I started learning hsing I. The people I study with have never heard of the particular set of exercises from your book. What is a good way to explain the purpose of hsing I nei gong in relation to how it enhances hsing I training? Does xyn relate more to the animal forms? Thanks in advance.

The Nei Gong set is designed as general physical preparation training, including power training and overall conditioning exercises.

The emphasis is on mind and body unity, and the included exercises provide all round training for the whole body, good for health and also as a foundation for more advanced Xingyiquan practice.
