"The research team hopes it will improve the health of the nation by making it easier for everyone to find time to exercise. "
Oh dear. The problem is that it is difficult to figure out how one can fit this sort of exercise into normal life without going to the gym, time consuming in itself. Anyone fancy going to the shops in the form of 30 second sprints with 1 min rest in between? Thought not.
The article mentions running up stairs which would work but not everyone has access to a 30 second flight of stairs (having to perform accasional stair runs in my job, this is quite a lot of stairs) And quite frankly, even if they do have access, who is actually going to do it? And if they do do it, who is actually going to do this at the kind of intensity needed?
Nice idea but it is not going to work for the same reason that no other form of exercise regime works. People are lazy.
