Just in case this blog hadn't provided you with enough reasons to get up and move yet, now we present to you your lymphatic system.
What in the world is that?
Well, you know all about your circulatory system, right? Heart pumps blood through your body, carries oxygen and nutrients to all your cells?
See, there's another system in your body that's sort of like that, that carries a clear fluid called lymph all through your body. Lymph helps remove unwanted stuff that's hanging out inside your body, and is an important part of the immune system. Lymph isn't something a lot of people know they have, but it's important to staying healthy.
Lymph has a disadvantage compared to blood, though--there's no heart for the lymphatic system. The heart will keep the blood moving around no matter if you're lying down, running around, or sitting on the couch watching Dr. Phil. There's nothing that keeps the lymph moving, unless you move.
Any movement helps--just taking a few deep breaths can get it flowing, although some people recommend sharp, quick breaths--but as you've probably guessed, nothing gets your lymph flowing and flushing out your system like exercise.
So, not only will exercise bring down your weight, help your heart, and release endorphins, but it will also help prevent sickness and cancer.
