I think she's bashing pilates because she isn't profiting from a slice of the reformer pie, and we all know all she cares about is money. She also doesn't have the typical pilates body - she's stocky and doesn't have abs and therefore doesn't fit in with what is seen as 'trendy' at the moment.
More and more people are waking up to the fact that ridic workouts like hers don't make you feel good. They give you injuries, and promote over exercising and bad form over working out for enjoyment etc. I always get the sense that she works out as a punishment for eating and I get that vibe from her workouts.
Pilates has transformed my life. Fair enough I don't see 'gains' like I did with weight training but I feel so much more better in myself.
