Because it's slow, tai chi is well suited to seniors who want to keep in shape. Nevertheless, as the expression goes, "Only by learning to go extremely slow can you learn to go extremely fast." Going slow cultivates true strength, and by practicing slowly, you will cultivate a strength that is startling when applied.
因為慢，所以太極適合中老年人養生，不過所謂「能慢到十分，才能快到十分」，緩慢中培養悠長紮實的勁道，蓄勁而發時，力道更驚人。
