In my never ending quest to lose weight I have discovered a great workout that is less than 30 minutes. It is Jillian Michael's 30 day shred. There are 3 different workouts, 3 different levels. I have been doing them for several months now and I wish I could say that I've lost weight but I have not. However, my body is changing and many people have said they have noticed that I'm losing weight, so that's good. The workouts consist of a brief warm up, 3 circuits of 3 minutes of strength training, 2 minutes of cardio and 1 minute of abs and then a cool down stretch. It's a tough workout but if you can hang in there for about 24 minutes or so then you're done!
