The average person sits for more than 6-8 hours. While we can't avoid sitting (and sometimes it's necessary), most of us do too much and continuous sitting can increase your risk for disases such as diabetes, heart disease, cancer and dementia, and early death. In this episode we discuss the problems with sitting, how it affects your metabolism, can your exercise counteract sitting and provide you with tips on how to reduce your sitting.
