Query: Debbie Rocker rocks!

Finally - a workout that really changes you- or rather - a workout that finally made changes in me- not just weight loss- strengthening! I can jog now for short blasts - which is so empowering I keep returning to this workout. Thank you Debbie Rocker! I alternate the Rocker DVDs with Leslie Sansone's WalkAtHome dvds. start the day with a little sweat!
