This is just one product I've seen of this type - it combines cardio w/weights and using your own body as resistance - I think it works wonders! Try taking your measurements - neck, upper arms, wrists, chest, bust, waist, hips, thighs, calves, and ankles - then you won't have to rely solely on the scale to see what's happening to your body!

I love jellybeans, too! But my vice is that I live right next to the Ben and Jerry's corporate office/scoop shop/and the mother of all ice-cream factories! AAAAAAAAAGH!
