4Arm Strong has been very successful in the US, winning 6 AMA National MX/SX titles in the last two years.
As you we all know arm pump is a common issue with dirt bike riders. Lee Ramage who was a pro MX rider himself created the 4Arm Strong device to not only eliminate arm pump but to also increase grip strength by up to 30%.
Arm pump is simply muscle pump in your forearms. Too much blood in a confined area. Because very few people draw the parallel, and because it is typically associated with declining performance, for decades people have tried just about everything to find relief.
Muscle pump is the cause of the same tightness we feel after we workout in the gym. This excess blood is actually required for the muscles to perform optimally and totally necessary for power, strength and endurance. You just need to create more space in the forearms for the excess blood to be contained.
The 4Arm Strong was designed to pin the forearm muscles in their shortest position and push them in the opposite direction of the forearm stretch. The key in this aided stretch is the consistent pressure and stationary position of the part that contacts the body. Aided stretch is what expands the fascia, which is the lining of the forearm compartment, creating more space for the excess blood to be contained.
4Arm Strong is being used by all the top US MX and SX riders, even World Champion Moto GP riders are using them.
