This is the worst thing you're doing to your body, Libra...
If you, like many, spend your workday at a desk, you're in danger of suffering more than just a midafternoon slump.
When you sit for a long time, the disks in your spine get unevenly squished and lose their healthy sponginess. Collagen hardens around the supporting tendons and ligament, and that's when you get a stiff back. Ouch!
Good thing the solution is fairly simple. When you get up and move, you immediately boost your thinking skills, which will help you be more productive for the rest of the day.
And moving helps the soft disks in your spine expand, contract, and soak up fresh blood and nutrients like little sponges. Whether it's a workout or walk, give your brain and spine a boost!
