Our Members Say It Best...

"a place to succeed"
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.

"Amazing gym!!"
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.

"like no other"
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 used. 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.

"12 out of 10"
Best gym in Colorado hands down. Amazing staff, culture and equipment. Every member is very friendly and everyone from CrossFit athletes to strongmen to bodybuilders are welcome. The staff does an amazing job of ensuring the gym is clean at all times, equipment is in the correct place and creating a family friendly environment. The gym is fully equipped with Rogue, Elite FTS and other top of the line name brand equipment. I can not say enough positive things about the gym. 12/10 would highly recommend.
