#Calfmusclepump

The idea that the body houses a second heart in the legs may sound like a medical metaphor, but growing research suggests the calf muscle pump plays a real, vital role in circulatory health, especially when the heart weakens. In patients with heart failure or significant cardiac disease, the calf and ankle muscles act as a powerful auxiliary pump that helps push blood back toward the heart, offsetting some of the burden that the aging or compromised heart cannot manage alone. While the phrase “you have two hearts” captures attention, the science lies in the simple, repetitive actions of walking, standing, and gentle ankle motions that rhythmically squeeze veins, guiding blood upward through a maze of valves and toward the chest.
