I've done Build 1 and Burn 1 so far (and am about to do Sculpt 1--if I can ever tear myself from the computer this morning
) and I really love these workouts. They were exactly what I expected in terms of intensity, production quality, and enjoyment factor, so I think that's why I wasn't disappointed when I previewed them, and eventually did them.
I think there is something about these types of circuit workouts (ones that are entirely built on strength exercises, vs. ones that mix cardio exercises with strength ones) that click with me. And something about Valerie's choice of exercises and sequencing works for me and makes it fun. I not only get the results, but I have fun as well (which is probably why I get the results--because I am consistent about doing them and there's no dread factor).
I also feel that for years I was trying to push myself with advanced workouts, thinking the more intense, the heavier, etc., the better. But in reality, moderate workouts with moderate weights is what works better for me--and more importantly, what I like. So when I finally gave up the idea that I have to do something like STS or else I'm just wasting my time, when I gave myself "permission" to do lighter weights that still challenged me, that's when I started seeing and feeling results.
I'm definitely happy with my purchase!
