My first class was amazing. I am a beginner and the instructor did an amazing job transitioning me into the group and showing me techniques with exercises I struggles with. I love the class and am so happy I signed up. At 38 discovering a new sport for fitness that I enjoy is very surprising.

My 5 year old daughter started in the lil ninjas class last Sept and in just 4 months we have been amazed at the progress she has made.

There has been a huge improvement in her overall coordination, flexibility, and confidence.

I would highly recommend xtreme ninja school to any parent.

How many of you couples out there are looking for some nights out where the atmosphere is friendly ,supportive and the people are great! Well sign up for some kickboxing at Xtreme Ninja Martial Arts and I promise you a whopping good time. If you are going out to bars for appetizers and beers a couple of times a week, then this is much healthier an much more FUN choice. At the end of a year who will feel or look better? Those of you who eat appetizers or the ones that choose to burn those nasty calories. NO Brainer DO It!

I went to Extreme Ninja while visiting the area. I plan on moving to to the vicinity in the near future and I wanted to check out a school that I may eventually enroll in. I was welcomed with open arms and felt as though I had been going there forever. I was treated extremely well by the owners, instructors and even the other students. I can not say enough about their friendliness and professionalism.
