I have Powerstrike Millenium 1 and 2 and I love them both. I have to say, the production values are awful, the sound quality and picture quality are pretty poor, but these are probably the best kickboxing workouts I've done.
They're quite different from Cathe's kickboxing. The basic set-up is warm up, punching drills on the left side, two different combos on left and right sides, then the punching drills on the right side, followed by one more section (in 1 it's jacks and front kicks and in 2 it's blocks), then a cool-down. There is no "cardio" section, but you really sweat with these. And they're the only kb workouts that give me DOMS in my lats
The instructors are also very good.
I'm sure many other Powerstrike lovers (and there are lots of us) can chime in too!
Went to Powerstrike's website last night, Millenium 3 is released although the website that offers it doesn't have *any* of Millenium 1, 2, or 3. It says that they are "temporarily out of stock" on all of them.
