So I was the gym today ...

It sounds funny to say that, considering that until a few days ago I had never considered the possibility of joining a gym. But today I did my little round of exercises that Toni, my trainer, gave me (ok, so she was my trainer for only an hour orientation, but it just sounds good to say it) and I feel pretty good.

But I have a question: what did people do for exercise before the creation of fitness clubs? I mean, how did the pioneers get their cardio training without treadmills? How did the pilgrims become strong enough to do all of that physical labor in the new world without the availability of nautilus equipment?
