KYSIENN - ProGliders
ProGliders work your core and glute muscles during every move. These
versatile disc-shaped gliders can be placed under your hands or feet
during bodyweight moves to add dynamic movement to your strength
workout. They come in their own carry case and you can take them
anywhere - all you need is floor. These are two sided depending on your
surface - the shiny side is for carpet or rugs, and the black side is used
for tiles, wooden floors, and other hard surfaces.
