It's great. Really targets those areas we don't often think about. It's bit like the toning part of BodyVive... but on steroids.

It's an awesome class, just please be careful with demonstrating proper form. I've definitely seen it not happen before and then the participants start mirroring this behavior.

An example being not stepping far enough or landing on your heel for side lunges, power skaters & wood-chops. That is how blown-out knees happen, especially for those who aren't that physically fit.

Also try to demo low options as soon as possible. I've had instructors wait until we got to the second side to demo the low option for a side-hover. Watching people struggle to do them on their feet and then just giving up completely made me sad.

i really love working on my abs so i find it the perfect class for me however i do think that the instructors who take it at my gym don't always tell you where you should feel it. For example the plank ans crunches are obvious but the weighted sections/ moves i can't always tell where i'm supposed to feel that. but i do love it pretty much love all the les mills stuff! xo

Be prepared and ensure your timing is spot on. Last week I went to a class with a new to my gym instructor (not sure how long she has been a group fitness instructor) and her timing was awful. Seriously, it was very bad. I was surprised that she could pass the training. What makes it even worse is her timing was off in tracks with a very heavy beat, electronic/dubste-like music. How can you not keep a beat with that kind of music?

Good luck!
