  • Fun Fact
I prefer backwards dinners that start with dessert. Thankfully, CFX and HK Power Flow work off all that sugar!


Heidi is the best yoga teacher in NYC. She is warm, approachable, STRONG and lovely to be around. Her positive energy makes everyone in the class shine.

Heidi has the strength of a thousand men... when you first see her, you may think she's a petite run-of-the-mill yoga instructor. But then you see the images of her doing the various inversions she's known for, and doing regular articles for Shape magazine, and leading all the.. inversion workshops, and your mind is completely blown. In short: I'll definitely be back for some butt-kicking, high-energy yoga!

What a goofball. Heidi's big personality made the class. She is this tiny gorgeous girl, so it was kind of a surprise. But you know what they say, big things comes in little packages! I enjoyed myself because she was just so fun!
