This is why we use a mouthpiece during SBM practice.

The Relationship Between SBM and Grip Strength

Many people think that grip strength is simply about the hands or arms.

However, in reality, grip strength is closely related to the neck, posture, and the nervous system.

Clients who practice SBM often maintain or even improve their grip strength—

without consciously trying to train it.

Why does this happen?

In SBM, we focus on:

•⁠  ⁠Creating stability in the lower back

•⁠  ⁠Restoring the natural curve of the neck

By doing so, the nerves that run from the neck to the arms and hands are able to function more smoothly.

When nerve signals flow properly, the body can generate strength more efficiently.

Another important element in SBM is the neck position and biting force

This is why we use a mouthpiece during SBM practice.

By gently biting the mouthpiece—not only during SBM, but also in daily life—

the muscles around the neck are activated and strengthened.

This supports better posture and contributes to stronger, more stable grip strength.

SBM does not train the body in isolated parts.

Instead, it improves overall body structure—

and as a result, grip strength is naturally supported.

These changes may not always be obvious,

but they are quietly and steadily working to support your everyday life.

Let’s continue to value these subtle yet powerful effects

and keep building a body that truly supports us.
