Your Second Heart: How a Small Muscle Supports Whole-Body Health

What if one overlooked muscle in your legs could change the way you feel—helping you boost circulation, protect your heart, balance blood sugar, and support long-term health?

In Your Second Heart, Marvin McKenzie shares his personal journey of exploring the soleus muscle, often called the “second heart” for its vital role in returning blood from the lower body to the heart. After years of navigating insulin resistance, fibromyalgia symptoms, and caregiving for his wife through cancer and osteoporosis, Marvin set out to better understand how small, consistent movements could make a big difference for his own health.

This book isn’t a medical manual. It’s a thoughtful reflection on one man’s study of self-care, simple routines, and the science behind how movement supports whole-body vitality.

✅ How small, daily habits can help reduce leg swelling, fatigue, and blood sugar spikes.
