Seitoushin

Seitoushin (Pain Adjustment Needles) are training tools utilized in Ten Shitai. Merely inserting them doesn’t cause pain, but they’re inserted in such a way that pain will shoot through your body when you overuse the muscle in the places where they’ve been inserted. In a manner of speaking the muscles in the part where the needles are inserted are muscles that will actually lower the human body’s potential efficiency if you rely on them too heavily. In other words, by moving so that you don’t feel any pain in your needled state, you will be able to simultaneously learn ideal body control and strengthen the muscles that are truly necessary.
