We are built to move
On a cellular level, motion controls our systems. Exercise and your cells get stronger. Sit and your cells decay. It’s that simple.
This is a big deal when you realize that your body is made up of trillions of cells. Most of these cells live for a few weeks or months, and then are replaced by new cells in an endless cycle. Your whole body (apart from a few stem cells and brain cells) is brand new every three months.
You get to choose whether these new cells come in strong or weak. When you exercise your muscles release substances that travel throughout your bloodstream telling your cells to grow. Sedentary muscles send out a steady trickle of chemicals that tell your cells to decay since they aren’t being used.
True biological aging is a slow and graceful process. No one wants to live in and old, achy body. But you can live your whole life in a powerful, healthy body when you are willing to put forth the effort and keep moving!
