About Lyf.Fit

Lyf.Fit is an independent fitness and longevity publication. We publish evidence-based articles on training, nutrition, recovery, and supplements, and we build free interactive training tools — 18 of them and counting — including calculators, trackers, timers, and reference databases that work right in your browser, no account required.

Who runs this site

Lyf.Fit is built and run by a software developer and lifelong fitness enthusiast who writes and edits here as Jordan Hale. Jordan builds the site, its tools, and its publishing pipeline, and acts as the editor who reviews every article before it goes live.

To be clear about what we are and are not: Jordan is an engineer and practitioner who curates published research and builds training tools — not a physician, registered dietitian, or licensed healthcare provider. Nothing on this site is medical advice. For anything touching a medical condition, medication, or diagnosis, talk to a qualified professional. Our full medical disclaimer explains this in detail.

What we publish

Articles are organized into six categories — from performance and strength to metabolic health, supplements, and longevity — and are written to answer real questions with mechanisms and numbers rather than hype. Alongside the articles, our interactive tools let you put the concepts to work: log workouts, track macros and hydration, estimate one-rep maxes, run interval timers, and more. The tools are free, work offline, and keep your data on your device unless you choose to create a sync account.

How our content is made

We are transparent about our process: articles are drafted with AI assistance against a strict editorial specification, grounded in published research, machine-validated, and human-reviewed before anything is published. The full process — including our sourcing standards, AI disclosure, and corrections policy — is documented in our editorial policy.

How the site makes money

Lyf.Fit is supported by affiliate commissions: if you buy a product through one of our links (for example, on Amazon), we may earn a small commission at no extra cost to you. Affiliate relationships never change an article's conclusions, and we never quote or guarantee prices. The disclosure appears on every page of the site and on every article that contains affiliate links.
