Career

Kai Greene began his competitive journey in his teens, training at Johnny Lats Gym in New York under coach Jakob Panotas.

He won the 1994 NGA American Nationals at 19, earning his pro card, and later secured the 1999 NPC Team Universe title, though he took a five-year hiatus before re-emerging to win the 2004 NPC Team Universe, qualifying for the IFBB.

His breakthrough came with the 2007 Shawn Ray Colorado Pro/Am Classic victory, followed by first-place wins at the 2008 New York Pro, 2009 and 2010 Australian Pro Grand Prix, and the 2009, 2010, and 2016 Arnold Classic titles.

Greene placed second at the Mr. Olympia in 2012, 2013, and 2014, behind Phil Heath, with their rivalry culminating in a notable onstage confrontation in 2014.

Beyond bodybuilding, Greene starred in documentaries like Overkill (2010), Redemption (2010), Generation Iron (2013), and Kai (2022), which chronicled his life and career.

As an actor, he played Funshine in Stranger Things (2017), a male stripper in College Debts (2015), and roles in Crazy Fist (2018) and Pogaru (2021).

An accomplished artist, he creates self-portraits to refine his physique and exhibited his artwork in 2011.

Greene launched Dynamik Muscle in 2015 and the 5P training program in 2016, named after his motto, “Proper Preparation Prevents Poor Performance.”

He hosted the Generation Iron podcast (2015) and his own Getting It Done podcast (2020–present).
