4Arm Strong Sport Spray is a positively charged ionic mineral solution infused with our proprietary blend of magnesium oil, arnica, essential oils and sodium bicarbonate. This transdermal solution absorbs directly into the muscles through the skin, resulting in reduced muscle stiffness, cramping, lactic acid build-up and pain.
Proven to be an effective complement to the 4Arm Strong device, the Sport Spray also increases muscle endurance and C02, which aids in oxygenation.
The accumulation of lactic acid in the forearms causes the same symptoms of "arm pump" and since there is no way to distinguish them, this spray has been developed to alleviate the problem.
Apply the spray to your forearms before using the 4Arm Strong device to stretch your forearms.
4Arm Strong Sport Spray is a unique solution to reduce lactic acid, cramps, stiffness and pain in the forearms.
