Welcome to AthFist! We’re more than just a website; we’re a dedicated team of fitness enthusiasts, data nerds, and wellness advocates on a mission to simplify your health and fitness journey.
We know how overwhelming it can be. Between counting calories, figuring out your ideal heart rate, planning macros, or tracking your strength progress, the numbers can feel like a second job. That’s where we come in.
Our Story: From Frustration to Solution
AthFist was born out of a simple, personal frustration. Our founder, while training for a marathon and managing weight, spent more time switching between confusing spreadsheets, outdated online charts, and generic fitness apps than actually working out. He thought, “There has to be a simpler, more accurate way.”
He was right. So, we built one. We started with a few core, meticulously researched calculators and have been growing our toolkit ever since, based on real user feedback and the latest exercise science.
Our Tools: Your Fitness Toolkit
Whether you’re a beginner taking your first steps or an elite athlete fine-tuning performance, AthFist offers a curated collection of reliable calculators:
Body Composition: BMI, BMR, Body Fat %, Ideal Weight.· Training & Performance: One-Rep Max (1RM), Target Heart Rate, Calorie Burn.· Nutrition & Goals: Macro Calculator, Calorie Deficit/Surplus, Protein Needs.· And many more, with new tools added regularly based on your needs.
