CNN  — 

You’ve been chained to your desk working remotely day in and day out. Schedule this mini break in the middle of the day and call it a meeting!

You’ve probably heard by now that sitting has been called the new smoking. With negative health effects from long-term sitting such as increased blood pressure, increased risk for obesity, high blood sugar and even cancer, too much sitting has become a cause for concern for people everywhere. In fact, research has shown that increased sitting time is linked to a higher risk of death from all causes.

Couple that with the fact that people are working from home with fewer walks to and from the copy machine, bathroom and conference rooms plus no commute time/ Our bodies can become even more sedentary as a result of the pandemic and working from home.

Even if you start your day off with a workout or our five-minute morning yoga routine, after hours of sitting your body is more than ready for a break. Not only does taking a break from sitting help improve circulation, but it also helps improve joint mobility. Joint mobility exercises lubricate the joints and help you feel warm and limber. Working on joint mobility is also great for older adults with arthritis or joint pain.

This five-minute midday workout is designed to get you up out of your chair and use it to improve mobility, get your heart rate up and stretch out your entire body.

For this workout routine, you’ll only need your desk chair as a prop.
