Terms of use

Estimates, not advice

Every calculator on LiftMacro produces an estimate based on published formulas. Estimates are useful starting points, but they are not medical, nutritional, or training advice. Speak to a qualified professional before making changes to your diet or training, especially if you have a medical condition, are pregnant, or are under eighteen.

No warranty

The site is provided as-is. Reasonable care is taken to keep formulas and numbers accurate, but LiftMacro makes no warranty that results are free from error or fit for any particular purpose.

Limitation of liability

LiftMacro is not liable for any injury, loss, or damage arising from decisions made based on calculator output. You are responsible for your own training and nutrition choices.

Affiliate disclosure

Some links on the site may be affiliate links, meaning LiftMacro may earn a small commission if you make a purchase through them at no extra cost to you. Affiliate links never change the recommendation — if a product is mentioned it is because it is genuinely useful.

Changes

These terms may be updated from time to time. The date at the top of the page reflects the latest revision.
