No, you do not need any special equipment for yoga practice. All you need is a comfortable space and clothing that allows you to move freely. You may also want to have a yoga mat, blocks, and straps to help you with certain poses.
Both online and brick-and-mortar retailers and sporting goods stores offer a variety of yoga equipment. Wherever you buy it from, reading the reviews first helps ensure that you’re getting a product that meets your desired specifications and level of quality.
You should familiarize yourself with the props described below but you don’t need to buy your own unless you’re starting a home-based yoga practice because they are almost always provided by studios and gyms.
