Query: Cindy Crawford - Next Challenge Workout

I have done this DVD 3 times a week for the past 3 weeks and can see a distinct change in my body shape with definition really improving. I've not 'bulked out' but can see a trimming of my body shape to a more althletic appearance which is great.It is hard work and you definately know you've worked out but it gets the oxygen circulating and you feel a lot more alert afterwards.Happy workouts!
