Today, we’re going to dig into why exercise helps you live longer. Endurance running is in our genes. It’s a survival mechanism. Over time, our genes have adapted to anything that increases our survival. When you exercise, a lot of good things happen. 

The leading cause of death is cardiovascular disease. So, anything done to improve cardiovascular health would help extend your life.  An interesting study actually compared people who did physical activity vs. inactivity.

They found that the group that did physical activity decreased their mortality by 30-40%, adding an additional five years to their life. 

Why exercise helps increase lifespan:

• Increased O2 (blood flow)

• Decreased inflammation 

• Increased parasympathetics 

• Decreased insulin resistance 

• Increased growth hormone
