About the Author

I’m Johan Latsky, the creator of CoreSifu. I hold a Bachelor of Science in Agriculture (BScAgric) and focus on studying and writing about exercise physiology, human performance, and nutrition.

Through CoreSifu, I translate scientific research into practical, easy-to-understand explanations that help readers better understand their bodies.

I use a combination of scientific literature, textbooks, and AI-assisted research tools to help organise and clarify complex topics. All content is reviewed and shaped through my own understanding and interpretation before publishing.
