If you're looking for a high-intensity, quick DVD workout to tone muscles and burn calories, the Jillian Michaels 30 Day Shred provides three intensity levels to work your body. Skip the first level and move straight to Level 2 if you already work out regularly.
The "30 Day Shred" provides a high-intensity workout, incorporating strength training, abdominal toning exercises and cardiovascular exercise into short intervals. The Level 2 "30 Day Shred" also includes a brief warm-up and cool-down segment in the 20-minute workout.
Your starting weight and fitness level will impact how many calories you burn doing the Level 2 "30 Day Shred" workout. With a starting weight around 150 pounds, you can expect to burn approximately 503 calories an hour doing this DVD, or 167 calories for a 20-minute workout.
The "30 Day Shred" is an intense and challenging workout, even at lower difficulty levels. If you are new to exercise, you may want to start with the lowest intensity level rather than level two.
