conditioning is evident by the last 20 seconds of the workout tape. He was winded laying on that floor. The stuff he was doing looked "silly" but if it taxed his cardio it helped him.
He didnt need to build strength but it probably went up because he only did one heavy day a week. He probably recovered better.
I really liked that one exercise he did about a minute into the tape. I dont know what you call it but theres weights on a straight bar and hes picking it up off the ground.
