Anyone here play DDR?

[NERV]

Iuno about the rest of you but i love DDR, i got max 2 about a week ago, today i was playing it on heavy with 20 pounds of weight on my feet, i can still pull out A's with the weights, and then after about 30 minutes i notice that my legs were hurting like hell, but i didnt stop, i figure theres always a little bit of energy left, so i kept going for anothe rhalf hour until i just couldnt lift my legs anymore they were just sliding on the mat and i got a B, at that point i was done and i barely was to walk over to the computer chair to rest.

But back to the point, anyone else here play DDR, or is it too much physical ativity for the average macross fan?
