Incorporating traditional hatha yoga asanas (postures), Sivananda style yoga also includes instruction in pranayama (breathwork), meditation, and relaxation. While hatha yoga builds strength and increases flexibility, pranayama is noted for increasing creativity and clarity of mind. Core body strength and flexibility are increased and awareness of the breath and its role in generating and preserving energy in the body/mind/spirit is increased. All asanas are able to be modified to be more challenging, enabling students of all levels to meet and increase their capabilities.
