We have been offering this free walk-in, self defense class as a service to the women of our NYC community for close to 30 years.  The class focuses not only on self defense techniques, but also on ways to prevent becoming a victim – the first line of protection is common sense!

Proper punching and kicking techniques are emphasized, as well as techniques for taking down one’s attacker. Sifu Jack incorporates the knowledge gained in his years as a bodyguard, US Marine, and competitive martial artist to help you defend against your potential aggressors.

The SMASH class is the longest continuously-running free class of its kind in NYC. Women 14 and older are invited to attend as many times as they like.

There is never a fee charged for the SMASH! class, and you are welcome to attend as many times as you like. We do ask that you make a small one-time donation to the school by purchasing a CHKA t-shirt to wear to class. CHKA t-shirts are $25.
