BFR cable rope hammer curl Instructions

The blood flow restriction (BFR) cable rope hammer curl is an arm movement that builds biceps size and strength using a cable stack, rope grip, and blood flow restriction bands. It is popular in high-rep "pump"-style arm workouts. The bands should be placed as high as possible on your arms, at a tightness of no greater than 8 on a scale of 10. Most BFR workouts recommend using a far lighter weight than usual, perhaps as low as 25-50 percent of a normal working weight.
