There are many types of yoga, but the most common types are Hatha yoga, Ashtanga yoga and Vinyasa yoga, which can be suitable for beginners. Hatha yoga is a gentle form of exercise that focuses on breathing techniques. Ashtanga yoga is a more rigorous version with eight limbs or steps: yama, niyama, asana, pranayama, pratyahara, dharana, dhyana and samadhi. Vinyasa yoga is based on the flow of postures with synchronised breathing which also incorporates elements from other styles such as Iyengar.
