I love the Jillian Michaels Ripped in 30 workout. I have tried almost all of Jillians workout DVD's and this one is one of my favorites. Being able to get a good workout in, in the comfort of your own home is great! Personally, I get self-conscious working out in front of other people so this is perfect for me! Like a lot of Jillians workout DVD's this one has different levels that you progress through. There are 4 levels that are a little under 25 minutes each. She combines strength training and cardio for maximum results. You WILL see results if you stick to the workout plan. The workouts are hard. You will sweat. You will probably be sore the following day until you get accustomed to the workouts. Jillian is an awesome instructor and she's very motivating throughout the videos. Overall, I highly recommend the Jillian Michaels Ripped in 30 DVD. It can be done at home in under 25 minutes and you will see results if you stick with it!
