“Never meet your heroes” is an expression that hits home for Kai Greene when recounting his first time meeting pro bodybuilder Chris Cormier
Bodybuilding legend Kai Greene continues to spark conversation in the sport with his podcast, The Kai Greene Effect. In a recent episode, Greene tackled some of the biggest questions shaping bodybuilding today — from why Classic Physique and Men’s 212 athletes are successfully moving into Men’s Open, to how iconic champions like Dorian Yates and Ronnie Coleman shaped the sport’s evolution, to debates over science-based lifting, diuretics, and even diet choices at restaurants.
Here’s a brief breakdown of the topics discussed this week:
- Kai Greene explains why more Classic Physique and Men’s 212 athletes (like Keone Pearson) are jumping into Men’s Open — and winning big.
- Kai Answers: Do Dorian Yates, Ronnie Coleman, or the judges deserve credit (or blame) for bodybuilding’s mass monster era.
- Kai’s take on the “science-based lifting” debate and why following it like a religion can hold athletes back.
- Fun lightning round answers, from Kai’s awkward encounter with Chris Cormier to the supplement he avoids and his go-to chain restaurant.

Classic Physique and Men’s 212 Athletes Crossing Into Men’s Open
One of the main topics was the trend of Classic Physique and Men’s 212 competitors stepping onto the Men’s Open stage — and winning. Most recently, Keone Pearson made headlines by leaving the 212 division to compete in Open, showing that the transition is not only possible but often highly successful.
Kai Greene sees this as a positive development. He explained that divisions like Classic Physique and 212 allow athletes to “find themselves” first. By competing in those categories, bodybuilders can figure out their strengths, refine their physiques, and develop their confidence. Later, if they’re suited for the sheer size demands of Men’s Open, they can move up without being thrown straight into the deep end.
This flexibility has reshaped the sport, creating a clearer pathway to the biggest stage in bodybuilding.
How Classic Physique Changed Men’s Open
Kai Greene reflected on the 2010s when the Men’s Open division was dominated by the so-called “mass monster effect.” Size was everything, often at the expense of aesthetics. Competitors were getting blockier, with bloated midsections and GH guts. Many fans felt the look was drifting too far from bodybuilding’s original ideals.
The introduction of the Classic Physique division was meant to course-correct. Designed to emphasize symmetry, proportion, and aesthetics reminiscent of bodybuilding’s golden era, Classic Physique quickly gained popularity.
And according to Greene, it didn’t just succeed as a division — it influenced Men’s Open as well. The rise of Classic Physique athletes, especially those crossing over and winning in Open, forced judges and competitors to prioritize balance and aesthetics alongside mass. Today’s Open competitors still bring incredible size, but the look is more refined and polished than the blocky physiques of a decade ago.
Do Iconic Physiques Shape the Sport’s Future?
Another thought-provoking discussion on the podcast centered around how much influence individual legendary physiques have on bodybuilding’s direction.
Kai Greene pushed back against the idea that one person alone changes the sport. Yes, Dorian Yates in the 1990s and Ronnie Coleman in the 2000s embodied the mass monster era, but they weren’t the only ones chasing that look. Judges rewarded their physiques, and other bodybuilders pursued the same path.
“It would be unfair to blame Dorian alone,” Greene noted. “The judges had a role, and other athletes were pushing the same thing. Dorian just did it best.”
Greene explained that if the judges had favored a more aesthetic physique like Flex Wheeler’s over Ronnie Coleman in 1998, bodybuilding history might look different. Athletes often chase what wins, and if judges sent another message, competitors would have adjusted their goals.
He also reminded listeners that size-chasing didn’t start with Ronnie. Even Lee Haney, despite stopping short of extreme mass, was part of the evolution toward bigger physiques.
Science-Based Training: Helpful or “Snake Oil”?
The episode also explored Sam Sulek’s controversial take that “science-based lifting” is a snake oil idea. Kai Greene didn’t dismiss science outright — far from it. He acknowledged the value of science in understanding what works, but he also highlighted its limits.
Science evolves. What experts preached 30 years ago isn’t always what’s recommended today. And in the modern fitness industry, many coaches and influencers use the label “science-based” to sell programs as the one “right” method, which Greene sees as misleading.
Instead, Greene emphasized blending science with self-awareness:
- Science offers guidance, but no method works for everyone.
- Bodybuilders often push boundaries that science only catches up to later.
- Rigidly following “science-based” methods can backfire if you ignore your own body.
Kai Greene pointed to the contrast between Branch Warren, who relied on instinct and grit, and Ben Pakulski, who leaned heavily on science. Both approaches worked — because bodybuilding success depends on individuality.
Lightning Round: Personal Insights from Kai Greene
The episode wrapped up with a fun but revealing lightning round of questions.
- On meeting heroes: Kai Greene recalled how Chris Cormier, one of his idols, unintentionally left him feeling slighted when he flirted with Greene’s girlfriend at a show. Although the experience stung at the time, Greene now sees it as a lesson in maturity and holds no grudges.
- On supplements to avoid: Greene mentioned niacin (a B-vitamin) as one that he personally avoids.
- On dining out: Greene admitted he occasionally eats at fast-food chains when traveling, but prefers places like Outback Steakhouse. At sit-down restaurants, he customizes meals by asking for no butter or certain oils, but doesn’t go overboard with requests.
Wrap Up
The Kai Greene Effect once again lived up to its name, offering not just opinions but perspective from one of bodybuilding’s most thoughtful champions.
From the rise of Classic Physique to the ongoing influence of judging, Greene stressed that bodybuilding is a constantly evolving dialogue between athletes, judges, and fans. Science, tradition, risk, and individuality all play a role in shaping the sport’s future.
At the heart of it all, Greene’s message is clear: bodybuilding is not about one path or one physique. It’s about finding what works, respecting the process, and constantly adapting as the sport — and the science — continues to evolve.
