How is this the first review on this gym?…read more Boulder mountain is a great gym! I wasn't sure what to expect in a smaller town like this but I was impressed! Great trainers, great workout buddies, and great structure. The workout was awesome, the gym is very organized and I loved my workout!

From the owner: The Valley's Premier CrossFit Facility…read more Come see the difference experience makes at Boulder Mountain CrossFit. Our coaches have more experience than anyone else in the area, and that translates to better training and better results for you! We're also the largest facility in the area, with more high-end CrossFit equipment, classes and open gym times than any other gym in Hailey. That's just one reason you'll see people from all walks of life - from grandparents to students to elite athletes - training in our gym. But sticking with a fitness program really is about more than results, and we know that. You've got to ENJOY your workout if you want to stick with it! For that, we've got passionate, intelligent programming, an awesome community that loves to have a blast at the gym, and a feel-good vibe that hits you as soon you walk in the door. Come check us out and feel it for yourself! All our classes are designed to deliver two things - results and fun! We know you won't stick to a workout regimen that you don't love, so we work hard to make sure every class gives you the best hour of your day, all while giving you noticeable results in a safe, supportive environment. We offer: CrossFit Masters CrossFit Teen Strength and Conditioning Personal Training And our newest program - Ignition! A great place to "start your engine" if you are new to working out, or if you prefer a lower intensity version of the CrossFit training program. Think of it as CrossFit Lite.

Whether you are a pro athlete or an out of shape,out of altitude, knee recovering, middle aged…read moreperson like myself- Bill and Naty are the best I've ever worked out with. It is the hardest most efficient workout I've ever done but in a fun supportive group setting with a great music playlist! Talk about a post workout high! They specialize in full body plyometric movements to improve coordination as well as isolating muscles to utilize one side of the brain for best muscle building efficiency. Who knew? They did from years of research and experience. They have it down to a literal science! 10/10 would recommend even if you are afraid or out of shape or inexperienced! They will teach you how to train like a pro!

I was so impressed by my session with Bill at HardCore. I work out regularly and know my way…read morearound a gym so didn't think HardCore would be that different than a regular studio training session. Boy was I wrong! HardCore was a really creative, effective way to change it all up. Think TRX completely, brilliantly redesigned and expanded upon by physiology geniuses. As Bill led me through a full body workout I was engaging so many muscles in new, smart ways with the proprietary equipment. And as tough as this workout was, it was very low impact, felt utterly safe, and I felt no stress on joints the way regular weight lifting can do. Even though I wish I could do weekly sessions to incorporate HardCore into my fitness routines, I am so glad I tried this while visiting and will definitely go back when I visit again.
