It differs from the old Surgeon-General's Report in that it makes it clear that the 30 minutes of moderate activity five times a day is, in a sense, a minimum, and that, by and large, more is better. In fact, many of the examples they give have a target of an hour five times a week. They also come out explicitly and say that one minute of vigorous activity is equivalent to two minutes of moderate activity.
Also interesting is that they state clearly that muscle-strengthening activities should be part of any program. Unfortunately they say essentially nothing about how to set a muscle-strengthening program.
A good read for those interested.
