Yoga

Yoga is a non-completive activity generally regarded as a series of physical poses, stretches and relaxation exercises. This is only one of the eight "limbs" of yoga, other elements of yoga concentrate on mental and spiritual wellbeing and the focus of yoga classes can vary depending on the individual teacher and the yoga tradition in which he or she was trained.

The interesting thing about yoga is that your experience is always evolving and changing. Although the poses themselves do not change, your relationship with them will, as you improve your knowledge and ability. Anyone can start, even if you don't feel like you are very flexible or very strong. These things will develop over time with regular practice.
