Embed the calculators

Put any of the eight calculators on your gym, club or coaching site. Copy the code under the one you want and paste it into your page.

Free, with no account and no sign-up. There is no key to request and nothing to install.

Nothing tracked on your site. The embedded calculator carries no ads and no analytics, and it sets no cookies. It loads only its own stylesheet, font and script from liftandpace.com. Anything a visitor types stays in their browser.

Always current. The code points at the live calculator, so fixes and updates reach your page without you changing anything.

Each embed shows the inputs and the main result, with a link to the full breakdown on this site. The code, a copy button and a live preview sit below for each one. The height is set so the calculator's tallest state fits at a phone's width without scrolling inside the frame. On a wider column you can lower it a little.
