I’ve been to 5 different gyms and by far this gym is the best gym I’ve been to.

I had a fantastic experience at O.N Athletics! The staff was responsive, welcoming, and class was on time. The facility was extremely clean, and I loved that they offer traditional gym equipment in addition to a full CrossFit setup. The 24/7 access is another huge benefit—it provides so much flexibility. I honestly wish my own CrossFit gym offered everything O.N Athletics does. Highly recommend!

My husband and I use both the open gym and CrossFit aspects. We find that all of the equipment (machines, free weights, bars and racks, etc.) is available much more often, and there is just more of it than at other gyms we’ve tried. This means that we’ve never had to wait around to access what we needed or whatever we needed to do that day. The CrossFit coaches are present and attentive, and there are classes available that work with our schedule. Like other CrossFit boxes, there is no air-conditioning in the main gym area. But that’s something that you just expect. And they do have a window air conditioner on one side with a smaller gym area. They also have several bathrooms, a sauna, and a shower. It’s all been very convenient for us and made it easier to stay consistent with our fitness. Definitely recommend.

Great gym for a reasonable rate, the leadership within the gym is very supportive and helpful no matter where you are within your fitness journey. I highly recommend giving it a tour if you’re in the area.

Gym is always clean. I love they have 24hr access to the gym which is great for those on odd shifts and the fitness trainers are on point. If you’re looking for a gym with a plethora of equipment and classes than you’ll find it here.

I really enjoy this gym. It has lots of power racks and a great selection of functional fitness equipment like boxes, balls, kettlebells, and sleds. I’m also a big fan of the sauna. The gym community is great too. Everyone I interacted with has been friendly which makes it an enjoyable place to train.

Loved my experience at this gym! Everyone was extremely welcoming and the staff were extremely helpful. The facilities offered everything I needed from a gym. I strongly recommend Crossfit Dyr to anyone who’s looking for a new gym to workout at!

This CrossFit Box is top notch! The coaches are very knowledgeable and supportive to all levels of fitness and are able to help scale the movements and weight accordingly. It has been an amazing experience becoming a part of this family. I have been working out here for 8 weeks now and have had nothing but a positive experience. Highly recommend joining!
