Leonardo Schulz Cardoso, known to millions as Leo Stronda, is one of Brazil’s most recognisable fitness faces
He first found fame as a rapper, then rebuilt himself as a bodybuilding YouTuber and that second act made him even bigger.
Born in Rio de Janeiro, Leo turned a teenage love of lifting into a career that now spans music, fashion, YouTube and his own gym.

Early Life in Rio
Leonardo grew up in Rio de Janeiro, where he became childhood friends with Diego Villanueva, the friendship that would shape his whole career.
He got interested in bodybuilding at 16, training while still at school and dreaming of a physique to match his music ambitions.
In 2006, still teenagers, Leonardo and Diego formed the hip-hop group Bonde da Stronda, recording at home and putting their songs on the internet.

Music Career: Bonde da Stronda
Bonde da Stronda started as a four-piece, but soon settled into a duo: Diego, known as Mr. Thug, and Leo himself.
Their debut album, Nova Era da Stronda, arrived in 2009, followed by A Profecia in 2011 and the Corporacao mixtape in 2012.
Leo’s two worlds collided in the single “Bonde da Maromba,” a celebration of gym culture whose music video was released on December 17, 2012.
Music profiles list his active years in music as 2006-2023, and today he is best described as a former rapper turned full-time fitness creator.
Fabrica de Monstros and YouTube Fame
Leo’s biggest platform was Fabrica de Monstros (Monster Factory), the Brazilian bodybuilding channel he fronted.
The channel passed 2.5 million subscribers, then Leo lost it in a contract dispute, a setback he has spoken about openly since.
He started again from scratch with a channel simply called “Leo Stronda,” which now sits at around 3 million subscribers.
Alongside YouTube, he built his own clothing line, XXT Corporation, turning the “monster” brand into a business.
Leo Stronda in 2026
Leo has not faded away, he has moved into the presenter and gym-owner side of Brazilian bodybuilding.
He now runs a new Monster Factory gym, which he showed off in his own videos as the home base for his training content.
In 2026 he has been appearing on Integral TV, training and talking physique with Brazil’s new generation of pros, including Leandro Peres and Lucas Tarzan.
That role suits him: less a man chasing a stage placing, more a host and mentor for athletes who are.
Contest Record: The Honest Picture
Some older profiles call Leo a bodybuilder who “participated in several competitions,” but none of them names a contest, a division, or a placing.
We checked the places a pro record would show up, and found nothing. So this refresh does not credit him with wins he cannot be shown to have.
| Competition | Record |
| IFBB Pro League pro wins | None verified – 0 |
| Mr. Olympia appearances | None as a competitor – 0 |
| Arnold Classic Ohio | No appearance found – 0 |
| Arnold Classic UK | No appearance found – 0 |
| Best verified result | No verified pro contest placing |
That contrast is worth stating plainly: fellow Brazilian Men’s Physique pro Diogo Montenegro has stood on the Olympia stage, while Leo’s stage has always been YouTube and the gym.
Likewise, Vitor Chaves built his name with pro wins and an Arnold Classic UK title, a contest career Leo simply does not have on record.
Leo’s achievement is different, and real in its own way: he made bodybuilding mainstream entertainment in Brazil before most pros had a channel.
Diet Plan
Leo’s long-stated approach is simple: whole foods first, with lean protein at the centre of every meal.
He talks about chicken, fish and other lean proteins for muscle repair, plus complex carbs like sweet potatoes for training energy.
Healthy fats from nuts, avocado and olive oil round out the plan, and supplements only fill gaps, on the road, for example.
No verified day-by-day meal plan of his is published, so treat the above as his stated principles, not a prescription to copy.

Workout Routine
For muscle growth, Leo has long favoured heavy lifting in the 8-12 rep range, the classic hypertrophy zone.
He adds drop sets, extra sets with lighter weight and no rest, to push muscles past failure on key exercises.
Compound lifts like squats, bench presses, deadlifts and rows do the heavy work, with isolation moves added to shape individual muscles.
When he wants to lean out, he flips the formula: lighter weights, higher reps, chasing the burn rather than the load.
Rest days are part of the plan too, muscles grow when they recover, not just when they are trained.

Life Beyond the Gym
Like Paulo Muzy, another Brazilian fitness figure with a huge online following, Leo’s influence now comes from content, coaching-style videos and gym culture, not competition.
His content mixes training, nutrition talk, guest workouts and honest conversation about injuries, recovery and staying consistent.
At 34, Leo Stronda’s story is a reminder that a fitness career does not have to end on a contest stage to matter.
He went from teenage rapper to the face of Brazilian gym YouTube, and in 2026, he is still building monsters.
