Hatha yoga focuses on posture and breathing techniques, traditionally to channel vital energy source. In Sanskrit, Hatha translates to force. The practice involves breath, body, and mind, and classes are usually 45 minutes to 90 minutes of breathing, yoga poses, and meditation.
Hatha yoga breathing techniques can be traced back to the 1st Century in both Buddhist and Hindu texts, but it was another 1,000 years before the use of yoga postures, or asanas, and breath control was recorded as a way to enhance vital energy.
