Regular physical activity is an important condition for maintaining a good health: a little more intense exercises further improve the situation.
Half an hour of moderate physical activity at least five times a week: the
recommendation is well known and its benefits have been widely demonstrated. This Australian study indicated that (James Cook University) is that the integration or supplement to more intensive exercise gives even better results. It does not take much. Fifteen minutes from these, ten minutes there: as long as the effort will lead to a slight breathlessness and sweating a little, this translates into a very positive effect.
This was demonstrated when monitoring for ten years of some 200,000 people over 45 years. Regardless of age, gender, body mass index (BMI), presence or absence of cardiovascular disease or diabetes ... the practice of intense physical activity sequences further reduces the risk of premature death compared with only moderate intensity exercise (already very beneficial, insist on it).
The board, for example, is to "push" the effort at intervals, eg current or strongly accelerating not for two or three minutes, several times during a walk in a half hour to an already strong pace.
