From the reviews
Couldn’t have made a better decision on the place we chose to send our son for his Karate and Muay Thai experience. Nothing but great experiences with the whole staff. Very family orientated, personable, excellent values taught, confidence building at it’s finest.
Before I moved to the area and came to Xtreme Ninja Martial Arts & Fitness Center, I was not exercising, unhappy, overweight, and anti-social. Since I began training and exercising here for the past five months, I have a lost 20 pounds so far and I now live a healthier and happier lifestyle.
Very friendly and experienced trainers here to help with various fitness methods. Self defense and kickboxing and amazing boot camps and intense classes that are completely rigorous in all the right ways. They offer classes ranging from fitness and well-being to high level martial arts and everything in-between.
I have really enjoyed taking classes (Kickboxing & XFit) with Xtreme Ninja over the past two years. Not only did I lose 20 lbs within the first six months of my membership, but I have been able to maintain my new weight and gain more muscle. I am stronger and leaner.
Your first kickboxing class at Xtreme Ninja Martial Arts & Fitness Center
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.
