Types of Yoga :
There are many types of yoga. Hatha (a combination of many styles) is one of the most popular styles. It is a more physical type of yoga rather than a still, meditative form. Hatha yoga focuses on pranayamas (breath-controlled exercises). These are followed by a series of asanas (yoga postures), which end with savasana (a resting period).
The goal during yoga practice is to challenge yourself physically, but not to feel overwhelmed. At this "edge," the focus is on your breath while your mind is accepting and calm.
