@feelslikebrick When I was rehabbing an ankle injury I had to pull my physical therapist around on a rolling chair in basically that exercise but they didn't have a sled in their office. Really should have gotten his weight!
@justin_holmes I can squat my wriggling 65 lb and growing puppy off the ground and into the car. Not that much weight in the grand scheme of things, but they're sometimes literally ass to grass squats and did I mention the wigging?
