This practice is great for when you can't get up and down from the floor due to joint injuries, or when the floor is not clean or there is not enough space. I use it in small hotel rooms when traveling or outdoors when camping. As with any form of movement or exercise, please consult with your physician and make sure there are no medical reasons why you should not perform some of these exercises. My aim is to make yoga as accessible as possible. Your task is to listen to your own body (your best teacher) and not move in any way that causes pain or discomfort.
