Well, now that you're telling us about it you would have no choice but to create a circuit and try it out!
Absolutely. This is an awesome idea.
Good for you for setting this up and using it! A very clever idea.
I kind of did that once in our yard. Did some exercises on the front porch, ran around the house and up the stairs to the upper deck, and did more exercises there. I think it was stuff like step-ups in front and jump rope in the back, nothing using the natural (non-existent) features of the yard.
Great idea. I may have to resurrect my circuit.
