How to do tai chi for seniors
Try a breathing exercise.
Breathing is one of the most important parts of practicing tai chi, so a basic breathing exercise can serve as an introduction to the discipline. Maintaining deep, repetitive breathing is calming in and of itself, even if not combined with specific tai chi movements.
Think of your breath as a circle-in through your nose and out through your mouth without holding your breath or stopping at any time. There should be no pause between the end of your inhale and the end of your exhale-it should be one continuous circle.
