Query: Horrible form...look elsewhere.

She may be popular, but that doesn't mean she knows what she's talking about. Her form is horrible and the only way she gets away with it is that the weight is so small. I've been studying kettlebell technique from specialists for the past two months and her form is dangerous. I recommend checking out the books by Pavel Tsautsouline (Enter the Kettlebell, for instance) instead. Youtube the keywords "jillian michaels kettlebell response" to find some informed views on her teaching.
