I signed up recently with my husband and we absolutely love it here. The owner, Billy, one of the kindest people I’ve met. The sign up process was quick. Billy was super knowledgeable and helpful with everything. 24 hour access!!! I couldn’t ask for anything better!

Merz Built Fitness is a great place to work out, with even better people operating it! The space has everything you need to effectively get an amazing work out in, without having to wait on a bench or machine for an hour. Every time I have went to MBF, I was able to maximize the time I spent there, which is very rare for a gym in this day and age. Also, each time I went, I was excited to see new and state of the art equipment ready for my use. I highly recommend MBF if you are serious about maximizing your time spent in the gym…there isn’t a better place out there!

Hands down the best gym experience I've ever had!
I've been training at this facility for a few weeks now, and it's been a total game changer. The gym itself is clean, well-equipped, and has a great atmosphere—motivating without being overwhelming.
But what really makes the difference is working with Billy. He's not only an incredible personal trainer who pushes you just the right amount, but he's also my nutritionist. That combo has made a huge impact on my progress. Billy takes the time to understand your goals, builds personalized workout plans, and follows through with expert nutritional guidance that’s realistic and sustainable.
I've seen real results—more energy, better performance, and actual visible changes in my body—and I credit that to Billy’s balanced, knowledgeable approach. Plus, he's just a genuinely great guy who cares about your success.
Highly recommend both the gym and Billy to anyone serious about improving their health and fitness!

I had an amazing experience at this gym during my first HIIT workout! I was nervous going in, having never done this type of training before, but Billy instantly put me at ease with his deep knowledge of each exercise and clear guidance. The sense of community in the gym was incredible, making me feel supported and motivated throughout the intense session.
Highly recommend this place for anyone looking to try group workout sessions or just looking for a clean gym with every piece of equipment you could imagine.
