Large health gains are seen in individuals increasing their activity levels from very low amounts. For instance, increasing from 10 to 20 minutes of moderate intensity activity per week has a significant effect on life expectancy even though individuals are below the recommended 150 minutes of moderate intensity. So, it’s worth supporting very inactive individuals to change their behaviour, particularly as many of the least active members of the population are often seen in healthcare settings.
