Asanas 
Yoga practice begins with the outermost aspect of our form, the body. Asanas (set movements) help to keep the body healthy by removing tensions and massaging the internal organs, thereby improving their function and giving greater flexibility to the spine, muscles and joints. 

Pranayama 
Pranayama is the exercise of the breath. Breathing techniques are important within Yoga not only for improving the supply of oxygen to the body but also for strengthening the lungs, but the way we breath also has a direct effect on the brain and emotions, balancing the nervous system and putting us in touch with deeper energies and many other aspects of our being.
