Hi all; best yoga styles are
Ashtanga Yoga:This focuses on the flow of postures in order to improve strength, stamina and flexibility of the body. During a Asthanga Yoga class, the participants jump from one posture to another. If you are interested in improving your strength, flexibility and stamina and you are fit enough to deal with an hour of jumping from one posture to another, Asthanga Yoga can suit you. 
Power Yoga:This is an American development of the Asthanga Yoga that also adopted several elements from other types of yoga styles. You can find Power Yoga classes mainly in fitness and health clubs. Power Yoga focuses on strengthening the body by performing Hatha Yoga postures for a longer time to improve both physical flexibility and mental focus. Power Yoga can be a good exercise for athletes, people who practice types of fitness activities and people who want to tone their body.
Bikram Yoga:A Bikram Yoga class features a series of 26 Hatha Yoga postures practiced in a heated room. It is also known as Hot Yoga. The purpose of the heat is to allow the participants to get into each of the yoga poses in a deeper and safer manner. The heat also helps clean the body from toxins promoting sweating. Bikram Yoga focuses more on the workout of the entire body, including the internal organs and less on flexibility. Bikram Yoga is not recommended to pregnant women and people who suffer from high blood pressure and heart conditions, but it can improve the physical fitness of people who recover from injuries.
Iyengar Yoga:This focuses on the physical alignment of the body and the accurate performance of each posture. Some of the Iyengar Yoga postures are practiced with the assistance of props such as blocks and belts that are designed to help the participants achieve the most accurate posture and to protect their bodies from injuries. Since the flows between postures are not practiced, Iyengar Yoga classes are less intense and therefore more suitable for people who are less fit. Iyengar Yoga improves body strength and flexibility and can fit people of any age and every physical condition.
Cheers :)
