Query: Amazon Prime: Where 80s exercise videos go to die

This has to be one of our culture's first stabs at taking over yoga and marketing it in the USA. There is no vinyasa AT ALL in the first thirty minutes. The poses are so short and stilted and out of context, it's hard to think they give much benefit. In the second half, she tries to get people to break a sweat by adding weights to a lil bit o' flow. Videos like this make me so grateful for all the dedicated yogis who have traveled to India to learn the practice and bring it back in its original form.
