Aloha RodB,
The Level I active exercises are very helpful in removing blockages and balancing the yin and yang energy.
They are also extremely important because they will set the person up to move blocked energy out of the body and go deeper into their sitting meditation.
Chunyi has recommended doing 75% level I active exercises and 25% sitting meditation at the begining of one's practice, or if they're working through some physical illness/blockage.
Much Love, Shawn
