Hatha yoga is a physical practice that aims to balance the body and mind. It incorporates postures, breathing techniques, and meditation to strengthen the musculoskeletal, respiratory, circulatory, and other bodily systems. Though physical, hatha yoga's goal is overall health and wellness by bringing equilibrium to opposing energies like male and female. Regular practice makes the spine flexible and reduces stress by regulating the subtle energy known as prana. Modern hatha yoga continues to evolve with new scientific understanding of anatomy and health.
