This advice strikes me as so demanding as to be counter-productive

New health advice:

The new guidelines say:

· 30 minutes of moderate exercise a day is still the minimum, but vigorous as opposed to moderate activity should be "explicitly" recommended

· Combining days of moderate exercise with other days of vigorous exercise is better for you

· Moderate exercise should be in addition to daily activities such as casual walking, shopping or taking out the rubbish

· People should do two weight-training sessions a week

I would imagine that this would help dissuade many people from bothering to do even moderate exercise, since they'll reason that it's not enough.
