The energy flow series through all sixteen muscle groups in a specific order. This order brings energy from one meridian muscle group and its associated organ to the next.
As per Traditional Chinese Medicine (TCM), energy flows from one meridian muscle pathway to the next in a very specific order. In TCM this order is called the 'energy cycle'. This order is determined by the depth of the muscles in the body and begins with the muscles associated with the gall bladder, with the next always being its balancing muscle group, in this case liver, and then on through all the rest. The cycle always includes two lower body, then two upper body meridian muscle groups, and then repeats two more of each. Ultimately all 16 have been completed.
