RockCuff is an advanced blood flow restriction (BFR) training device designed to enhance muscle growth and strength gains using lighter weights. Our proprietary design achieves total venous occlusion while safely maintaining partial arterial flow, creating the optimal environment for muscle adaptation. This allows users to achieve significant results with less stress on their bodies. For more information, visit our Product Basics page.

RockCuff requires 55% less pressure than pneumatic cuffs and 85% less than elastic straps, making it more comfortable and safer. Our hand-assembled units, made in Sandy, Utah, feature medical-grade materials and precise pressure control for optimal results.

A: The RockCuff - OSx cuff requires less pressure than pneumatic cuffs or elastic straps because it applies pressure efficiently and evenly across the entire width of the cuff.

In contrast, pneumatic cuffs concentrate pressure in the center, like a bubble, engaging only 40% to 50% of the width of the cuff and requiring 35% more pressure than necessary in the center of the cuff..

Elastic straps tend to "cup" during use, limiting the area of pressure to just 15% to 20% of the width of the strap.

RockCuff's design ensures uniform pressure distribution, making blood flow restriction (BFR) training and clinical therapy safer, more comfortable, and more effective.
