The Calf: Your Body’s Second Heart

When you think of a body part being efficient at pumping blood, the heart comes to mind right away. I never thought too much about what the calf muscle was responsible for, other than functional movements and exercising. But then I saw a headline about how the calf recirculates venous blood back to the heart and throughout the body.

The calf is made up of two muscles. The soleus and gastrocnemius come together to form the Achilles. Overall fitness is important and focusing on particular muscles can take your body composition to the next level. We all have our favorite exercises and activities, but it’s crucial to make sure we’re hitting all the muscle groups. Weak calves can bring on an array of issues that could make it more difficult to perform everyday functions. Some of these challenges are listed here:

Poor walking mechanics

Achilles strains

Overpronation of the foot (inward rolling)

Calf cramps

Decreased shock absorption

Pain – hip, knee, shin, hamstring, back

Heel pain – plantar fasciitis

Stress fractures

Blood clots

Varicose veins

Strength of the calf muscles is a major determinant of health. Walking speed is now considered to be the 6th vital sign, since it is a reflection of a person’s overall health and well-being. If a person walks very slowly then they are more likely to have health challenges such as poor balance, cognitive decline, falls, or some form of serious illness. We see slow walkers every day at the grocery store, airport, or sporting events. It’s surprising how many people need walkers or wheelchairs at the airport. I wrote an article about how walking is the most underrated exercise and I’m a firm believer that it’s one of the easiest and most efficient ways to stay active and mobile.

As mentioned above, weak calves may hinder independence and can keep individuals from enjoying life. Once you start incorporating a strength training routine, you will more than likely notice a difference in daily chores. You should have better stamina and more enjoyment while running errands. Below is a list of benefits that occur with consistent calf training explained by the American Sports & Fitness Association:

Ankle, knee stability

Flexibility/mobility

Improved circulation

Reduction in swelling

Improved posture

Enhanced athletic performance

Lower risk of injury

As I thought about my current workout, I realized that I needed to be more consistent with targeting my calves. I started looking for ways to improve calf strength and function and came up with a list of exercises and activities that are easily accessible.  I already include several of these in my workout:

Standing calf raises (add dumbbells)

Seated calf raises (add weight)

Jump rope

Plyometrics

Rebounding (mini trampoline)

Walking on an incline, on uneven terrain, or with a weighted vest

Jump squat

Running up a set of stairs or bleachers

Riding a bike

Tip toe farmer’s walk

Walk backwards (retro)

High knees

Butt kicks

Sprints

Downward dog

Leg strength has a direct relationship to brain health and calf muscle strength can be an indicator for dementia. A strong calf muscle helps circulate blood flow throughout the body improving cognitive brain function. Calf circumference is also a mortality predictor (Science Direct.) Research shows that improving leg strength adds years to your life because stronger legs equal lower mortality (Harvard Health.) This is a critical marker of healthy aging.

Strengthening your calf muscles goes far beyond improving appearance. It’s a key investment in your overall health. Strong calves support balance, stability, and mobility, reducing the risk of injury and enhancing performance in everyday activities. By incorporating simple calf exercises into your routine, you’re not just building muscle, you’re reinforcing the foundation that keeps your entire body moving with strength and confidence.
