1. Proper exercise (Asanas)
The asanas (postures) work systematically on all parts of the body, lubricating the whole bodily system by stimulating the circulation and increasing flexibility. Asana means a steady posture done slowly and with awareness and promote not only physical well-being, but increase mental capacities for concentration and meditation.
Yoga asanas work first and foremost on the health of the spine. The spinal column contains the central nervous system, the communication system of the body, supporting the health of the whole body.
If the flexibility and strength of the spine is maintained with proper exercise, circulation is intensified, the nerves are assured of a supply of nutrients and oxygen, and the body retains its youthful condition.
Moreover, asanas activate pressure points which when stimulated, increase the flow of prana (life force or vital energy) in the body. They massage the internal organs resulting in improved functioning. Since yoga asanas are always practised in conjunction with deep breathing, relaxation and concentration, they help to develop mental concentration. The restless mind is withdrawn from the outward distractions and turns inward and is stilled.
