for something different. Power House has become my home for training. Members at the gym go to work out, not on their phones. Serious clients and serious staff. Highly recommended.

Do not sign a contract with these people. They told me there’d be no cancellation fee if I moved & when I did, they refused to even allow me to cancel the contract without coming in. Then when I did, they said I could just email them. They want $200 to cancel a contract they verbally attempt to change every time I get ahold of them. And for what it’s worth, the gym is decent at a decent price. You might as well get something better or go to Anytime Fitness.

Great gym for elite powerlifters and casual lifters alike. They have all the equipment I could ever need and it's laid out nicely. There's even an area where you could push a sled, do plyometrics, wind sprints or whatever it is you wanna do. Would highly recommend!

This gym is top tier!!! The gym is always sanitized, and perhaps even that word is underselling it; it is immaculate. You'll be able to tell from the moment you walk in that the staff really cares about everyone and invests into them. There is a great vibe inside and everyone that goes there is respectable and upbeat. Love this place!!

Came in because it was close to our hotel. One day pass is $15 and that’s a little expensive, however, the people are nice, the gym hasn’t been filled to capacity the couple times I’ve been in, and it’s a nice clean place. If I lived in Denver, I’d go here. Customer service goes above and beyond, they genuinely seem to care about you. Highly recommend.

I love supporting a small Veteran owned business and getting away from big box gyms. Powerhouse is the kind of gym I grew up lifting in. The people and atmosphere is the best part of it. Always approve encouragement from others. I def recommend giving this gym your money and time.

I Signed up recently and went through a bump in the road with my membership for another person on the account within a week of signing up for the membership. The owners Jeff and his Wife Jacqueline assisted me through other options to help me out with the membership and in the same token to give this gym the business signing up my nephew. On the upscale of keeping this gym clean, they clean this gym daily and make sure all the machines and gym floors are up to par on cleanliness. The whole Staff is legit and are straight fwd. Jeff, Jacqueline, Steve, Jessica, and Natasha are straight up with everyone

I had been a member of a variety of gyms in Colorado and California throughout my life. Powerhouse Gym is bar none the best gym ever! It doesn't matter what shape, size or fitness level that you come in; Powerhouse is for you! No joke this gym is open 24/7 and have the gym equipment you need. The Powerhouse employees and owners are amazing folks who are very knowledgeable, helpful and passionate in what they do which makes Powerhouse so great. When the staff and owners are not busy helping out their members. They are cleaning up and keeping the gym organized. This place could easily pass a white

Powerhouse has become my other church. Solid bunch of people, Veteran owned and operated. Friendly staff, great equipment, the kind of gym I grew up in lifting as a kid.

I am posting this on behalf of my husband:
The gym is great; but when you try to cancel a membership, they give you the run around. I moved earlier this year and requested that my membership be cancelled. I asked that this be done in May and I’m still being charged (six months later). I emailed the manager numerous times and called, all to no… avail. In addition, if you’re a military member, they claim you can cancel without a fee—this was not my experience. The only way I was able to cancel was through my bank. Be very careful when signing a contract with this business

Working with one of the personal trainers on site- Jeff, has been two words: Life Changing. I have always been an active person and have recently been trying to take my fitness to the next level... this was the way to go. From being so knowledgeable not only with the right techniques and excercises, but also we have been killing it on the nutrition side too. If you don't need a personal trainer and just looking for a great, affordable place that is extremely clean, with an incredible staff... this is the place for you!
