From the reviews
The Grindhouse is the best mma, jitsu gym in surrounding states. Anyone who goes to this gym learns something every time they go. The athletes who train there, compete with the very best. The environment is friendly and not intimidating. Will, the owner is very professional and friending. He is the best instructor.
The only intimidating thing about walking into this MMA gym is the step before you touch the door. Once the unknown is out of the window this group has been one of the most welcoming/nice environments that I have experienced. It's an amazing place to figure out the type of person you are, and who you could become.
After moving to Billings for work I wanted to try out Jiu-Jitsu as I had wrestled my whole life. I also had recently done some boxing training and wanted somewhere to train in that aspect as well. The Grindhouse DOES IS ALL!!!! Jiu-Jitsu, Boxing, mma, Gi, NoGi, womens only classes, children’s classes!
I was in town for a few months and couldn’t ask for a better place to train. Will is a great coach and extremely knowledgeable. Everyone that trains here are very welcoming and friendly. Ive been to gyms around the country and this one has them all beat.
New to kickboxing? Start at The Grindhouse
The Grindhouse comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first kickboxing class at The Grindhouse
Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
