Custom made, fabric Booty Band, specifically made the way i like them! The fabric increases the strength and quality of the band, with just the right amount of stretch, and perfect to be used for glute activation exercises, or to use when doing hip thrusts and other exercises. The band has added grips inside, to ensure that the band doesn't slide or bunch when you are using it! It is also triple stitched at the seam, to prevent the band from stretching, or ripping with time. This band is a great addition to maximise your gluteus Maximus.
