About TrainingHardcore

What This Site Is

TrainingHardcore is a small, independent site built around a set of fitness calculators and a Muscles & Movement museum. There is no company behind it beyond the person who built and maintains it, and no claim to be a gym, a certification body, or a substitute for a coach. It runs on display advertising, the same as most free tool sites — that’s what covers hosting and keeps every calculator free to use, with no account and no paywall.

What This Site Is Not

It is not a source of medical, nutritional, or professional training advice. Every number a tool gives you — a one-rep max, a body-fat percentage, a macro target, a recovery window — is a general estimate produced from a formula or a published convention, applied to the numbers you type in. It is not a diagnosis, a prescription, or a guarantee of how your own body will respond. If you have a health condition, are new to training, or are recovering from an injury, talk to a physician or a qualified trainer before you act on anything you read here. TrainingHardcore is not affiliated with, endorsed by, or certified by any gym chain, federation, or exercise-science organization it references.

The Tools

The core of the site is the tools page, twelve calculators covering the questions that come up constantly in training: the One-Rep Max Calculator (Epley and Brzycki formulas plus a training-percentage table), the BMI & Body Composition Analyzer, the Body Fat Calculator (U.S. Navy tape method), the Macronutrient Calculator, the Calorie Burn Calculator (MET values), the Heart Rate Zone Calculator, the Workout Volume Calculator, the Body Measurement Tracker, the Recovery Time Calculator, the Strength Standards Checker, the Training Split Generator, and the Flexibility Assessment Tool. Each one runs a plain, disclosed calculation — no hidden weighting, no upsell.

The Museum, Blog, and Guides

Past the tools, the Muscles & Movement Museumis a set of galleries on the major muscles you train, the lifts and equipment that build them, and the physiology behind getting stronger — every entry, image, and fact drawn from Wikipedia and Wikimedia Commons, kept as a reference rather than a claim of original research. The blog and learn sections carry longer articles on programming, conditioning, and nutrition for readers who want more than a single number back.

The Honest Version

This is one person’s tool site, not an institution. There’s no founding story to tell and no team bios to list — just a working set of calculators, maintained and occasionally expanded when a gap becomes obvious. The calculators are built to be correct and clearly explained, the formulas and standards behind them are named rather than hidden, and nothing on the site is presented as more authoritative than it is. If a number looks wrong, say so; formulas get rechecked and fixed when they are.
