I'm glad you brought this up. I saw my first commercial last night for EA Sports Active (not sure if it's new, or if I just haven't been watching the right channels where it's advertised)...but it seemed interesting.
Like you said...it is certainly not the intensity of P90x...and being a marathon runner myself...I guessing that it's not that intensity either. When I first saw it advertised last night...I thought that it was for a "virtual workout" with "virtual workout humans" that you hooked this program up to a treadmill or stationary bike (which I thought would be REALLY cool)...but then realized that there might be interface problems...and that it is actually designed to be used with gaming console's.
Kind of cool that it has a HR monitor. I use an HR monitor when I train/run/race...and find it very useful to track HR during a workout, and from a historical perspective as you get more fit.
It sounds like this product is certainly better than no workout at all (and could be fun as well)...but that it may not be a substitute for a "traditional workout"...such as weight-lifting, running, cycling, swimming, etc.
I'm interested to hear what other folks have to say about this from a workout & fun perspective...which may help me decide whether to buy it for my PS3 or Wii.
