After only 2 years of training I started to see real results: better posture, stronger core, more energy and endurance. Our Shi-fu is the real deal! He really cares about his students and works very hard to make sure the student is doing everything correctly. Training in Tai Chi and Qi-Gong is hard work but it pays off. I practiced external martial arts in my 40's, mixed and Filipino, but since joining the Mantis Institute I feel even more fit and centered then I did during my external martial arts practice. I highly recommend our school to anyone who is looking for a life time of improving health, posture, energy and mental and physical well being. I especially recommend it for ex martial arts practitioners who due to injury or getting older can no longer practice their art.
