Upa-Yoga is a simple yet powerful set of 10 practices that activate the joints, muscles, and energy system, bringing ease to the whole system. Within the human system, the energy flows along 72,000 pathways called nadis. At the joints, the nadis meet and form nodes, making the joints storehouses of energy. Upa-Yoga activates this energy and also lubricates the joints, creating an instant sense of alertness and liveliness.
