I keep on seeing this core rhythms dance exercise DVD workout advertisement on TV. Sometimes advertising can be exaggerated and product results are not met but the public in general are the advertisers' target. That is why most advertisements are making sure they have the right concept that will appeal to the masses and persuade them to buy. Well, I was convinced so to speak with this DVD so I ordered online. The package contains 4 DVDs and each has diffrent workout rhythms. I have tried it a few times. I hope this works but it goes with dieting of course. Core Rhythms is an exercise workout that uses sexy Latin dance actions to raise the heart rate. It tones and tighten the upper abs, middle abs, lower abs, obliques and your back. It's really fun and you will be sweating a lot!
