The following infographic shows us why sitting is detrimental to our health. Some interesting facts include how often we actually sit (9.3 hours!), the affects of non-activity (decreased calorie burn, no muscle activity, etc), and how to overcome these potential issues. If you think about we sit all the time: for our meals, at work, while watching TV, in the car… basically everywhere, so its clear that the potential threats of constantly sitting need to be taken seriously.
In short, be more active!
