"We do both qigong, and tai chi, which are similar. Qigong is standing still and doing exercises for the whole body, whereas tai chi is a moving form, a little bit like a sequence of movements, or a dance. It’s all very much in slow motion. The slower you do it, the harder you actually work in your body, and your brain, because they’re not used to doing things so slowly.
Where karate is an external martial art, tai chi is an internal martial art, exercising organs in the body like the heart, kidneys, liver, spleen and stomach and digestive system, the spine, and the sympathetic and parasympathetic systems."
