Gym Number Five

Fantastic experience: go to for high school athletes .

Fantastic experience: Best gym in the Boulder/Denver area. 24hrs, great staff. Excellent for strongman, powerlifting and bodybuilding.

Fantastic experience: I've been training at this gym for just over three years. In that time the facility has continually improved and adapted to the changing needs of its members. The coaching staff is incredibly professional and knowledgeable, helping me to secure a national championship in my sport while improving my overall health and performance. I've been to just about every strongman gym in Colorado and Gym 5 is by far the nicest, with just about everything you'd ever need for comp prep.

Fantastic experience: Best gym in Boulder

Fantastic experience: Very nice gym. Been working out here for a few months. No complaints.

Fantastic experience: Best gym you’ll ever go to. Love it here. Can’t recommend it enough.

Fantastic experience: Wonderful gym: always clean, plenty of plates and racks to work with, and great selection of machines. Staff are very friendly and the general atmosphere is one that makes you feel comfortable. Enjoy training here!

Fantastic experience: I joined Gym Number Five this summer, and I have found it to be a fantastic gym for anyone interested in strength sports/strength training! They are extremely well-equipped -- I use equipment for powerlifting and olympic weightlifting, but there is also a ton for strongman and bodybuilding. I also find the staff to be very welcoming and helpful, and the overall atmosphere of the gym is awesome (which I think makes my workouts much more enjoyable). Definitely recommend checking out if you are in the area!

Fantastic experience: Been training here for years and they’re always tweaking the layout and adding equipment to respond to athlete’s needs — it’s a great vibe where it’s easy to train hard!

Negative experience: First of all, I'd like to say that Russ (the owner) is great. The community is great. The equipment is high quality, niche, and very well-maintained. That having been said, ever since Russ outsourced the billing to a 3rd party service, it has been a complete nightmare to deal with, insofar as I went to cancel my membership due to the issues. Russ used to have a very personal touch with members and operations, but I'm sad to report this is no longer the case. Case in point, I went to cancel my membership close to three months ago and they have made me jump through hoops to get it done. I'm used to this type of treatment from commercial gyms (as making it nigh on impossible to cancel membership is part and parcel of their business model), but expected better from a boutique gym like Gym No 5. I get that Russ is a busy guy and doing billing by hand for each member is no longer reasonable to expect given the stage of the business, but he needs to find a better vendor. Left with no further recourse, I had to begrudgingly initiate a fraudulent charge dispute with my bank in order to get any resolution. It's a damn shame that our relationship together is ending on this sour note after having been a happy member for many years, having spent many, many thousands of dollars for the privilege. Hope you see this Russ and make the necessary changes.

Fantastic experience: Fantastic gym with all the powerlifting equipment one could want. Trainers have tons of expertise and there's a wonderful community within the gym.

Positive experience: Its amazing! They have everything you need to get to where you want to be.

Negative experience: This gym has truly disappointed me in the way they have handled a cancellation of membership. My 15-year-old daughter was trying out gyms since CAC closed. Gym#5 told her that she could cancel her membership with 30 day notice. They won’t honor that promise and pass it on to an agency that handles their payments. I am a small business owner and I don’t understand this. Their responses sound pre-written in legalease, making me surmise it’s something that frequently comes up. We are pursuing our legal options, but more importantly, they should just be good people. Is this really how you treat people? After reading your response I can only say that it's such beautiful language for such an ugly way of dealing with your customer. I can assume that you're probably very financially stressed, but that shouldn't warrant your threats or tactics. And btw, I do hire professionals, but not the type you do. My daughter feels so guilty about believing Gabby when told she could cancel the contact with a month notice. My daughter went to gym for 3 days and we’re expected to pay nearly $800 to get out of the contract. What kind of business does this to a child?

Negative experience: Dudes watching each other lift things

Fantastic experience: I drove over 25 minutes each way for over 3 years to workout at this gym, because its amazing! They have everything you need to get to where you want to be.

Fantastic experience: Absolutely fantastic gym that is meticulously kept. Did 2 drop in passes which were seamless to set up. Gym size is great and the equipment is top notch. Barbells, power racks, cable machines, DBs were all some of the best i have used.

Fantastic experience: Great gym!

Fantastic experience: Not your average gym folks. Great equipment, friendly staff and a great workout!!

Fantastic experience: Hidden gem in Gunbarrel.

Fantastic experience: Dream gym. Has the nicest, most functional iterations of every piece of equipment most athletes could ever possibly want. The vibe is great - relaxed and communal, but serious athletes in there. Coach Russ is an absolutely pro, next-level coach. Truly knowledgeable and worth every dollar.

Fantastic experience: If you are a powerlifter or strength athlete in the Boulder/Longmont area, this is the place to be. It has everything a lifter needs. Competing in USAPL or Powerlifting America and need a competition stiff bar? They got it. Competing in a federation that allows specialty bars? Got them too. Or perhaps you are looking into the sport of strongman? They got nearly all the equipment for it, axles, logs, stones, yoke, you name it, they probably have it. The owners are always looking to make the gym better and bringing in new equipment regularly. The atmosphere is second to none, where you will feel like you’re at home. The people here are also great, very willing to help when you would need it, with the amount of knowledge combined through everyone, just about every question you have has an answer. Now with the owners bringing in new equipment, the machine areas are a little bit dense and cramped, there is more than plenty of space throughout the gym as a whole and it is probably the only real gripe I would have with a place like this. If you need a gym experience that has the desire to become better, faster, stronger, there is no better place to level the f__k up.

