Welcome to CrossFit Mile Zero in Key West, FL – Key West's premier CrossFit gym and fitness training. Come in today for a free trial class!

At CrossFit Mile Zero, all athletes who are new to CrossFit begin by working 1-on-1 with one of our coaches. We take our time to familiarize you with our movements

Completion of the Foundations Course gets you into Key West’s most tight-knit fitness community. CrossFit Mile Zero offers a semi-private training experience in every class.

The coaches were great! Welcoming and friendly! My husband needed to video some workouts to qualify for a competition and they helped get him set up during open gym. The class I joined – the whole class greeted me and encouraged me! I will definitely be back when we visit Key West again.–

My husband and I dropped in today and would highly recommend this box to anyone. The coaches were awesome and the WOD was great. Thanks for having us!!!

I had the opportunity to drop in while in town. Fantastic gym! Fantastic and friendly coaching staff and members! Thank you so much. I highly recommend to anyone!

Fantastic experience: While on vacation, I was addicted to get my sweat on here at CrossFit Mile Zero. It had everything I was looking for: kick butt workouts, clean facility, Rogue equipment, knowledgable coaches, and a great sense of community. If you're in the area, I highly recommend CrossFit Mile Zero.

Fantastic experience: I came to Mile Zero having just recovered from knee surgery. The coaches were very accommodating with helping me modify where I needed to. I slowly was able to build back my strength thanks to this gym. All the coaches learn everyone's name and classes become like family. Crossfit gyms can be intimidating but this gym is so friendly and welcoming. Great workouts and great people!

Fantastic experience: Dropped in at CrossFit Mile Zero with my husband this morning. Folks were very welcoming— so much so that my husband commented, ‘the friendliest people we’ve met on our trip have been from CrossFit!’ They follow the Mayhem Affiliate programming so had a good combo of strength + conditioning. Gym is beautiful spacious, lots of equipment. Highly recommend!

Jonathan Miller 2 years ago

Fantastic experience: Absolutely love that this CrossFit had a kids program. This is also a great CrossFit for adults, which is a good thing since it's the southernmost CrossFit in the continental US. Great atmosphere and people. I attended with my family for almost two years while living there. Check it out.

Fantastic experience: Afraid you won’t know what to do when you go? Afraid everyone will be staring at you? Worried you won’t be good at it? Let me start with this. Jeff and his staff are nothing short of amazing. When I walked in people said hello and Jeff pulled me into a private room to teach me the basics. He went through movements thoroughly and explained his process clearly. Jeff’s first goal is to make you feel comfortable and understand how to safely work out. He takes a lot of time to explain how to work out properly. While working out there are coaches that will keep their eyes on you to make sure you are working out with good form and have a full understanding of what you’re doing. I will be attending more often because of Jeff and his staff! Great job!

Daniel 4 years ago

Fantastic experience: Dropped in very late for 19.4. Stephen was running the class. Set me up quickly and professionally so he could get back to the class. Then he stayed late to judge me and coached me through it. Greatly appreciate his professionalism, positivity and time. The location has a nice setup. It's small(I'm from OKC, our gyms can't be big enough haha), but the layout is well done. They have a marked run path out back, per the norm. Well stocked on gear and equipment. The class was all friendly and Stephen was very involved with them during it. 5 outta 5 baby!

Jason Silverstein 4 years ago

Fantastic experience: Awesome box! Jeff was super welcoming and a really down to earth guy; he's a testament to how personable and genuinely human CrossFit affiliate owners are. Vanessa led a great warmup, strength session and workout - it was a challenge and it was fun. I was just dropping in but my impression was that she's a pretty cool person and cared about what she was doing (didn't see her check her phone once). Big space, all the toys, and the temperature and humidity are under control, plus they make it very easy for visitors to drop in. Bottom line: if you're here for vacation, then find some time to drop in and have the workout you know that you have to have.
