I started Tai Chi at the beginning of 1987. A friend of mine who was a Tai Chi instructor finally convinced me, after two years of effort, to have a go. At that time I thought Tai Chi was only for elderly people and I wasn't keen on moving around slowly for exercise.
I went to my first lesson and was hooked.
After 35 years I'm still practicing and teaching Tai Chi. Why? Because I've discovered there is much more to Tai Chi than a slow form, and that still fascinates me. The range of training includes the hand form, Push Hands, Weapons (sword, sabre, spear), Nei Kung, and Self Defence. Within in these aspects I can strengthen the body, calm the mind, energise, stretch, breathe correctly etc etc.
I could never apply myself to any other form of exercise because I'd be bored and stop doing it after a short period of time. Though I know others do find an alternative to Tai Chi and are dedicated to their own exercise programs.
Tai Chi for me is a lifestyle and not just an exercise. Obviously I'm biased after 35 years of practice!
