Tai chi, also called tai chi chuan, combines deep breathing and relaxation with flowing movements. Originally developed as a martial art in 13th-century China, tai chi is now practised around the world as a health-promoting exercise.

While there’s scope for more rigorous research on tai chi’s health benefits, studies have shown that it can help people aged 65 and over to reduce stress, improve posture, balance and general mobility, and increase muscle strength in the legs.
