I suppose you could say that if we're talking about the big picture lol. It was hard for me. Not only in terms of muscle burn (I can't think of another term), but I swear it's a harder cardio workout than actual cardio. It makes my heart race. It's 100% necessary though, especially if I'm working on stability in the lower body and some (hopefully one day) explosiveness down there.Sucked in a good way?
