Zero Machine CrossFit Gym Flooring Testimonial - Soundproof Floor Tile

By Brett Hart Created: January, 2018 - Modified: October, 2023

Zach Luke is no stranger to the challenges presented by CrossFit - from both the fitness and business sides of the sport. The owner of Zero Machine CrossFit in Phoenix, Arizona, Luke and four other coaches run one of the premier Crossfit centers in the southwest United States.

''We have the only CrossFit Games athlete that comes out of Arizona,'' Luke said, referring to coach Tommy Vinas. ''The other four coaches are regional level athletes.''

With such a talented and passionate team of coaches, Zero Machine CrossFits members can't help but to be absorbed by the buzz surrounding the fast-growing sport.

''It's amazing how excited the member base gets just to watch the guys on TV, or girls on TV, and the other coaches,'' Luke said. ''They have personal relationships with them.''

The Problem

One of the problems that comes with the popularity of his gym, however, is that fact that CrossFit exercises often generate a lot of noise and vibrations - something not necessarily welcome to nearby neighbors.

''We are located in a strip mall area, and we were very upfront in regards to the noise situation - the dropping of the weights,'' Luke said. ''Everyone was in agreement (when the doors were about to open just over a year ago). 'That's fine' - until we started dropping weights. Then it became a huge issue.''

In fact, it became such a big issue that Zero Machine CrossFit faced the possibility of losing its lease because of it.

Testing The Solution

So Luke began researching and testing different forms of flooring to see if he could reduce the noise enough to appease the neighbors, landlord and property manager. He even worked with an acoustical engineer to analyze different mats and possibly develop a lifting platform to solve the problem.

Eventually he stumbled upon 2.75 inch thick Sterling Athletic Sound Tiles from, and his engineer friend concurred that the design could make a difference with the noise issue. So Luke ordered four squares to test.

''We were up against the rope - last resort,'' Luke said. ''We didn't have much high hopes for the product.''

However, after testing the Sterling Athletic Sound Tiles with various forms of weight dropping, Luke, his landlord and property manager were amazed at the difference they made.

With the success they had dropping loaded barbells, Luke said they added dropping 70 pound kettlebells to the testing process.

Still amazed by its ability to virtually eliminate all sound, they decided to up their game once again.


Since installing the Sterling Athletic Sound Tiles in the 2,500 square foot live lifting area, Zero Machine CrossFit went from having multiple noise complaints per day to zero complaints.

After all of the time and money he invested in researching and testing different brands of mats, Luke now says, ''I feel like I'm the expert in gym flooring at this point in time. ... You've got to invest in yourself and you've got to invest in your business. ... The flooring works. I would spend the money again in a heartbeat. There are a lot of companies out there making false claims about their matting. They may be testing at 10 pounds, but we don't use 10 pounds - that's the problem.''

''Our members spend a lot of money, they put a lot of faith, a lot of trust in us,'' Luke added. ''You have to give them a product that's worth what they're paying. We take pride in having a gym that not only performs well but looks great.''

** Note: Per the warranty, the recommended usage for the Sterling Sterling Athletic Sound Rubber Tile Black 2.75 Inch x 2x2 Ft. is for weight drops under 90 lbs. and from fall heights under 36''.
