According to the CDC, "People who are physically active live longer and have lower risks for heart disease, stroke, type 2 diabetes, depression, and some cancers."  This includes our public health recommendation of 150 minutes per week of moderate-to-vigorous activity. However, in the past decade, more research is showing that people are getting too little exercise and doing too much sitting.
Research shows that taking more standing breaks during the day is associated with smaller waist size and lower body-mass index, triglycerides (fat in blood), and 2-hour plasma glucose (blood sugar). For better or worse, this is regardless of whether you work out! 
Here are simple things you can start today to get more active:
1. Stand at least 2 minutes every half hour (use a sit-stand desk)
2. Take 250 steps per hour- walking in place counts
3. Use the second nearest restroom and water fountain from your desk
