[About BFR Training](https://support.saga.fitness/about-bfr-training?hsLang=en) # How your cuffs measure pressure (LOP) LOP (limb occlusion pressure), also sometimes known as AOP (arterial occlusion pressure), refers to the amount of pressure required to fully restrict arterial blood flow to a limb. This measurement is used to personalize BFR training with the cuffs inflating to a set percentage of your LOP (e.g. 50%). For example: - LOP = 200 mmHg - 50% occlusion = 100 mmHg LOP is measured automatically by the cuffs using a built-in pressure sensor, similar to a blood pressure cuff. The sensor detects changes in blood flow and uses this data to determine your individual occlusion pressure. - [Getting Started](https://support.saga.fitness/getting-started?hsLang=en) - [Using BFR Cuffs](https://support.saga.fitness/using-bfr-cuffs?hsLang=en) - [Orders & Shipping](https://support.saga.fitness/orders-shipping?hsLang=en) - [About BFR Training](https://support.saga.fitness/about-bfr-training?hsLang=en) - [Troubleshooting](https://support.saga.fitness/troubleshooting?hsLang=en) - [Partner with SAGA](https://support.saga.fitness/partner-with-saga?hsLang=en) [![SAGA Logo Black Small](https://app-na2.hubspot.com/api/filemanager/api/v2/files/371516251834/signed-url-redirect?portalId=242388504 "SAGA Logo Black Small")](https://saga.fitness/) [CONTACT US](https://40b860.share-na2.hsforms.com/2FCbboByNQkirYweuf1hibg) © SAGA Fitness [Privacy Policy](https://saga.fitness/policies/privacy-policy)
