Hello. Welcome back to another edition of the Keep Going podcast. In this episode we dive into what we have craft-fully termed the Four Systems of the Apocalypse.  The four horseman are: 

1. The Musculoskeletal System: The tendons, ligaments & bones; how they act, react function & coordinate
2. The Cardiovascular System: The heart & lungs & the role they play in getting oxygen & blood to where they need to be
3. The Metabolic System: aka energy systems, or how the body is fired & fueled for endurance
4. The Nervous System: The brain, spinal column, peripheral nerves or "The Mind".

John & I give a rough breakdown of each system, what it's doing & why it's important. 
I have to say, this was a tough episode to prep for & execute. There is so much to cover & we thought we'd be able to do it 30-45 minutes...boy howdy were we wrong. What you have here should be considered a primer, not a textbook. & we really try to target the functionality, the practical, real-life ways these systems impact the act & art of running. 
So I'll cut to the chase. Please enjoy this second episode in The Systems series we call The Four Systems of the Apocalypse. We hope you enjoy. 
Godspeed my friends, godspeed.
