Sometimes a Shorter Set is in Order
If you are short of time and still want to get some Qigong in, you could do an abbreviated set using the Five Flows idea. Do one exercise from each type of Flow.
Or maybe you are showing a friend or family member a little Qigong and you want them to experience it, but doing a complete set seems too much. Five new exercises are easier to grasp than 12 or more.
A Short, Yet Complete Set from Five Flows Qigong
#1: Shaking the Body
#4: Outer Qi Shower
#6: Charging the Qi Ball
#10: Riding the Waves
#12: Centering the Qi
Many-Rep Single Exercise Set
Another method you might want to work is to take one exercise and perform it over and over and over; dozens, scores or hundreds of times. As long as you are not hurting yourself by overdoing, you could gain a lot of healing shifts from such a mega-single-exercise-practice.
The reason to do one exercise of Qigong over and over is not for the high number of reps. It isn’t quantity you are seeking but the ability to get deeply, comfortably familiar with the exercise and gain much greater effectiveness.
By deepening in this way, you come to understand the exercise more and are able to let it expand in all it’s possibility through your body.
