Tai chi is a slow, flowing form of exercise that’s sometimes described as “meditation in motion.” The practice involves a series of choreographed moves with evocative descriptions, such as “grasp the sparrow’s tail” or “wave hands like clouds.” As your body moves, your mind has to focus. But tai chi also encourages relaxation, which helps ease stress. Those features are all important aspects of mind-body therapies, many of which seem to benefit heart health, says Dr. Gloria Yeh, associate professor of medicine at Harvard Medical School. “On a simple level, tai chi is a very accessible form of exercise,” she says. The movements are easy to adapt to different levels of intensity, and you can even do certain movements while seated in a chair. Tai chi doesn’t require fully extending or stretching your joints, so it’s also fine for people who are not so flexible.
