Jillian Michaels' 30 Day Shred is an awesome workout that will begin showing a difference in your body in about 5 days, and put you that much closer to a body like the super toned, super hot Jillian Michaels. This workout operates under the principle of muscle confusion, which means your development will not plateau, and you will see results fast. Muscles get accustomed to repetitive work-outs very quickly. Most people do not know this is happening, continue the ineffective work-out, and then get discouraged at the lack of progress. Work-outs like the 30 Day Shred use muscle confusion to tone and slim your body quickly and efficiently, and the end result is undeniably amazing.

1.Before you start Jillian Michaels' 30 Day Shred, take your measurements. You'll be glad you did later. Measure each arm (thickest part), each thigh (thickest part), upper waist (smallest) and lower waist (at your belly button), and your hips (biggest part). Write this info down, or put it in Excel so you can come back to it after 30 days. This work-out will probably cause you to lose weight, about 10 lbs, but that can vary. You will definitely lose inches, however, and develop tone that will surprise you. The reason your weight doesn't drop as quickly is because you are developing muscle and reshaping your body.

3.Set aside a time of about 30 minutes each day to do Jillian Michaels' 30 Day Shred workout. You really need to do the program EVERY SINGLE DAY for results. It's very difficult in the beginning because you will be so sore, it will hurt to live. Jillian says work through the pain. Do not stop or wait until the soreness subsides, and you will be amazed at the change in your body in just a week.

4.Start with 3 lb. dumbbells and work up to 5, or start with 5 if you think you can handle it. Jillian Michaels and the other fitness instructors are using 5 lb. weights in the video, but they are advanced trainers.

5.Jillian Michaels' 30 Day Shred is designed in three levels to be done over the course of 30 days. Level 1 of the workout should be done for 10 days, Level 2 for 10, and Level 3 for 10. When you finally can complete Level 3 of this fitness program, stay there, or mix it up every once in a while. When I started Level 1, the first three days, I could not do everything. I had to severely modify it by using the weights only half the time each set (the other half I did without any weights at all), and doing female push-ups. On about Day 10, I could almost do the whole thing. Feel free to stay on Level 1 until you can master it, then move to Level 2. You do not have to move up every 10 days

6.At the end of 30 days, take your measurements again, even if you are only on Level 2. You are sure to see a change of about 1 to 2 inches in most parts of your body. This will probably put you down a dress/pant size. In addition, you will be stronger, more toned, and actually in shape. You'll be glad you let Jillian Michaels kick your butt.
