Vskin Active My favorite DVD using the twins is termed Bellydance Core Conditioning; and the way to some very sexy moves, work your abs at the same time get some light weight work all the while following the twins. Since they tools you will need are a mat and some hand weights--and a willingness to try something completely new. Fun and a nice change of pace from the typical cardio workout-I highly recommend it!
