Author, fighter and family man Mark Tullius (pictured sparring above) first appeared on this site a few weeks ago in the article "Endurance Sports, MMA and Extreme Exercise – Are They Worth the Risks?"

Mark describes himself like this:

"I'm a father and a husband, a brother and a son. I'm an Ivy League grad who worked in a warehouse, an MMA fighter with too many defeats. I'm the bouncer and bodyguard, the drunk guy in the fight. The jailer and the jailed, the guilty and innocent.

I'm a writer shaped by influences, too many to count. I grew up on King and Koontz while force-fed the Bible. I narrate Dr. Seuss and Disney nearly every night. Like you, I've seen things I wished I hadn't, heard some truths I won't forget.

Writing is my heavy bag, the sparring partner that doesn't punch back. It's where I shed my armor and cast off the blindfold, take a look at myself and the world around me. The writing takes me wherever it wants. Dark alley or dinner table, classroom or morgue. I go along for the ride and try to capture the moment, show life like it is and let you be the judge."

Today, we're going to take a deep dive with Mark into unlocking the psyche of competitive sports, head and other injuries, testosterone and testosterone replacement therapy (TRT), Performance Enhancing Drugs (PED's) in MMA and other sports, the best training programs to turn yourself into an absolute beast and much more.
