I recently attended Bryan Kest's workshop (10th Jan) and was a little disappointed that it was exactly the same workshop that I attended last year, word for word. I still really enjoyed his power yoga, but would of loved to of heard another point of view from him.
And both times I have been to his workshop, they have ran over by 20 mins. I would assume that it would be better marketing the workshop as 3hr and 30 mins. I live over 30 mins away from the studio and have had to hire a babysitter to attend. It is an extra cost to factor.
