Hi! S&H is my favorite Cathe weight series! It is hard but I get the best results from it. It is a very slow count,for the most part 2 up, 6 down or vice versa. She has you stand at a slight angle so you eliminated any momentum that might be assisting you with the weights. It is all done with dumbells (the arms anyway). Its a very different feel though, sometimes I don't even sweat but BOY do you get a workout. You have to concentrate a lot and she only recommends you do them for short rotations, 3-4 weeks. I do S&H every few months and ALWAYS immediately feel a difference in my core region, and it always gets me through strength plateaus.