Fantastic experience: I have been training with Russell at Gym No. 5 for six months and have seen massive gains in my strength and performance. By following Russell's training program and macro splits, I put on 17 lbs of muscle in six months. He is the real deal.

Fantastic experience: Great gym. Very well equipped. Friendly staff.

Fantastic experience: Man, what an awesome place. Where I trained prior was about a fifth of the size and a fifth of the equipment. Everyone is very friendly and helpful. Highly recommend.

Fantastic experience: Gym 5 is the real deal. What an amazing facility with top of the line equipment. If you can get an open spot to join- take it!

Fantastic experience: If you are serious about Weightlifting, Powerlifting, Strongman, or even arm wrestling, no5 is the only gym in town.

Fantastic experience: I’ve been going to Gym Number Five since just after it opened. Over the years, I’ve worked out at gyms in different parts of the US and the world. In my opinion, Gym Number Five is easily the nicest of them.

Fantastic experience: Best gym in the area

Fantastic experience: This gym has everything you need and equipment you didn't know you needed. Open 24/7; perfect for the serious athlete and busy professional alike.

Fantastic experience: best gym in boulder

Fantastic experience: If you enjoy weightlifting, this gym is like if Amazon owned a gym. They GOT the equipment you need.

Fantastic experience: Had my first day of arm wrestling. What a wonderful and inclusive group of people.

Negative experience: Seems like they are hiding the membership costs a bit. I see $79/month for the basic and no other info... Id like to know the cost before doing the free trial, seems cool otherwise...

Fantastic experience: Great training environment. Everything a serious lifter needs lies within these walls. They even have bidets in the bathrooms!

Fantastic experience: Awesome gym. Easily has everything anyone would need!

Fantastic experience: Amazing gym!! I've been a member of several great gyms in the Mecha of bodybuilding and strength and performance training that is Columbus Ohio, but I can't compare any of it with the quality experience I had in my time at Gym No.5. From the high caliber equipment, to the environment, to the amazing and personable staff and ownership, this facility of fitness stands head and shoulders above the rest. I will greatly miss my time there. Leaving because I couldn't take full advantage of my dollar there. Being too busy from work and money too tight during the pandemic and having my own home gym, it wasn't a necessity.

Fantastic experience: Everything you need, nothing you don’t!

Fantastic experience: Hands down the best place to train in the Boulder AND surrounding areas. There isn’t another gym like it in Colorado. The owner, trainers, members, equipment, and overall atmosphere beats all. If you want a place to succeed in whatever goals you have, this is the place.

Fantastic experience: Hands down the best gym I’ve ever been to! As a beginner to powerlifting I have to say this place is super welcoming to all levels. The equipment at this gym is like no other I’ve been used to, it’s awesome and there’s plenty to work with no matter what your goal is. I can’t put into words how amazing the owners are also, their passion for this gym truly shows.

Fantastic experience: Top of the line equipment.

Fantastic experience: Great gym! Love it!

Fantastic experience: Excellent equipment! Not crowded. Already am in love with the owners.

Fantastic experience: Appreciate the helpful staff...

Fantastic experience: The lifters here are focused and serious, a nice change of pace from the youthful chaos of the CU Rec Center. Professional and friendly owners. Oly platforms are a bit bouncy, but this gym has everything you need for powerlifting.

Fantastic experience: Amazing gym with even better owners. If you’re serious about lifting, there’s nowhere else to even consider. Plus Russell will put you through some killer workouts if you can keep up!

Fantastic experience: Absolutely awesome gym, with a great environment and the best equipment!

Negative experience: Not very good equipment, lacking in some things, powder is not one of them

Fantastic experience: Gab + Russ are dedicated fitness enthusiasts and gym owners. Gym Number Five is a beautiful, well equipped space with a variety of exercise machines that your typical gym does not have. The equipment was carefully selected, bringing adversity and allowing a new training approach that will help everyone achieve their fitness goals. This gym is spacious and extremely clean, complete with a comfy lounge area convenient before and/or after your workout. The 24/7 key code access is also a plus! I highly recommend anyone looking for or wanting to upgrade their conventional gym experience, to check out this gym. You won’t be sorry you did!

Fantastic experience: One of the best gyms I have been too with equipment that I can't find anywhere else. This is the gym to go to if you want to get gains and want access to any equipment around with trained lifters around who are more than happy to help with your form and make you feel comfortable.

Fantastic experience: If you are serious about hardcore training, this is the place to be.

Fantastic experience: Best equipt gym in Boulder by a long shot. There were no last minute thoughts on this gym, every piece of equipment was picked for a purpose.

Fantastic experience: This gym is awesome! Russel, the owner, knows what he's doing and constantly strives to make the place better and better. The people are great, the equipment is the best you can find, and the training atmosphere is welcoming and positive. Whether you're an athlete, powerlifter, strongman, bodybuilder, or just starting out, this is the best gym in the Front Range.
