What Exactly Is It?

Typically refers to a massaging device designed in a "U" shape, often used to provide targeted relief and relaxation to specific parts of the body, like the neck, shoulders, back, or even the legs and feet. 

Kneading And Vibration

The massage movements, such as kneading or vibration, stimulate the muscles and soft tissues, which in turn encourages better blood flow. This can help loosen up tight areas, making it easier for blood to flow through restricted muscles and tissues.

Reducing Muscle Stiffness

When muscles are stiff and tight, blood circulation can be restricted. By massaging these areas, the muscle fibers loosen, helping to improve overall blood flow. 

Promoting Lymphatic Drainage

In addition to improving blood circulation, massage can also promote lymphatic drainage, which is the body's way of removing waste products and toxins.

Improved Oxygen And Nutrient Delivery

With enhanced circulation, oxygen and nutrients are delivered more efficiently to muscles and tissues, helping to accelerate recovery after exercise and reduce feelings of fatigue or soreness.
