How to use your arms for better momentum

Walking is one of the most effective and simple forms of physical activity. Though walking may look simple, the mechanics behind it are far more complex. While walking, people swing their arms. Ever wondered why we do this? Swinging your arms can significantly impact your walking efficiency, speed, and has other health benefits. Arm movement not only boosts momentum but also improves balance, posture, and overall energy efficiency. Let’s understand how the power of arm swing can transform a daily stroll into a more effective exercise.

Arm swing matters

Most of us swing our arms when we walk or run. Most importantly, our arms and legs are in sync with each other. This is because the human body is designed to move in a coordinated manner. And the arm swing is there to counterbalance leg movement. When you step forward with your right leg, your left arm naturally swings forward to maintain balance and reduce rotational forces on the torso. This natural rhythm minimizes energy expenditure and stabilizes the body.

A study published in 2014 in The Journal of Experimental Biology found that swinging arms save energy. When it comes to running, swinging arms counterbalance the momentum of a person's legs, providing stability to the runner. The study observed 13 participants and compared the energy cost of running in four different positions. They looked at the oxygen consumption and carbon dioxide production while running. The researchers found that swinging your arms uses 3% less energy than keeping your hands behind your back, 9% less energy than folding your arms over your chest, and 13% less energy than running with your hands above your head.

The study notes that the muscular power used while holding the arms in unusual positions may contribute to some of the extra energy cost.

“Overall, we believe that our comprehensive approach to testing our running arm swing hypothesis provides the most conclusive evidence to date that arm swing provides a metabolic benefit during human running,” the study author concluded.

No doubt, swinging arms while walking and running can offer some benefits. But how do you do it the right way? Well, being mindful is important. Focus on the natural rhythm of your arms and legs. For best results, avoid carrying objects like phones or bags in your hands, which can disrupt the swing.

Incorporating proper arm swing into your walking routine is a simple yet powerful way to improve efficiency, burn more calories, and also improve overall health. Next time you hit the pavement, let your arms lead the way.

Along with boosting momentum, arm swing also engages the upper body. Consider it as a low-impact way to tone muscles in the arms, shoulders, and core. You can also burn more calories than your regular walk while swinging your arms. Think of it as a more effective full-body workout. Arm swing also improves posture, as it engages the core and keeps the torso upright, and can reduce strain on the lower back.
