4Arm Strong Sport Spray

4Arm Strong Sport Spray is a positively charged ionic mineral solution infused with 4Arm Strong's 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 CO2, which aids in oxygenation.
• Sold in 2 and 8-ounce spray bottles.
