I have to agree, this is one hell of a workout. My little sister got it for Christmas, along with 2 foam pads, and I got a bit hooked. In a week i dropped 5 lbs like it was nothing on Standard mode on DDR Extreme 2. I had to velcro the foam pads to the floor so they didnt slide, but its working out really well. Now that I'm back to school, I use the workout facilities there, but this is actually a decent alternative.
