Who are these mysterious Buttery Bros of CrossFit, and where did they come from? We’re here to answer those questions.
The Buttery Bros Story



A mysterious YouTube channel popped up in January of 2019. The name? Buttery Bros. The content? Buttery.
Founded by documentarians Heber Cannon and Marston Sawyers, the channel has two goals. First, Heber and Marston are working on a documentary series to fill the void created by the end of CrossFit’s Fittest on Earth trilogy.
Yes. If you hadn’t heard, there will be no Fittest on Earth 2019 release. Hello? You must’ve been hibernating. CrossFit laid off their media staff last year.
Second, their vlog documents the behind-the-scenes happenings while they tour the world to create their documentary.
“While we are in production on that series, this vlog will fill in the gap and tell a behind the scenes story as it is happening through the season from our perspective. Follow the journey.”
From the description of the Bro’s first video, ACID BATH in Mat Fraser’s Garage.
“But wait,” you ask. “What do the Buttery Bros know about CrossFit documentaries?”
Well, a lot more than you do.
Heber Cannon
First of all, follow Heber on Instagram (@hebercannon) – you won’t regret it. As long as you enjoy being entertained.



This filmmaker’s first major directorial effort was on CrossFit’s 2015 Froning movie. His love for CrossFit started much earlier, in 2009. Cannon’s first CrossFit gym membership was paid for by producing monthly videos for his local affiliate. Eventually sending those videos to CrossFit, Heber transitioned to working for the company’s headquarters full time.
The success of the Froning documentary led to the creation of annual films showing the best stories of the CrossFit Games. Heber grew his directorial resume to include:
- 2018 – The Redeemed and the Dominant: Fittest on Earth
- 2017 – Fittest on Earth: A Decade of Fitness
- 2016 – Fittest on Earth
- 2015 – Froning: The Fittest Man in History
Cannon’s work extended to three years of creation on the recurring Road to the Games web series. The show followed CrossFit athletes as they prepared for the Games from 2016 to 2018.
Marston Sawyers

Rounding out this buttery twosome is director Marston Sawyers. He’s better known for his epic works as Director with Heber Cannon on the Fittest on Earth movies.
And his jokes. Dude’s got hijinks.
Sawyers’ first CrossFit movie credit was for running camera and electrical for the Froning: The Fittest Man in History documentary. He quickly followed by joining Heber with directorial credit on the Fittest on Earth trilogy:
- 2018 – The Redeemed and the Dominant: Fittest on Earth
- 2017 – Fittest on Earth: A Decade of Fitness
- 2016 – Fittest on Earth
Marston also did masterful work on the Road to the Games series with CrossFit from 2016 to 2018.
