Is this a good workout routine ?? GOAL: Flat/Toned Belly! HELP!!! (10 points)!?

I swear by Yoga. Yoga Sculpt (you can watch it free on OnDemand or at exercisetv.tv) is amazing. Its meant to sculpt your body. I did it last night (I did it every day for a couple fo weeks and saw a huge difference in arms and overall my body then I had to go to school and now I am doing it again) and I was sweating and it feels amazing.
