2. Set a timer

2. Set a timer. For those who don't have a treadmill desk or a standing desk, make it a point to stand up and walk around at least once every hour. Studies have shown that sitting for long periods may decrease your metabolism, hurt your heart health and even increase your risk of cancer. One easy way to sit less is to set an automatic timer on your computer or phone to alert you once every hour. As soon as you hear that alarm, stand up and get moving for a couple of minutes. You can do jumping jacks, walk the stairs in your home, stretch, do some yoga poses, take the dog outside—whatever you like to do. Just move! Making it a priority to get up and move once an hour will help your health and your weight-management efforts, and it'll even give you a mental and emotional boost to help you get more done.
