I didn't use Power Hour but I used the PS series with the BodySculpt series and got some pretty good results.
Here's what I did:
Mon
PS-CST
Firm BodySculpt
Firm Abs
Tues
PS BBA
Firm CardioSculpt
Wed
PS Legs & Abs
Thurs
PS CST
Firm BodySculpt
Firm Abs
Fri
PS BBA
Firm CardioSculpt
Sat
rest
Sun
rest
I did this for three weeks and lost an inch on my waist, 1 1/4 inches off my hips and 1/2 inch off each thigh, 1/2 inch off each arm.
I get bored pretty quickly, so sometimes I swtiched the Firm's SuperSculpting or their Tough Tape 1 for Body Sculpt.
