Morning is the best time to practice.
This will adjust your body and mind for the remainder of the day. If you cannot practice in the morning, then evening, several hours after dinner, is the next best time to practice. In the class you will learn a large set of moving and static exercises. For example, in the morning you may want to focus more on the moving exercises to stimulate your mind and body. And in the evening you may want to emphasize static exercises and qj-massage to relax before bedtime.
