It’s common for individuals to be naturally stiff or experience a decline in body flexibility with age. Here, flexibility refers to the softness of muscles that determines the range of motion.
Can you touch your toes with your knees straight? Can you reach the itchy spot on your back? Can you stand, bend backward, and see what’s behind you? Take a moment to check now while reading this post. If any of these apply to you, the likelihood that you are currently or will experience pain in your body is extremely high.

It is said that individuals with less flexibility experience increased strain in the same movements compared to flexible individuals. For instance, if we think in terms of power, in an arm wrestling match between a champion and an amateur, the amateur exerts 100% of their strength, while the champion only needs 10%. This concept applies to daily activities such as leaning forward to do dishes or cleaning, daily walking, and sitting, where the level of flexibility influences the strain experienced in various situations.

Now, why does flexibility decrease? The answer is simple. One reason is attributed to the reduction in muscle mass due to aging. Therefore, maintaining flexibility over time requires regular and moderate exercise. Another reason is that excessive strain on certain muscles due to spinal misalignment can lead to a decrease in flexibility. Surprisingly, the latter accounts for the majority of cases, and many individuals, even in their youth, may have stiff bodies. Improving spinal misalignment through Seitai contributes to enhanced flexibility, leading to fundamental pain improvement and the creation of a body less prone to recurrence.
