Our kiddo is so excited to start training here. We had tried other places but he didn't take to it so I was convined he would not like it but since the first day we tried class he gravitated toward Master Ben. Excited for his journey!
Great show at the Waves game!
I’ve had many fantastic experiences with Underground fitness and Self Defense! My kids got so much from weekly classes with master Ben, they are currently yellow belts and I’ve seen the benefits of taking them consistently.
I’ve also hired them to provide Women’s Self defense classes at my office which were so educational and empowering, the ladies that attended have told me multiple times that they are glad they attended and feel a little more confident in defending themselves now. I highly recommend them for kids classes as well as for adults. Plus, who doesn’t want to join a lightsaber club?!
