Abhishek Kumar
Founder and developer, TrainingCalcs
Abhishek Kumar builds and maintains TrainingCalcs. He is a software engineer and the developer behind ToolzPoint, and he writes every calculator, guide and FAQ on this site.
His work here is implementation and verification rather than original research: he reads the published paper or governing-body document behind a formula, writes it as a plain function, and covers it with automated tests that reproduce the worked examples from the source. The DOTS implementation, for example, is checked against real competition results from the OpenPowerlifting database, and the Wilks implementation against Robert Wilks' own coefficient tables.
Every formula on the site is traceable to a named source listed on the page that uses it. Where the research is uncertain or the numbers are only estimates — body-fat-dependent indexes, calorie burn, fasting outcomes — the page says so instead of presenting a single confident number.
The limits of this expertise
Abhishek is not a doctor, dietitian, physiotherapist or certified strength coach, and nothing on this site is a substitute for one. The calculators report what published formulas produce for the numbers you enter; decisions about your diet, supplements, medication or training belong with a qualified professional who knows your history.

How this site is built and checked
Every formula, source and review date on TrainingCalcs follows the same rules, written down in our editorial policy. The limits of what the calculators can tell you are set out in the medical disclaimer.
