KetBiaThe person behind KetBia
Personal trainer, fitness coach, martial-arts enthusiast and bilingual UGC content creator — also known online as Ketlin, Ketlin Bianca, Ketlin Bianca Llantoy, Ketlin Llantoy or Ketlin Reis.
Photos only tell half the story — this is what a real KetBia session looks like. Energy, focus and intensity, the same mindset I bring into every plan I build for my clients.

Fitness changed my life long before it became my career. What started as a personal search for discipline and confidence turned into a passion for helping others find the same thing in themselves. Today, through KetBia, I guide people with personalized training routines, nutrition guidance and honest, no-excuses coaching — because I believe real change comes from consistency, not motivation.

Beyond the gym floor, I train and study martial arts — Brazilian Jiu-Jitsu and MMA-style conditioning shape the way I coach. Real movement, real intensity, real results. That same mentality is what I bring into every personalized routine I build for my clients: train with purpose, not just for the sake of training.

Outside of one-on-one coaching, I also create bilingual UGC (user-generated content) — fitness, lifestyle and beauty videos that connect brands with real audiences. Brazilian by birth and Peruvian by life, I create content in Spanish, Portuguese and English, and my work has reached millions of people across TikTok and Instagram.
Behind every video, every plan and every WhatsApp reply, there's a team of two. Barclay Leach is a systems engineer with his own passion for the gym and MMA — and my partner, in life and in KetBia. He built and runs this website, manages our social presence and handles all the technical pieces so I can focus on training, coaching and creating. KetBia exists because of the two of us — this brand, this page, this whole journey, we built it together.
