Glute training with Renatinha Costa

OPERATION BRAZILIAN BOOTY.

Before she became the go-to name for glutes, Renatinha spent years hearing a nickname that stung: “Renata Fonseca da Bunda Seca” (roughly, “Flat-Butt Renata”). The method that erased that nickname now has a name — and a spot with your name on it.

The Story

YOU’VE ONLY SEEN THE RESULTS.

Everyone knows today’s Renatinha: the glutes, the definition, the titles, 20+ years of lifting. Almost no one knows the girl who was mortified by her own body.

“You look at me and see results. I see thousands of workouts that got me nowhere. Mistakes. Frustration. And a nickname that hurt.”

— Renatinha Costa
RENATA FONSECADA BUNDA SECA

She trained. But she trained wrong. She thought it was genetics — that her body would never change. She could have just accepted that’s how it was. That’s when everything turned around.

The Turning Point

THE PROBLEM WAS NEVER A LACK OF WILLPOWER. IT WAS A LACK OF STRATEGY.

Renatinha could have accepted it was “just genetics.” Instead, she chose to study: strength training, biomechanics and training methodology. She learned how muscle really grows — and completely transformed her own body.

Today she could simply post her own workouts. Instead, she’d rather show you the way — because no one should lose years training without a strategy the way she did.

“I COULD HAVE ACCEPTED IT. BUT I CHOSE TO STUDY.”

Strength training. Biomechanics. Strategy. That’s what changed everything.

From nickname to method

THE NICKNAME BECAME A METHOD. THE METHOD BECAME A MISSION.

That’s how the RC Training platform was born: everything Renatinha wishes she’d learned back at the start, all in one place. Inspired by her journey, Operation Brazilian Booty was created for women who dream of building their glutes the smart way, with a 100% personalized training plan.

Is this for you?

IT DOESN’T MATTER IF YOU’RE JUST STARTING — OR YOU’VE TRAINED FOR YEARS WITHOUT RESULTS.

“I’VE NEVER WORKED OUT”

Your plan starts from your fitness assessment: it respects your level and your routine, and teaches you every movement with a detailed video.

“I TRAIN AND NOTHING CHANGES”

The same problem Renatinha lived with for years. It’s not a lack of willpower — it’s a lack of strategy. Here, the strategy comes ready-made for you.

“I THINK IT’S MY GENETICS”

She thought so too. The right strategy, consistency and guidance proved otherwise. Your body responds when your training is smart.
