Describe in brief the various elements …

There are three basic elements in yoga: Asanas, Pranayama and Concentration

1. Asanas are poses which exercise the front, back and side of the body equally. A full range of movements such as horizontal and vertical expansion are created while performing asanas. Both the asana and the sequence of asanas are important for creating a response such as stimulating, energizing or calming the body. The asanas also improve muscle strength, mobility of the joints, circulation, and balance as well as body awareness.
2. Pranayama means control of the breath, which leads to deeper breathing thereby providing the body with more oxygen. This intensive breathing technique creates a feeling of serenity and inner peace.
3. Concentration is fundamental in yoga. The focus on the specifics of the pose and control of the breath will improve concentration.
