FAQ's

How do B3 Bands work?

B3 Bands are equipped with a patented, multi-chambered design that safely and effectively reduces blood flow to the working muscles during exercise — a method known as Blood Flow Restriction (BFR) training.

Unlike devices that require a pressure sensor to determine limb occlusion pressure (LOP), B3 Bands are designed to apply light, consistent pressure that’s safe for all users without needing to calculate or set exact mmHg levels. The bands use a hand pump to inflate, and their design ensures uniform pressure distribution around the limb without completely restricting blood flow.

Here’s how they work:

The bands are gently inflated to a personalized level that allows arterial inflow (blood going into the limb) while restricting venous return (blood leaving the limb).
This causes a natural and rapid accumulation of metabolites like lactate, which triggers a hormonal response including a surge in Human Growth Hormone (HGH).
The result: muscle growth, fat burning, and enhanced recovery — all with light weights or low-impact movements.

B3 Bands are backed by research, trusted by doctors and athletes, and safe for all ages and fitness levels.
