Powerhouse Gym Thornton is a veteran-owned gym offering a tight-knit community atmosphere with a focus on lifting and fitness goals. Located at 4251 E 104th Ave, Thornton, CO, it is well-known for its supportive staff led by the involved co-owners Jeff and Jacqueline. Members appreciate the knowledgeable trainers and quality equipment, alongside 24/7 access, ensuring flexible workout schedules. Despite its smaller size, the gym provides a wide variety of fitness equipment and a respectful environment where the gym etiquette is generally upheld.

However, the gym’s restrictive cancellation policies and occasional customer service issues have led to some negative experiences.

Honestly one of my favorite gyms I've worked out at in Colorado. Staff is awesome, great equipment and something about this gym gets me focused and in the zone. I've made more gains here than anywhere else.

Great gym, clean lots of equipment. Made me feel like a customer not just a number. Actually met the owners and everything super cool and down to earth. I always feel welcome. If I could give me stars I would.

Go here! This place is great for individuals at ALL fitness levels. Jeff the owner greeted me at the door was inviting and kind. He and his wife run this gym and you can tell it's not a corporate conglomerate wanting to force you into a contract you can not get out; Or who are pushy and start to act funny at the sign of customer reluctance EH EHM! L.A. FITNESS) They offer freezing your account because they understand life happens.Jeff took time to show me around and demonstrated top level customer service communicating the aspects of the gym and other perks; such as 24/7 availability to workout. Steve is a friend of the owner and assist in the day to day elements and it shows. Great customer service and you could tell pretty cool to be around. I felt bad I could not sign up today but I WILL BE returning.The gym is exceptionally clean and WELL maintained, not like those days of old were there is chalk all over and individuals yelling because the weight is too heavy. I HIGHLY recommend this gym for vacationers who visit Colorado's gorgeous landscape and I'm sure (don't assume he will I just think he is that type of personal find every way to accommodate costumes) Jeff will comodate you economically and set you up with a pass for the time you're here Supplying your fitness needs.Others, those who "eat the gym" this is your spot.

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 more than five 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. I recommend finding a different gym.

Great locally owned gym. Big free weights area and plenty of machines for isolation workouts. 2 Squat racks + a separate deadlifting platform. Everybody respects the equipment and re-racks their weights. Usually go around lunch and never too busy. Never have to wait for equipment either. Fantastic gym

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 love this gym ! The Owners/staff are AMAZING! Ive had membership in other big businesses as 24hour fitness/Vasa and felt like they did not care about my health but only for my money .Power house makes me feel very welcome the minute I step in the building . Everyone including the owners always motivate you, help you out on each individual way. I highly recommend this gym especially , if you are a Beginner like me . Where I had no idea where to start or how to use the Machines.Best choice I had made !

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.

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!!

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 glove inspection by how well it is maintained. If you are looking for a personal trainer talk to one of the Triple J's (Jeff, Jacqueline & Jessica). They seriously care about their clients achieving their fitness goals and the Triple J's are incredible people to be around. Jeff has been training me for almost three months and I'm loving the results of my body!I feel so healthy and happy! Thank you Jeff! If you follow the rules, pay your dues, be respectful and clean up after yourself; you will have a good time here. You should get a tour of Powerhouse to see what this place is truly about.
