I was never much of an athlete before, but this place changed everything for me. It's the BEST workout, for your body and mind. The classes are challenging, but instructors and students are super supportive and encouraging. There are also a lot of different types of classes you can take, so you never get bored.

I started out with the free Women's self defense class and it was a great workout and I learned so much that I decided to keep coming. The martial arts school really works as a family where everyone encourages each other to succeed in every part of life. It is so worth it to gain empowerment, strength, and discipline. I appreciate everyone there!

Awareness on protecting yourself
Women's Smash Classes are EXCELLENT and they are FREE.
I dropped in as suggested by a friend and I wasn't disappointed.
Maybe out of shape a little as they have you warm up before class which is definitely a work out. The on hand techniques that are shown are always described in full detailed by the one and only...head of the Academy. His stories and insight never cease to amaze me but it's all for a reason. It's life and you need to be aware of how to protect yourself.
I'm glad I've taken several classes and was able to share what I've learned to my female co workers with a sense that taking action and educating is the key to protection. I've enjoyed my time there although I'm not able to attend more classes currently...what I've learned will go a long way. Thank you to all the instructors and helpers you made me a more stronger and aware person. AKA Joy Daniel.

The women's self defense class is a wonderful program that's offered for free. They teach you how to get home safe. I love their techniques. It's worth trying.

I've studied here for 11 years, and have probably only just scratched the surface of what this school and its instructor, Sifu Jack Shamburger has to teach.

This school offers a free women's self defense course twice a week. It covers reliable ways to stay safe out there.

Whether looking into martial arts, personal defense, or just for a fun workout, this is THE place you want to try even if it takes some travel.

Cannot recommend enough. You will grow in so many ways.

I walked away from this class feeling knowledgeable and empowered. Sifu and the rest of the CHKA instructors were very helpful and made sure the entire class understood the self-defense moves by providing one-on-one practice. I now understand the importance of making self defense a personal practice- it truly takes time to develop. Taking one class is not enough to develop the muscle memory needed to beat an attacker. All females in NYC should take this class. Thank you CHKA!

We recently had Sifu Jack come in our office and provide a presentation. In a short amount of time we learned a lot of basic moves. He definitely left a lasting impression on all of us! We look forward to taking the class in the near future.

I visited this academy on a Tuesday evening for their free self defensive class and had an amazing experience. There were three instructors and the owner who taught the one and half hour class. Thank goodness we had a small enough group that we were able to each participate several times to learn the techniques. Staff were very patient, helpful and easy on the eyes (the men :-)). There were a few students who have been there a few times and some of the instructors knew them by name. At the end of our class I was waiting for some sort of sales pitch to get us to sign up for some of their paid classes and there was none. We had a pep talk on safety precautions living in NYC and were on our merry way. I will definitely return to another self defense class and check out some of the other classes they offer.
