The Second Difference Between Katsu and Standard BFR

The difference between BFR and katsu is actually the shape of the air bladder inside the band. With katsu, there is a narrow air bladder and when it inflates, it inflates in an oval shape. That oval shape means that the pressure on the arterial flow is minimal. But the pressure on venous flow, so from your lens back to your torso, is much more. And that is the secret that Dr. Satra found. He wanted to engorge the vascular tissue of your limbs and blood. It was the catalyst for all of these biochemical changes that you and I know of so well.
