Powerstrike
I have two Powerstrike workouts... One of them is Powerstrike 5; the other is just called Powerstrike. I don't know if there are Powerstrikes... but you can see these two on Collage Video.com
I know what you mean about doing all on one side, then a different routine on the other side (though she says you're doing the same number of kicks and punches), then the third routine switches back and forth. But I do like the workouts and I also like the fact that there is no jumping. Sometimes my legs just need a break, but I still get my heart rate up.
She has a couple of other videos -- a push-up/ab video that I find very challenging, and another one that focuses on legs -- also challenging.
I like Ilaria's style, though it took a bit to get used to her accent. She's very precise about form.
Hope this helps.
