Yoga is an ancient form of exercise that focuses on strength, flexibility and breathing to boost physical and mental wellbeing.
The main components of yoga are postures (a series of movements designed to increase strength and flexibility) and breathing. The practice originated in India about 5,000 years ago, and has been adapted in other countries in a variety of ways.
There are many different styles of yoga, such as Ashtanga, Iyengar and Sivananda. Some styles are more vigorous than others. Some may have a different area of emphasis, such as posture or breathing. Many yoga teachers develop their own practice by studying more than one style. No style is necessarily better or more authentic than any other. The key is to choose a class appropriate for your fitness level.
