can sex count as my cardio?

i believe the average is 400-600 calories for 30 min?? dont quote me of course lol
 
And you can do HIIT all by yourself! GTG. :-)

Wait, I think I feel an innuendo in there somewhere.... :angel2:




On a serious note: If taking matters into one's own hands were to be done in true HIIT fashion; I can imagine some folks would be making trips to the ER with some strange cases of burns or chafing in regions one normally wouldn't see that kind of injury in. :laugh:
