I agree. It IS weird going back to working out solo after taking live classes. It's a bit lonely and will take getting used to. Working out live has definitely changed the way I see Cathe/crew and the studio. In a cool way, though.
I think another way in which the live workouts differed is that she gave us small water breaks, which, of course, you can take at home by pausing the remote. It's just different doing them with everyone else. P90X includes water breaks in their footage and I like that.
I also think the live workouts were easier than her videos, probably because she realized most of us were running on fumes (herself included)!
