I think you have to exert yourself for more than 30 seconds for anything to count as exercise, so in your case, no.

I don't think counts unless you do it standing up.
As for were you thinking of this: BBC News - Can three minutes of exercise a week help make you fit?

Ahhh. High Intensity Training (HIT)

But to really get fit in 3 minutes though you need Special High Intensity Training.
