The Glute Bridge aka Hip Bridge or Hip Thrust is a very popular and effective exercise.  This sagittal plane movement is great for targeting the posterior chain.  But what happens when you "super-size" the demand on the posterior hip by driving variable vector forces into the hip from the torso motion on Core-Tex?  A completely unique challenge to the neuro-muscular system for stability and strength gains not found with any other product.  Add a familiar tool you are probably already using to further vary the environment.
