Vinyasa Yoga focuses on intentional movement, alignment, and conscious breathing. This style is sometimes also called flow yoga, because of the smooth way that the poses run together and become like a dance. The breath acts as an anchor to the movement as you to flow from one pose to the next in time with an inhale. Like all styles of yoga, Vinyasa has both mental and physical benefits. Physically, sweat expels toxins and re-energizes your body. Mentally, the synchronized breathing relaxes your mind and helps to release any blockage of energy flow throughout your body. 
Vinyasa Flow began as Ashtanga Vinyasa Yoga by a Yogi named Sri Tirumala Krishnamacharya. He was given a place to teach yoga and eventually taught a young boy named Parrabhi Jois his learnings on the power of breathing. Jois then established an institute for practicing the specific form of Vinyasa yoga.
