Tai chi, sometimes called tai chi chuan, is a noncompetitive, self-paced system of gentle physical exercise and stretching. To do tai chi, you perform a series of postures or movements in a slow, graceful manner. Each posture flows into the next without pausing.

Anyone, regardless of age or physical ability, can practice tai chi. It doesn't take physical prowess. Rather, tai chi emphasizes technique over strength.

Tai chi is used to:

Reduce stress

Increase flexibility

Improve muscle strength and definition

Increase energy, stamina and agility

Increase feelings of well being

Tai chi has more than 100 possible movements and positions. You can find several that you like and stick with those, or explore the full range. The intensity of tai chi varies somewhat depending on the form or style practiced. Some forms of tai chi are more fast-paced than others, for instance. However, most forms are gentle and suitable for everyone. And they all include rhythmic patterns of movement that are coordinated with breathing.

Although tai chi is generally safe, consider talking with your doctor before starting a new program. This is particularly important if you have any problems with your joints, spine or heart.

Stress reduction and other benefits of tai chi

Like other practices that bring mind and body together, tai chi can reduce stress. During tai chi, you focus on movement and breathing. This combination creates a state of relaxation and calm. Stress, anxiety and tension should melt away as you focus on the present, and the effects may last well after you stop your tai chi session.

Tai chi may also help your overall health, although it's not a substitute for traditional medical care. Tai chi is generally safe for people of all ages and levels of fitness. Older adults may especially find tai chi appealing because the movements are low impact and put minimal stress on muscles and joints. Tai chi may also be helpful if you have arthritis or are recovering from an injury.

Despite its ancient history, tai chi has been studied scientifically only in recent years. And that research is suggesting that tai chi may offer numerous other benefits beyond stress reduction, including:

Reducing anxiety and depression

Improving balance and coordination

Reducing the number of falls

Improving sleep quality, such as staying asleep longer at night and feeling more alert during the day

Slowing bone loss in women after menopause

Lowering blood pressure

Improving cardiovascular fitness

Relieving chronic pain

Improving everyday physical functioning
