Yoga is a Sanskrit word meaning to yoke or unite the source of our being.
Yoga is a combination of poses and postures (asanas), breathing (pranayama) and meditation that focuses on stress reduction, and toning muscles.  This is achieved through slow, dynamic movement.  
These techniques increase strength, endurance and energy.  There is low risk of injury to muscles and ligaments as it is a non-competitive exercise regiment performed at one’s own pace.
The poses energize and promote internal awareness through breath control and mind-calming meditation.
