How often should I practice?

Preferably daily, but at least three to five times a week, for a minimum of 10 to 20 minutes per session. Martial artists and athletes can use chi gung or tai chi as a warm-up exercise before their main work out. Office workers can practice during lunch and short breaks. Even a few minutes can help dissipate stress before it has had a chance to settle in and increase. See The Big Book of Tai Chiⁱ, Chapter 4, for more on dealing with stress.
