Hatha Yoga

Hatha yoga refers to a set of physical exercises (known as asanas or postures), and sequences of asanas, designed to align your skin, muscles, and bones. The postures are also designed to open the many channels of the body—especially the main channel, the spine—so that energy can flow freely.
It is an old system that includes the practice of asanas (yoga postures) and pranayama (yoga breathing exercises), which help bring peace to the mind and body, preparing the body for deeper spiritual practices such as meditation.
