How Our Muscles Evolved from Walking: The Foundation of Human Movement (Part 2)

Walking is more than just a daily activity; it’s a fundamental movement that shaped the evolution of our muscles and overall physiology. Our ability to walk upright on two legs, known as bipedalism, is one of the defining characteristics of being human. This evolutionary milestone not only set us apart from other species but also influenced the development of our muscular system in profound ways.

•The Evolution of Bipedalism

Millions of years ago, our ancestors transitioned from moving on all fours to walking on two legs. This shift was driven by various factors, including the need to cover long distances efficiently, free up the hands for tool use, and adapt to changing environments. As we began to walk upright, our bodies underwent significant changes to support this new mode of locomotion.

•Key Muscles Developed from Walking

1. **Gluteal Muscles (Glutes)**: The gluteal muscles, particularly the gluteus maximus, are among the most prominent muscles developed through walking. These muscles are responsible for stabilizing the pelvis and powering our stride. Over time, they evolved to become larger and stronger, enabling us to walk and run efficiently.

2. **Leg Muscles**: Walking helped develop the muscles of the legs, including the quadriceps, hamstrings, and calves. These muscles work together to propel us forward with each step. The strength and endurance of these muscles were crucial for early humans who needed to travel long distances in search of food and resources.

3. **Core Muscles**: The core muscles, including the abdominals, obliques, and lower back muscles, play a vital role in maintaining balance and stability during walking. As our ancestors began to walk upright, these muscles became more developed to support the spine and prevent injury.

4. **Foot and Ankle Muscles**: Walking also influenced the evolution of the muscles in our feet and ankles. The arches of our feet, supported by various muscles and tendons, act as natural shock absorbers, while the muscles of the ankles provide stability and mobility. This adaptation allowed humans to walk on diverse terrains, from rocky landscapes to soft grasslands.

•The Impact on Human Evolution

The evolution of our muscles from walking not only made us more efficient walkers but also laid the foundation for other forms of movement, such as running and climbing. These adaptations provided a survival advantage, enabling our ancestors to hunt, gather, and migrate across vast areas.

In modern times, walking remains a fundamental exercise that continues to engage and strengthen these evolutionary muscles. Regular walking promotes cardiovascular health, improves posture, and enhances overall mobility—benefits that are deeply rooted in our evolutionary past.

Our muscles evolved to support walking, a movement that has been central to human survival and success. From the powerful glutes to the supportive core, the muscles developed through walking are a testament to our evolutionary journey. By walking regularly, we not only maintain the health of these muscles but also honor the legacy of movement that has shaped who we are today. So, the next time you take a walk, remember that you’re engaging in an activity that’s been essential to human evolution for millions of years.

How To Move Better

Tension built in the muscles takes pressure off the joints, ligaments, and bones and allows the muscles and tendons to work as the support system for the body.

This all sounds ideal, especially if you’re someone suffering from pain and restrictive movement because of pain. However it’s not guaranteed to happen if you do exercises that compress your structure. Squatting with a bar on your back causes compression on you vertebrae, bench pressing limits the range of motion of your shoulder girdle and disconnects the pec muscles from the powerful oblique muscles, deadlifting causes your lower posterior chain to work but neglects the upper and causes your lumbar spine to overwork.

All of these are very common exercises that are prescribed to build strength, but often what you aren’t aware of is it’s at the expense of your joints, spine, bones, and ligaments. The physics behind these movements causes the muscles to load exclusively through one direction of force, whereas in reality, the same muscles are constantly being used through multiple angles of force.

There are a few problems with this way of training. The movements themselves don’t allow the force to be balanced out through other angles, and so while the muscles are being worked, the nearby joints and ligaments are also being strained. The movements also don’t allow other muscle chains to integrate with the targeted muscles, which leads to overuse and fascial disconnection from the rest of the chain. Finally, since the movements only train one force at a time, when you go to use your body in the real world, the muscles aren’t thoroughly prepared to be resilient against the multiple forces acting on it.

These movements do make your muscles stronger, but only within the context of the exercise itself. Once your body is off the bench, or the bar isn’t on top of it, your muscles have not been conditioned to withstand other forces. Additionally your muscles have not been conditioned through integration and all the built in connections are not linked efficiently so muscles are working on their own to help support you. Like you’re in a canoe with a group and you’re the only one doing all the paddling- the group should work together to make the paddling easier and the water more enjoyable. Your muscles should learn to work the same way.

Another point to consider is that the exercises themselves cause strain on the joints, ligaments, and bones from the dysfunctional mechanics during the movement. But the exercises can indirectly affect the joints, ligaments, and bones later down the road, by not offering the right support from your muscles when you move in the real world. In other words, the exercises aren’t preparing your body for reality.

Exercise should be used to build resiliency to life outside of the gym. This concept is one that our trainers always remind our clients of when we teach them exercises that align with this principle. The result is a stronger body, leading to less pain and old injuries being resolved in the process.

SAID Principle

Your body adapts to the demands you constantly place on it. This summarizes the science behind the SAID principle; Specific Adaptation to Imposed Demands. For example, by only doing squats for your lower body, your body adapts to this specific physical demand, but not to other patterns or environments for the lower body, like walking or running.

Another example can be if you sit for extended periods of time, your body will start to change and adapt its structure to the sitting environment that it’s constantly in. This makes it difficult to move correctly when you try to pick up your favorite recreational sport or hiking trail on the weekends, and leads to overuse on certain muscles and eventually pain or injury.

With only so many hours in the day, we all have minimal time to exercise. Which offers a unique opportunity to impose specific demands to counteract the effects of your normal environment. Meaning if you sit a lot, initially you’d want to choose exercises that promote trunk and hip extension, to work in opposition to the spinal kyphosis and hip flexion patterns of sitting. As opposed to sitting all day then getting on a bike and cycling; same pattern/demand as sitting. So nothing improves and your body further adapts your structure to your sitting environment. This can be a problem when you expect your body to perform like it always has.

Circle back to our initial example about squatting and the limits it places on your lower body function. The muscles of the lower body- glutes, quads, hip flexors, calves, plantar fascia, etc.- have all evolved to help the human structure walk and run. It wasn’t until the 1960’s-1970’s that Arnold Schwarzenegger popularized training the muscles outside of their intended functions and with exercise patterns that didn’t replicate the way the muscles worked together to produce human specific movement. A couple decades of consumers training the human body this way (coupled with a more sedentary lifestyle), led to a disassociation with our natural movement and one of the main reasons most people deal with some form of ache, pain, or injury. The body has adapted to exercises that don’t mesh with the way the body actually needs to move.

Whatever demand you put your body through repetitively, intensely, and subconsciously will be what your body is forced to adapt to. Make sure what you’re teaching your body has a carry over to the roots of your human function, so you can continue to move well, without pain, as you age.
