There are many class times to choose from every day of the week so there is no reason not to make it in. Hands down the best decision I have ever made is to join Grinders and continue my membership. I look forward to class everyday and always feel so good when I leave! I highly recommend you coming in to try a free class. I am in the best shape of my life. You will not regret it!

If you're looking for a great place to get in shape, get into or continue competition in BJJ, or…read morejust looking for personal gain; I would recommend Rocky Mountain BJJ for so many reasons. I checked out many places around the area before this one and it was an easy decision to join up. I've been going for just over two months and dropped 20 LBS just going twice a week. BJJ is really a small tight knit community and I like how everyone seems to know each other here and is inviting towards new faces. Chris is an awesome owner and equally awesome instructor. It's my opinion that he's going to grow out of this space soon and for all good reasons. Go check it out; I ended up signing up before my trial was up.

The staff member who helped me was very friendly and gave me a quick tour before I joined. In the initial walkthrough it appeared to have everything I needed to get in my daily workout.

This is one of the few spots we found that isn't class based - though they do offer HIIT and Yoga throughout the week. The gym itself has pretty much all the equipment you would need, the biggest detractor is that it's a quite small space. There's not a ton of open workout space, especially if a class is in session. But they have squished a lot of equipment into the space. So when they're busy it can feel like you're on top of one another. Pretty much only have one set of heavier free weights, so you might end up waiting. Everything is well maintained and clean. The staff are very friendly and the ownership seems to be making updates and keeping the place maintained. Locker rooms are clean. They have garage windows so on hotter days those get rolled up which is nice. There's a small parking lot in the back and some street parking.

I signed up for a "free" 6-week challenge that had been advertised on Facebook. I chose the…read moremembership option ($270 upfront, $180 after the challenge) versus paying $599 upfront for the challenge. I chose the membership option because I was hopeful my work would allow me to actively make time for the gym. Unfortunately, I just wasn't able to complete it do to some changes in my work schedule. Let me just say the workouts, coaches, and people are very friendly. The 6-week challenge meal plan is limited, making it incredibly hard to follow. This comes from someone who is pretty easy-going about meal options and has done low-card, calorie counting, Keto, and a few other meal lifestyles successfully. There's apparently a new meal prep guide with a larger option for foods, but it came out after I started so I don't know much about it. They don't have a copier, so I took a photo of the contract, which is neither here nor there, but more a friendly note to snap a photo or you won't have something to refer back to. They do require you to sign a photo release to join, which really isn't something I was interested in doing, but had already signed up before being told about the release. You're also required to friend the owners, Sol and Amy, on social media and follow the gym. (Funny enough, my EFT just processed for the current month, my last, and I noticed one already unfriended me. I guess that means we can't be friends if my membership during/after my notice. ‍) It's alright. I wasn't thrilled by the idea anyway. Friending them does allow membership in a secret group of other members and one of other challengers. I can't fairly review the gym or the workouts other than saying I would have at least continued to complete the challenge had work not interfered. It is a great workout. You go at your own pace (kind of). Coaches are eager to help (and encouraging) so you don't feel like the new kid. I enjoyed it! My biggest frustration regarding the challenge specifically is there isn't really a good option to just try the challenge. Being asked to pay $600 for a "free" campaign is a lot of money to try something out. When opting for the more price efficient option you're locked into more than 6 weeks because of the misleading 30 day policy unless you cancel after your very first foundations class. The policy states: "Once payment is received on an EFT membership there are no refunds under any circumstances. 30 day written notice is required to cancel an EFT membership. Any payments that fall within that 30 days must be satisfied." MOST IMPORTANTLY: Unless you give notice on the 1st day of the month in a 31 day month, you will be paying for more than 30 days after giving notice. If notice is given on the 2nd or any time after, you'll be billed for the remainder of the current month and then your 30 days. Again, there is no way out of getting locked into a second month automatically when trying the challenge. In my case, I gave written notice just over two weeks after starting, but I paid for an additional month was still due. All in all, I paid $460 for 14 days of foundations classes and 5 days of actual workouts.

By the time I found Soloman I was a mess. Loss of strength, limited mobility and range of motion and daily pain. Not to mention the fear of injuring myself even more. He worked with me for a long time to help regain my mobility and range of motion then we started on strength, it was a special day when he told me we didn't need one-on-one anymore and I could attend the group classes.

Since there isn't a no parking sign in the space my wife replied that she would not move until my daughters class was finished.
