I LOOOOVE skinny bitch total body dvd. it gives amazing results and is easy to do. it really works all muscle groups and provides a lean toned body. that being said, its not really difficult to do but you will feel the results and toning immediately and more and more each time. YOU WILL GET AMAZING RESULTS WITH THIS!! think lean ballet body! results i havan't achieved with any other fitnuess regimen!! I actually turn the volume down and put it on my portable tv and watch tv while im doing it. the "instructors" ( rory and the blonde chick) can be really really really annoying after awhile. sometimes reminding me a bit of paris hilton with the whole bitches talk and talking about being sweaty bitches..etc...thats why i turn the volume down! also they're not really instructors and it shows! they don't give very clear instructions and sometimes do it wrong themselves but after you've done it a few times you'll know what to do and you can turn the sound WAYYYY down like i do so you don't have to listen to them! so i ignore the fact that they are really annoying bc i turn it down anyways and focus on the benefits which is amazing results. if you do the video 3-4 a week mix in one day of cardio and you will have a fantastic smokn hot yoga/pilates/ballet dancer body!!!! this is def worth it! buy it for yourself, your sisters, your mom, your girlfriends..awesome find!! (i got better results with this then the tony horton (10 min trainer, P90x systems...etc) because its easy to do and kinda fun the routine is fun and you can see your muscles being sculpted with each workout..the more times you do it the more you will want to do it more because the results from each session are visible and defined :) hope that helps!!!
