Not trying to put you down or anything, but oh my gad, I actually did it faster than somebody! It was still pretty slow, though. Like I said, I can't run.
EDIT: That being said, we had two Army recruters come into our gym class today. I thought they we're doing some sort of "advertisment, promotion, Join the army" type thing, but they ended up having us do a series of workouts. They had different stations set up around the gym consisting of burpies, frog kicks, push ups, wide arm push ups, jumping jacks, etc. We had to do two laps of the gym. 30 seconds of the excercise, jog to the next station, jog in place until they told us to do the excercise.
I don't know how, but somehow I made it through the whole thing. Quite a workout, and I couldn't feel my legs or arms for about the next hour. I don't think I've ever exercised that much or hard in one go.
