In 2020, many people started working remotely and more purchasing was made on line. As a consequence, they spent a lot more time sitting.

Bouts of physical activity counteract some of the negative effects of extra sitting, but how much is needed?

A meta-analysis compiled results from nine different studies on the topic and showed the average daily sedentary time ranged from 8.5 to 10.5 hours (not counting sleep), whereas the average daily moderate physical exercise time ranged from 8 to 35 minutes.

The results suggested that while higher sedentary time is associated with increased risk of death, the risk can be partially offset by 30-40 minutes of moderate-to-vigorous physical activity per day.

For those exercising regularly, you can experience ‘exercise resistance’ which means that your body is used to that length and intensity of activity.  In order to overcome this, you need to make changes to the length or intensity of activity to keep your metabolism fired up.  This might me a longer or faster walk, or incorporating more hills.
