Brazilian Jiu Jitsu
Two years ago, I started my fitness journey weighing nearly 100 kilograms. Through consistent training, discipline, and dedication to Brazilian Jiu-Jitsu, I have successfully transformed my body and mindset, currently weighing 77 kilograms. I actively participate in competitions and, thanks to the guidance of my skilled coaches, I have achieved multiple first-place finishes in my category. This journey has not only improved my physical health but also strengthened my perseverance, strategic thinking, and mental toughness—qualities I bring into all areas of my life.
