About FitDeck

FitDeck is a collection of free fitness and workout calculators. We built it because most calculator sites are slow, cluttered with popups, or request sign-ups. FitDeck is the opposite: fast pages, clean interface, instant results — built for lifters, runners and everyone in between.

Every calculation happens locally in your browser — your numbers never leave your device. We don't require accounts, we don't store inputs, and the site is supported by unobtrusive ads.

Part of the Deck family: FreeDeck (free games) and PromoDeck (coupon codes).
