Query: I Didn't believe it could work this well, this fast

I've watched the infomercials several times, but still never made the commitment. I have a gym membership but with my work schedule, I needed something to help me be more consistent and help me BURN calories. I love cardiokickboxing, I love to dance, I love music. This tape has it all and BONUS, it has sculpting/weight lifting. I HATE lifting weights because for me it was boring. I did the Learn and Burn then explored the other workouts on the DVD. A few minutes into the Sculpt portion, I picked up my hand weights and joined in. I was lifting weight, but I was still sweating majorly! She has good instruction throughout and is very encouraging. I felt good! I felt energized! Even with limited sleep and after a long work day. Then, I checked myself out in the mirror and I can already see my abs starting to get more definition!! My worst area and I've NEVER had any definition. I can't wait to see how I change after weeks of working out and sculpting.
