A set of specific exercises called poses, combined with specific breathing techniques and meditation principles are the building blocks of a yoga class. If a pose causes pain or proves too difficult, some variations and modifications can be made to help students. Props like blocks, blankets, and straps — even chairs — can be used to help you get the most benefit from the poses. Yoga is not one-size-fits-all: The best yoga workout for you will depend on your individual needs and goals. The benefits of a regular yoga practice are wide-ranging. In general, a complete yoga workout can help keep your back and joints healthy, improve your overall posture, stretch and strengthen muscles, and improve your balance.
