Band Training for the BUTT is simple using this single band technique

To effectively activate the glutes you must get hip extension.
To proprioceptively stimulate hip extension you need surface pressure on the ASIS or anterior hip region.
Band training for the butt is therefore super easy with the band set-up because it accomplishes both of these and people can feel the burn.
