       | it too seriously.

       | This study is just bringing down the 20 seconds to 4 seconds, as
       | per the article,
       | 
       | The increased rest time means a longer work out.

         | 
         | Or at least 4x 15sec if you are in terrible shape.
         | 
         | Also, what are the units of "fitness" that increase 10%? That
         | smells fake.
         | 
         | The article doesn't mention a control, either. Talking to a
         | doctor might be enough to motivate increased activity (and
         | better eating), regardless of the minute of activity during the
         | meeting.
