I love the upper body work in S&H, but don't use the lower body (I prefer other lower-body workouts like PLB, and those slo-mo lunges did not appeal to my knees!). As others have said, it's not at all like any other Cathe workout.
The slow count (6 up, 2 down) gives you the time to really play around with variations (doing a 3 down/5 up--which I usually prefer--or a 5 down/3 up, or a 4 down/4 up --which I prefer for the shoulder exercises).
IMO, S&H is the only Cathe workout that has a long enough rest period between sets to really increase strength (unless, like me, you put your own rests in the other workouts!).
As Lori Ann stated, there are those who find S&H boring, but I don't at all. (I like lifting heavy, and the slow work is almost meditative for me...though I certainly would be bored with a "super slow" workout with 10 reps up and 10 reps down!).
