This Sand Disc of GorillaGrip is a round disc, filled with 6 kg of sand and made of the synthetic rubber neoprene. A Sand Disc has a good grip and is therefore perfect to use for a core training. These are trainings to strengthen your back, abdomen and pelvis, your so-called core or center of your body.
We recommend indoor using of the sand discs, because outside on the street Sand Discs wear out more quickly.
