Did this workout this afternoon. It was fun with pretty uncomplicated moves and very minimal high-impact (which you can always choose to modify). The music was cute - not quite the heavier EDM that I prefer in my workouts, but those who don't care for that kind of music might find this one's soundtrack pleasant and peppy.
As far as intensity goes, this really didn't hit the mark for me. I don't consider myself a honed athlete by any means - there are workouts of Cathe's that are so intense they tend to gather lots of dust on them before I do them again. For comparison's sake, workouts I find to be edging on "never again" are ones like Strong & Sweaty's Cardio Slam, or Intensity (the one with the black and yellow workout outfits).
This did get my heart rate up, and it kept it in a general steady-state cardio zone. Just didn't have quite the oomph I'm used to with most of Cathe's cardio. If I were to compare this to any other cardio, I'd say it's kinda like LITE Cardio Party, only less intense. I can see myself using this workout on days when I need a bit of a break.
I also chose to do the workout without the band marker as I worry it'll be come a tripping hazard for me. Maybe I need to bring it out as its presence may get me to subconsciously lift my feet higher which would maybe result in a bit more intensity. I wonder, too, if I might bring out my step for the last portion where she turns the band horizontal to mimic a step. I know that would increase the intensity a bit, too.
One final note, and I'm curious to see if others who've received the DVDs notice this, but the picture quality seemed almost low-res. Not horribly pixelated or anything, but Cathe didn't look as crisp as I usually see in her other workouts, like in STS 2. And Lisa and Nicole were borderline blurry when viewed from the front-facing camera angle.
I tried fudging around a bit with my TV's picture settings to see if maybe something was wonky there, but really couldn't get much improvement.
It didn't make the workout impossible to do, but I had to get past the feeling like I needed my glasses for a bit.
