Our calf muscle

Your calf muscles are a “second heart” — you need to move them to safeguard your heart health.  Calf muscles play a crucial but often overlooked role in heart health by acting as the body’s “second heart.” Every time they contract—while walking, standing on your toes, or flexing your ankles—they compress deep veins in the lower legs and help push blood back toward the heart against gravity. This calf “muscle pump” improves circulation, reduces blood pooling, and lessens the workload on the heart. Research cited in the article notes that efficient calf function supports healthy venous return, lowers the risk of swelling, fatigue, and varicose veins, and is associated with better overall cardiovascular performance. Conversely, prolonged sitting or standing, sedentary habits, dehydration, and poor posture can weaken these muscles and impair circulation, contributing to leg discomfort, vein problems, and added strain on the cardiovascular system. Strengthening the calves is presented as a simple, accessible way to support heart health from the ground up. The article recommends integrating small, frequent movements into daily life: calf raises at the counter, walking breaks every hour, toe lifts and ankle circles at a desk, and seated heel raises for those with limited mobility. While compression socks may help, regular movement is emphasized as the most effective “medicine” for circulation. The article also advises seeking medical evaluation for persistent leg swelling or heaviness, calf pain with walking, varicose veins, skin changes, tingling, numbness, or cold feet, as these may signal underlying circulation or vascular issues.
