After an intense workout, especially those where you test your physical limits, your body takes on eccentric-exercise–induced muscle damage. A symptom of this muscle damage is the soreness that you feel 24 to 72 hours after the workout, otherwise known as Delayed On-Set Muscle Soreness (DOMS).

When you use the Hydragun after your workout, any time before or during DOMS, its high-torque motor delivers a powerful, pummeling action of 3200 RPM which increases blood flow in muscles and shortens DOMS. This increase in blood flow carries more oxygen and nutrients that are essential in repairing muscle fibers, thereby relieving muscle pains and speeding up muscle recovery.
