DYNAMIC SHOULDER + ELBOW STABILIZATION

The Kinetic Arm is the world's first dynamic dual-joint arm stabilizer—delivering medical-grade orthopedic support to both the shoulder and elbow simultaneously during high-stress arm movements like throwing, swinging, serving, and rotational motions.

Powered by multi-patented MuscleWeb® technology, it delivers motion-responsive stabilization that activates during vulnerable phases of movement—scientifically proven to significantly reduce dynamic arm stress and mechanical load that can lead to fatigue, discomfort, and overuse strain.

Doctor-recommended for sports, activities, and occupations that demand high arm activity and repetitive use, Kinetic Arm helps support the arm, reduce strain, and maintain consistent mechanics—so you can stay strong and keep doing what you love.

Redefining arm support

Beyond Compression. Beyond Bracing. Medical-Grade Engineering.

Traditional arm sleeves compress uniformly. Rigid braces limit mobility. Neither offers dynamic, dual-joint stabilization that actively supports your arm during motion.

Kinetic Arm is engineered differently. This dynamic arm stabilizer provides adaptive, multi-directional support to both the shoulder and elbow—engaging during the most vulnerable phases of movement to reinforce the arm exactly when and where it's needed most, without limiting velocity, power, or range of motion.

Used in-game, during training, and throughout active recovery, Kinetic Arm helps athletes and active individuals move with confidence, reduce strain from repetitive motion, and support healthier movement patterns over time.

IMPRESSIVE TECHNOLOGY

MuscleWeb® DESIGN

Our MuscleWeb® technology features an intelligent design with a bio-knit weave and HD-bonded flexible polymers strategically placed to reinforce the shoulder and elbow. This precision-engineered web network delivers medical-grade support that activates dynamically during high-stress movements—stabilizing both joints without restriction to help reduce distraction forces and support more efficient arm mechanics.

" I have now used it with a variety of my athletes in physical therapy and have seen it reduce pain with throwing from a 7/10 to a 0/10 by just simply putting it on. The Kinetic Arm’s ability to offload stress while allowing proper mechanics and full ROM, the process can be streamlined with better outcomes. Highly recommend 10/10!"
