4ARM STRONG

4Arm Strong is a cutting-edge tool for more than one reason. Reducing arm pump speaks for itself, increasing grip strength without resistance training is monumental! 4Arm Strong is also essential for people that have had wrist injuries that resulted in limited range of motion. 4Arm Strong will help people with this condition regain their grip strength. 4Arm Strong is the first thing my riders use before they throw their leg over their bike. 4Arm Strong is the world’s only self therapy device that can reduce arm pump, increase grip strength and grip strength endurance, relieve tennis and golfer’s elbow pain, reduce the risk of elbow and forearm overuse injuries and relieve and prevent Carpal Tunnel symptoms. 4Arm Strong is constructed out of durable Clear Polycarbonate, 4-40 stainless steel and ultra strong, lightweight 6061 aluminum used in the medical industry. Because 4Arm Strong comes in two sizes, when ordering please provide your forearm measurement. Measure the circumference of the largest part of your forearm. 4Arm Strong is a self-therapy device that creates traction on the forearm muscles toward the elbow while stretching in the opposite direction. This type of assisted stretch can expand the fascia and lengthen the forearm flexor muscles in the anterior and posterior compartments of the forearm, as well as create a stretch in front of the elbow that otherwise couldn’t be achieved. Anterior describes the inside or bottom of the forearm and posterior describes the top of the forearm. Expanding the fascia and stretching the forearm flexor and extensor group muscles can create more space in the forearm compartment, which allows blood to flow into the muscles with less constriction. Less constriction translates into less arm pump. It also results in a freer, less restrictive movement which almost always results in greater grip strength and freedom of movement in the hands and wrists.
