About TrainingCalcs
17 free calculators for lifters and endurance athletes, each built from a published formula and signed with the date it was last checked.
TrainingCalcs is a small, independent site run by one person. Each tool does one job well: fast, mobile-friendly, no sign-up, and no numbers of yours sent anywhere.
Who runs it
TrainingCalcs is built and maintained by Abhishek Kumar, founder and developer, operating as ToolzPoint (Abhishek Kumar), India. He writes every calculator, guide and FAQ here, and every page carries his name and a review date.
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 we build the calculators
- Published sources. Every formula comes from a peer-reviewed paper or a governing body's own document, listed with a link in the Sources section of the page that uses it.
- Tested maths. Formulas are plain functions covered by automated tests that reproduce the worked examples from their sources — and, for powerlifting scores, real competition results from the OpenPowerlifting database.
- Dated reviews. Each page shows when its formula and copy were last checked against those sources.
- Honest ranges. Where the research gives a range or a wide error, the page says so instead of inventing one precise answer.
- Your numbers stay yours. Calculations run in your browser; we never receive the values you type.
The rules behind all of that — sourcing, review schedule, corrections, funding and how AI tools are used — are written down in our editorial policy.
What this site is not
It is not a medical service and nobody here is your clinician. The calculators give general fitness information; the medical disclaimer sets out the limits, and pages about supplements, fasting and calorie targets carry a warning next to the result.
What's here
17 calculators and 15 in-depth guides, covering strength scores, body composition, nutrition and endurance. Browse all calculators or read the guides.
