About Fitness Basics

About the Author

I'm David, a software engineer who got into fitness five years ago and made every beginner mistake in the book. I followed bad advice, bought unnecessary supplements, and wasted months on ineffective programs.

This blog exists so you don't have to make the same mistakes. Everything I write is backed by research — I link to actual studies, not Instagram influencers. No supplements to sell, no training programs to upsell. Just honest, evidence-based fitness advice for people who are just getting started.
