She's a friend of Jillian's and a fitness demonstrator.

Her fitness DVD from 2007 of circuit training

She is also in Killer Buns and Thighs and Body Revolution. All from Jillian Michaels! I wonder if she is on Twitter though?

Brutal workout, but helps burn calories with the circuit training and its cardio-nature.

"Jilian Michaels has 8 dvd's available for order. The titles are as follows; Killer Buns and Thighs, Ripped in 30 Days, 6 Week Six-Pack, Shred it With Weights, Yoga Meltdown, 30 Day Shred, No More Trouble Zones, and Banish Fat Boost Metabolism."
