Most people don’t realize it, but the human body is designed to be asymmetrical. If you’ve ever caught yourself standing with more weight on your right leg or striking that “sassy” stance with your hip popped out, you’re not broken, you’re just human. There’s actually a deeper neurological and anatomical reason for this, and it all starts in the brain.
Our brains are split into two hemispheres, and each side controls the opposite side of the body. The left side of the brain controls the right side of the body, and it’s often considered the more primitive or reptilian side. It’s packed with cortical neurons, which gives it an edge when it comes to timing, sequencing, and motor control. This is a big reason why most people are right-handed and why things like speech, language, and comprehension tend to live in the left hemisphere. It’s structured, efficient, and really good at helping us plan and execute movement.
The right side of the brain is a little different. It controls the left side of the body and is where our creativity, emotional intelligence, and spatial awareness live. It helps us recognize faces, remember places, and process the world in a more abstract way. So while the left brain is busy organizing movement and speech, the right brain gives us the ability to interpret, connect, and create. Both sides are doing very different jobs, and that built-in imbalance actually helps us function better.
This natural asymmetry shows up in our internal anatomy too. The right side of your body carries more weight, thanks to organs like the liver, gallbladder, and most of the colon sitting over there. That extra mass shifts us slightly to the right. On top of that, the diaphragm tends to expand more easily on the left side, which creates pressure that nudges us even further to the right. Even your ribs, lungs, and the way your spine curves all contribute to this right-side bias. It’s not random. It’s built in.
So when people talk about fixing posture or trying to make both sides of the body perfectly even, they’re kind of missing the point. We aren’t meant to be symmetrical. That’s not the goal. At AIM Athletic, whether we’re working with hockey players, guiding members through active rehab, or leading small group strength training, we build programs that work with your natural asymmetries. We’re not chasing perfection on both sides. We’re chasing better movement, smarter strength, and long-term progress.
Your body isn’t broken. It’s just built this way. And when you train with that in mind, everything starts to feel and move a whole lot better.
You've got the info, now it's time to take AIM!
