The great thing about yoga is...it's meets you where you are and we teach that you work from your authentic place. This remains true,however, by having the right equipment and accessories, you can focus on what is most important: the journey to improvement.
Accessories and yoga props can help improve your practice by giving the extra inch you need to hold that pose or feel your chest open for the first time. Sometimes just having the proper tools make all the difference in the world. There is no need to overextend when you have "personal prop" assistance to help guide you into a great stretch with confidence and safety.
