Gentle rocking dance step for balance or lullabyes

Move With Grace is a lovely spot to do yoga (and even have a healthy drink) in Brooklyn NY. They run a  special of two weeks for $45 for unlimited classes...Anyone lucky enough to live close enough to it to take advantage of that offer (given time and basic flexibility though there are many offerings and one can work at their own level which is true of many fitness programs) would be wise to jump right in (or get in shape a little at home, maybe using the Yoga By Candace site and app or her book Namaslay.
