From the reviews
I've tried several gyms and could never find a place that I felt like I could fit in or be comfortable or get motivated to achieve what I wanted. MMA Underground is hands down the best experience I've ever had in a gym. Oscar is a wonderful instructor with an extensive martial arts background.
MMA Underground has changed my life for the better. The trainers and students are absolutely amazing. Anyone is willing to help you out and help improve your weaknesses. If you want to become a great fighter quickly this is the place to train at.
VERY NEWCOMER FRIENDLY! I trained here for about a year and a half. Unlike larger gyms, training was very personal and the sensei was constantly reviewing techniques and movements during drills.
I am so GRATEFUL to have found this dojo. Sensei Oscar is a amazing teacher.He also is a wonderful example of a man who incorporates not only his teachings but his thoughts of who a truly good person is. I have personally seen awesome transformations of the MMA fighters who train there.
New to kickboxing? Start at Mixed Martial Arts Underground
Mixed Martial Arts Underground comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 Mixed Martial Arts Underground
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.
