There are a series of connective tissues that run through the body called myo fascial trains. Most of these run the length of the body and they are integral to our ability to move as a whole unit and generate a sense of biotensegrity. As opposed to isolating muscles, muscle groups and joints - see classic gym resistance training.
Here is a clip introducing the anatomy trains featuring Thomas Myers. Thomas Myers studied with Drs. Ida Rolf, Moshe Feldenkrais, and Buckminster Fuller, and with a variety of movement and manual therapy pioneers. Tom is the author of Anatomy Trains (2020, 4th ed).
One of the aspirations of practicing Circlework is to train and develop the ability to feel and manifest whole body movement. We practice to get out of our joints and muscles and feel how we can transmit force from the earth and to the earth via the fascial lines.
We start with the feeling of foot to core and then hand to core and then connect to get to a whole body state.
The clips below illustrate a developmental process from stillness to dynamic movement. Ideally you need a partner to practice with.
1) Solo practice
2) Solo connected
3) Partner stationary
4) Partner dynamic
