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.

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.

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.

Do not sign a contract with them or you will end up in collections. I contacted them multiple times over phone and e-mail could never get a response of my actual payoff amount to cancel the membership, months later a collection agency reaches out. I ended up with late fees and months of not knowing I was getting charged. After asking multiple times they will just quit responding. It seems they handle things very unprofessionally here and from looking at others comments they have had the same issue. Every gym in the Denver metro area is a better choice in my opinion. Only perk to this gym is being open 24/7 and that’s all they have going for them. Not sure it will be open much longer being ran this way!

I was actually going to check this gym out as I have loved Powerhouse gyms in the past. However, after reading the owners responses to the reviews on cancelations. I’ve decided to look elsewhere. I don’t want to pay for a place that condescends its guests when all of the lower rated reviews seemingly have the same issue with the cancellation policy. I would think a saavy business owner would express clearly the policies and reiterate them if everyone seems to have the same issue.

Went here a few times with my partner and had negative experiences each time. The one positive was being greeted by Natasha when she worked there. There are way to many machines for cardio and the layout of equipment doesn't flow well. The regulars/members do not practice proper gym nor lifting etiquette -- guys tend to walk in front of you when using the mirror, no common courtesy from members nor owners about posting gym etiquette. Being the son of a bodybuilder, I know that following proper procedure and form in the gym is more important than lifting weights. Additionally, I never saw the owners in the space and I went during normal business hours (9am-5pm, M-F) so that was concerning as a fellow small business owner.Also reading the other review replies from the owner - -wow, he has time to be a pompous gym owner and act like he owns the world with money, yet can't address the ISSUES that are extant? If numerous individuals express issues with your contract, then you need to revise and edit that dude. Who cares that you're a "small business owner" - -fix your mistakes instead of being a child about them. Pushing the "responsibility" onto your customers is extremely corporate, not small business.

My Iron junkie gym. People come here to work and encourage and educate others on how to train. This is a tight community of good people who are all on their own journey and work hard to get good results. I proudly wear my PH Gym swag and love giving my money to a veteran operated local business.

Can’t recommend Powerhouse enough! The staff is so nice and always willing to answer any questions. I’m always greeted when I walk in and the owners not only keep the place super clean and well staffed but are always around. I’ve been to lots of gyms and most of the time you’re just another person but at Powerhouse you can really feel the support! I’ve seen so much improvement in my lift it’s crazy and I owe it all to Powerhouse.

I love Powerhouse! I've been a member over 2 years now and it's the longest I've been with a gym consistently. It's never too busy, veteran owned, has quality supplements, and everyone is so nice and respectful of equipment. I've learned how to correctly lift weights here thanks to the best trainer I've ever had (Jacqueline, co-owner). The owners are great people who care about and are always improving the gym and the manager Steve is not only badass but is willing to help with anything (I ask for form checks and how to use equipment all the time). I highly recommend anyone experienced to novice to join, it's a great community.
