Rattlesnake Mountain CrossFit

Was working from the airport for a month and needed a place to throw down. This place met or exceeded my expectations. It's a Crossfit gym. Everybody is welcoming and at various levels of fitness. Don't be intimidated. Workouts are short and intense - the thing that brought me to Crossfit in the first place. Thanks Curtis and Michelle for putting up with my chalk mess.

Great place to drop into if you’re in the area. Michelle and Curtis were awesome and welcoming. Gym was extremely clean and everyone did their part to maintain the current standards during these crazy times. Curtis responded almost immediately when I sent a request to drop in. Great location if you’re out near the Hanford site. Enjoyed my time here and will definitely be back.

Update: Came in again on 12/21 after my night shift, and same immaculate box, super nice people just trying to get more fit, and fun programming. Thx again for a good visit! Very clean, and well-run box. Curtis was super accommodating and took us through the w/u, strength, METCON WOD session efficiently...with just the right amount of coaching/pointers. Super impressed with the cleanliness and workout gear...amazing the place is 4 years old! Smaller facility next to a brew pub, but friendly folks and good programming. No typical Crossfit douchery here. $15 dropin fee and cool merch to buy. I'd gladly visit again!

My husband has been wanting to try Crossfit for a long time, but I've always been very intimidated by it. I always felt like I had to be in shape first. Gym routines just weren't working as it is so hard to stick to them and you have to come up with your own plan. I'm so glad we chose this Crossfit gym to start this type of workout. The coaches and members have been so welcoming and helpful. My husband and I can both go do the same workout but at our scaling options which is really nice! It's been a hard couple of months getting use to the cardio level and learn the movements but it's been well worth it! They really focus on doing the movements safely and effectively! -Julie Milam

I recently moved from the Seattle area to Richland. One of the first calls I made when I arrived was to Curtis at Rattlesnake Mountain Crossfit. RMX is three minutes from my home, so I was really hoping it would be a good fit as.I searched for a new CrossFit community. I couldn't have been more pleased. From that first phone call when Curtis described RMX and their approach, I could tell it was going to be good. When I arrived, I saw the cleanest Crossfit gym I've ever visited. And then experienced a workout led by encouraging, friendly, intelligent, and proficient coaches. If you are looking for a CrossFit gym—or even better, are thinking about starting CrossFit for the first time—this is where you need to be. Curtis and Michelle have created a culture of community that stands out and their encouraging attitude will welcome the experienced CrossFitter as much as the novice. See you here soon!
