does this work? i know JM gets a lot of respect on here, so ive been thinking about trying it. im a little confused about the program tho, is it 3 20 minute workouts per day? do you do them all in a row? is it recommended for people who are beginners? is it really "30 days", or do you have to keep doing it permanently to keep the weight off? is there a special diet to follow?
the "up to 20 lbs" claims are making me skeptical..
