BFR cuffs positioning and fit

Arms: Place the BFR cuff at the highest point on the arm, just under the deltoid as pictured below.

Legs: Place the BFR cuff at the highest point on the leg, just under the glute as pictured below.

You can assess the fit of your cuffs when they are not inflated. You should be able to fit two fingers between your limb and the strap for an ideal fit.

If only one finger fits, this indicates that the cuff is too tight. If three or more fingers fit, the cuff is too loose. 

Adjust the fit of your cuffs only using the Velcro strap when deflated, and use the app to control inflation level.
