What is aerial yoga? Instead of performing yoga poses on a mat, aerial yoga utilizes a silk hammock that is suspended safely from the ceiling. The purpose of the hammock is to provide support through your yoga flow, while also improving flexibility and range of motion. The Sanskrit word for Aerial Yoga is VaihAyasa, which means moving or suspending in the air. VaihAyasa uses a soft fabric hammock that allows the student to deeply relax into proper alignment without strain to the joints. Using the fabric to assist with inversion allows the spine and neck to decompress. The weight of your body supported by the fabric creates space in the neck and spine. Stretching is easier and benefits the connective tissue, the fabric is a wonderful prop that allows deep stretching, strengthening and releasing.
