Query: A product that grows with you.

the dvd was better than i expected. i found it to be a good alternative to a treadmill for those of us who find that boring and to exercising outside when the weather does not permit. it was not as strenuous as other work-out videos can be but i found it to be quite effective and to do what it is meant for,"walk away the pounds." it's like my early morning or afternoon works, simple but effective and you feel you've really accomplished something without breaking your back. i highly recommend it. the good thing about this series is that when you have reached your fitness peak for this video you can simply move on and buy more miles.it's a product that grows with you and your fitness level.
