Your Calf Muscles Are a ‘Second Heart’ and Keeping Them Active Matters

Published: 31 August 2026 · 1 min read

What Happened

Health experts say the calf muscles act like a“second heart” by helping pump blood from the legs back to the heart against gravity. Every step, heel raise or ankle movement squeezes leg veins and improves circulation, reducing the risk of blood pooling in the lower limbs.

Key Takeaways

Research suggests poor calf-pump function is linked to worse long-term health outcomes and higher mortality risk. While studies do not prove that stronger calves directly extend life, regular movement such as walking, climbing stairs and calf exercises helps support circulation, making an active lifestyle important for cardiovascular and overall health.
