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. While the facility is praised for its cleanliness, the cancellation process requiring in-person attendance and delayed responses have been frustrating for some members. It's a suitable choice for those looking for a locally-owned, supportive gym environment, but potential members should be aware of the cancellation terms.

  • Supportive and approachable staff
  • Knowledgeable trainers available
  • Quality and varied fitness equipment

Husband and I have been attending this gym for about 2 years now. Love that we can get access, even if the staff isn’t there. There are plenty of cardio machines, free weights are usually taken up/pretty busy during the week after work. It’s always clean, and so are the bathrooms. They started offering child care for those people who have kids. They do seem to shut down some main lights, TVs, and music after 8pm. Music isn’t such a big deal since most people wear their headphones. Parking lot is on the smaller side and no lines for the spots.

Great gym. Staff is cool as hell, the owners are very knowledgeable about everything from what exercise to do and how to do the exercise all the way to how to shape up your diet. The members are all super friendly and respectful. I have never had an issue getting a certain machine or spot in the gym, even at peak times after work. You can always find a piece of equipment because the members actually put them back where they belong (Unlike members at VASA and Chuze.) If you're looking for a gym with a very friendly atmosphere and not a corporate atmosphere, I would come here.

This place is awesome. Not only is it 24 hour access but its always clean. Never have trouble using the equipment, even during peak hours. Members are friendly and willing to share. Feels like a community. They added some new equipment thats helped really key in my workouts. Most importantly, they have the best staff out there. Ive been to all the big box gyms and an MMA gym and this is as close to family as it gets. No matter what time I go I feel I belong there and so does my wife and our child. They have a child care for when you're working out, which our daughter loves. They're great with her and she actually asks if we can go all the time. We couldn't ask for any better from a gym. Ive noticed they have a sense of community and bring people together and encourage and inspire

Great gym, great staff! This gym has everything you need to achieve your fitness goals. This gym has a great culture and everyone there is very respectful and friendly. I’ve never had to wait to use equipment and always get in a great workout! Shout out to everyone at this gym for creating such a great environment.

Power House Update - This place has truly gone down hill. I am at a loss for words as they still have not replaced their broken down equipment. Last week my daughter was running on a treadmill that shut down on her during her run. This is dangerous and somebody is going to get hurt on this equipment. I have had the same issue with various treadmills and the owner, Jeff, told me I could run out doors. I pay for a gym membership for a reason and expect to have safe equipment to work out on.

This place is absolutely Amazing! The new owner really seems to care about his employees and more importantly the club memebers. Its rare to see an owner to take such passion and pride within his community, no wonder he tosses "the trash" when the standards are not being met. I look forward to seeing the new changes and the clean up he puts forth. More importantly, I'm glad to have a place where I can train and feel welcomed without having pressure to buy and order unneeded assistance. This place actually cares about the overall well being and safety of each memeber. No jerks are welcomed their.

It's so good to finally be leaving this gym in my rearview. I was a member here for 3 years, 6 months and I can tell you the majority of these positive reviews are from current and former employee's aswell as their family and friends. That's the equivalence of using your mother as a work reference, ofcourse she's going to say you're the best. I stayed as long as I did because my workout partners didn't want to leave but now they've decided to venture off to new gyms and so that's my cue to leave.I've seen this gym struggling for awhile and don't see it lasting much longer. The only reason this gym was successful was because of it's location and lack of competition but that all changed last year when chuze fitness, Planet Fitness and youfit opened up in the area. Even the old Kmart is being turned into a Vasa Fitness and will be opening this summer. There's a reason the old owner Sarah recently sold the gym. This new owner has no idea what he is doing, he bought a lemon and is only chasing away longterm members with his changes.What I hated most about this gym was the atmosphere. Lot's of Drama spearheaded by the staff. People only coming here to find a boyfriend/girlfriend. Individuals more interested in making friends and small talk. Lots of Gossip and trash talking of members. I experienced more drama here than I did in college and I was in a fraternity. I was labeled an a**hole because I kept to myself, didn't participate in small talk and only socialized with select individuals who I worked out with.The only employee's who were worth their weight in gold was Chris Maese, who doesn't work here anymore and Patrick Duffy.

This gym is way undersized and some of the male staff harasses female members. If your looking to make gains this gym is not the place. If your looking for a social hour then this is your home. Equipment is not maintained and very little lifting equipment compared to cardio. There are also no amenities with this facility. Chooze fitness is cheaper and cleaner with more amenities,
