It is important to take frequent breaks during your workday and to avoid sitting for more than 1 hour at a time. In the course of a workday you should take a mini-exercise break for 1 to 2 minutes once an hour. Take longer breaks of 3 to 5 minutes once every 2 to 3 hours.

These exercises can help you feel less tired and lower your risk of overuse injuries. They can be done during short or long breaks.
