Your calf muscle is often called the second heartâand for good reason.
With every step you take, the calf contracts and relaxes, acting as a powerful pump that helps move blood from the lower legs back up toward the heart. This muscle-driven circulation supports venous return, reduces pooling, and helps your cardiovascular system work more efficiently.
Walking, stretching, and mindful movement keep this âsecond heartâ active. When itâs stagnant, circulation slows. When it moves, the whole body benefits.
Strong calves donât just support your anklesâthey support your circulation, your endurance, and your overall health.
