It differs from aerobics, step and boxercise in that it is a system of internal rather than external exercises that strengthens your immune system and increases circulation. Using the ancient Zhan Zhuang system, this video presents a step-by-step method that stimulates, massages, cleanses and revitalises the internal body, enhancing physical energy and improving your health and general well-being. It is claimed that the efficiency of the internal body will be improved, and will extend to the outer body, burning fat and toning muscles without strenuous exercise, making it the perfect fitness class for everybody of all ages to enjoy.
