While yoga can help you keep your balance and prevent falls, another practice that is considered excellent for balance is Tai Chi. This is practiced by millions in China and has only recently become more well known in America. It is a series of gentle, flowing movements. Tai Chi is safe and easily performed by most people. You must be able to stand without help, though.
Tai Chi is still not as popular as yoga, and you may have more difficulty finding a class in your area. With some research though you may find a class at your senior center, hospital, or fitness center. If not, perhaps you could suggest they do so. Many doctors are discovering the advantages of tai chi and recommending them to their older patients. Tai chi is best learned with an instructor. It appears to be simple, and it is at the beginning with the basic moves, but it can get harder to follow or master later on. In this case, practice will make perfect. There are some good videos on YouTube that can introduce you to it.
Seniors need to keep active as they get older to avoid joint and muscle pain. Even if they feel they are not capable, they at least should participate in a gentle or chair yoga class. Also, a tai chi class can be helpful. Without movement, the muscles and joints will become stiff and harder to move. Yoga and tai chi are safe, easy ways to keep those aches and pains at bay. Both can also help with balance issues and help prevent a fall.
