So many yoga classes teach this pose differently. Many use this as rest instead of child’s pose. Until I came to Washington, everyone in New York teaches down dog just as a flow, not as a rest.
I really like the flow from down dog to chaturanga, to cobra and then back. If you go to a great yoga studio, the experience is so much different than say the YMCA or another place that does not specialize in yoga. I recommend trying a studio that their main focus is yoga.
Yoga Shala ia a great company.
