When practicing yoga, it is important to have the proper props to ensure that you are able to maintain correct form and alignment. Yoga blocks can be very helpful in this regard, as they can provide support and stability when needed. Cork blocks for yoga boasts the more heavy and dense support, while yoga foam blocks are lighter. They can be used in a variety of ways, such as under the hands or feet, or even propped up against a wall. Whichever type of block you choose, make sure that it is firm enough to provide support but soft enough to be comfortable.
