Using a soft trapeze, Aerial Yoga combines basic yoga postures with the miracles of gravity. The result is a new practice that encourages proper alignment by strengthening shoulder and core ab muscles and increasing shoulder and spinal flexibilityâall without strain or pain. Like partner yoga or any other type of assist, the hammock-like aerial apparatus counteracts the affects of gravity, which is a great way to relieve compression and elongate your spine. Developed by Michelle Dortignac, a dancer and yoga instructor, she's been teaching weekly classes since January 2006 at S.L.A.M. in Williamsburg, Brooklyn. Other similar programs are popping up elsewhere throughout the country.
