Read the text carefully and answer the question no. 3.

Yoga is a kind of posture and breathing exercise. It brings together physical and mental disciplines to achieve peace of body and mind, helping you relax and manage stress and anxiety. Traditional yoga puts emphasis on behavior, diet and meditation. But if you're just looking for better stress management- and not an entire lifestyle change - yoga can still help. Yoga trainers gradually choose easier to complex activities for practitioners. However, all practitioners do not necessarily need the same kinds of practice.
