#3 In the series of muscles and hidden connections 💪.
Did you know that your calf muscles help your heart?
We often think of circulation as a one-way story:
🫀 The heart pumps blood out.
➡️
🩸 Blood travels around the body.
➡️
🫀 Blood returns to the heart.
But there is a hidden helper in your lower leg.
Your soleus and gastrocnemius muscles form one of the body's most important peripheral muscle pumps.
When you walk, your calf muscles contract and compress the veins running through the lower leg.
The valves inside those veins help prevent the blood from flowing backwards.
So with every step your calf contracts, your veins in your lower leg are compressed, blood is pushed upwards and venous return to the heart increases.
This matters to your body because the amount of blood returning to the heart influences how much blood the heart can pump with each beat.
Your calf doesn't just help you move, it helps your cardiovascular system circulate.
Hence, why sometimes the calves are referred to as the body's "second heart".
Your cardiovascular system doesn't rely on the heart alone, it has mechanical helpers distributed throughout the body.
And the calf pump is particularly important because, when we are upright, gravity is constantly encouraging blood to pool in our lower limbs.
So calf raises (as in the video), walking, bouncing and other calf exercises are not only building muscles, burning calories, moving lymph, they are easing the burden on our heart.
And this leads me to a thought...
What if movement isnt just about muscle strength and moving our bodies, what if every single step is helping another system do its job ?
What are your thoughts? ? ?
