Similar to the Yoga Block, the Yoga Belt is often used in Pilates classes in order to make you more comfortable and to enable you to perform exercises with correct form and alignment. The Belt focuses on enabling you to perform stretches correctly and without strain to other body parts- neck and shoulders in particular. The Belts can help achieve certain positions, extend and lengthen your reach in different positions such as reaching your feet or holding your hands behind you back (e.g Double leg kick).
Yoga Belts can also be used to replace the Elastic Band in the more static stretches or when we do not need the elastic quality of the band. If you don't have one and you can try to use your bathrobe belt as long as it is sturdy enough.
