Short Demo using the Wolverson Hydro Bag.
The Bag is filled with water and then air is pumped in to make the bag taught. It is then an excellent unstable load which forces your core to create the stability. It would be an excellent addition to any home or commercial gym and would be of interest to anybody who uses function in their exercise routine.
just ordered one of these. Looking forward to using it.
