First of all, I love the guy walking by. He seems to be completely unfazed by the trio, as if he sees people tethered to a park bench all the time. (Only in New York City, I suppose.) I really wish I could have witnessed this myself. It could be the next great workout! Or maybe it already is. Regardless, I wonder what they're doing. Clearly they like to resistance train, and I can imagine them doing a series of short sprints. Maybe even walking lunges. Or jumps.
Tell me, what do you think they're doing?
