I have her first 3 offerings.....and like her as an instructor. I think she's a good addition to the other advanced instructors like Amy Bento. She's professional and not annoying. However, with both Amy and Tracey....I have a very difficult time learning their step. The way they teach is just not good for me. They don't break down and all and they use really complex moves. The only complex step I can learn is Seasun or Rebecca Small, as she uses the layering system.
That being said - I still am able to get a great cardio workout (step) with Amy and Tracey. I've gotten myself used to doing my own version of the step they are doing, or a lot of times I can follow, but I'm never on the correct leg or side of the step....but I don't fuss too much about it as long as my HR is up. The intervals in Tracey's step are athletic and easy to pick up. I think her interval offering is slightly less intense than Cathe's....but I can always make it harder if I want. I don't think her impact is quite as high as Cathe's Imax's.
As far as her initial scuplting....it was just so/so in my book. It is more functional fitness based and I only do FF every so often if I decide to do a FF/Recovery type of week.
Her last Kickbox is fun and easy to learn....but I think it lacks a bit of intensity. I usually add some jumps and other intensity to it to make it a better workout.
She filmed her first series in one day and received a great deal of constructive critisicm from her customers and she is very attentive to what we want and I'm sure the new offerings will be much better, as she corrected all of the problems with the first ones and like Amy Bento, made her new series 90 Minutes each for a good price!
I think her forte is working the Core. Her Core DVD is excellent. I usually never do the entire thing at once (but it's doable) cuz I usually do it in 10-15 segments. She uses a lot of very unique moves and a lot of isometric holds which always seem to get my abs sore when NOTHING else does any more....not even Cathe...using weights! So, I think that says a lot for the uniqueness and effectiveness of her core work.
