DIASTASIS & SPLINTING: What's The Difference Between Corseting & ‘Casting’


Ever since the corset has been invented, the pressure has been on for a tiny waist. Many celebrities and public figures have snapped pictures of themselves ‘waist training,’ which involves the use of wearing a modernized corset while working out and in their everyday activities to obtain their ideal waist.

However, a corset will not help strengthen your abdominal muscles nor close your diastasis. In fact, many studies show that corseting or ‘waist training’ weakens the abdominal muscles, decreases circulation, and compresses the organs.

Our splint positions both the abdominal muscles and the connective tissue. The abdominal muscles need to be close together so they move in the right direction when doing the exercises. They need to move front to back. When they are separated with a large diastasis, they move sideways stretching the connective tissue.  Our splint takes the stretch off the “stretched out ” connective tissue so that the connective tissue can heal and the diastasis can begin to close. To be successful with our program means you must keep the connective tissue continuously in a narrow position by wearing the splint all day long, only taking it off for 15 minutes a day to shower/bathe.

The “casting” method, if you will, with our splint is designed to heal a person’s diastasis. Corseting or “waist training” is designed to compress the muscles to mold to a certain shape. But the moment the corset comes off, the muscles are often weak and unsupportive. The moment in our program when a splint comes off is when the connective tissue is healed. Then you’ll not only find your diastasis closed, but fully supported by stronger.
