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. If you have an injury or arthritis it is important to tell your instructor so that he or she can advise you about modifying the exercise.
Proper posture is very important to prevent discomfort.
Many have a lifetime of poor posture leading to weak muscles, ligaments and tendons. Correcting your posture during exercise often results in the student experiencing shakiness, cramping, or soreness in weak muscles and joints. Focus on correct posture and over period of weeks or months gradually increase the time you spend in a static position. Some have described it as a life force or universal force. Others believe it is connected to the bio-electrical system of the body.
