This is a very valid question as some abdominal binders do weaken your muscles. The diastasis rehab splint® will NOT weaken your abdominal muscles. The purpose of the splint is to pull your separated muscles together. Bringing the muscles closer together makes the Tupler Technique® exercises more effective, thus making your abdominals stronger. By bringing the muscles closer together it helps you to feel the muscles whilst you are doing the exercises, and at the same time puts the connective tissue it a better position to heal.
Ultimately closing your diastasis recti is all about healing your connective tissue. Compression garments that bring the belly back to the spine will weaken your muscles as they are doing the work that’s your muscles should be doing. The Tupler Technique® programme strengthens your muscles so that they can do the job themselves.
