Our large filler bags for Workout Sandbags are a great addition to your bag.  It allows you to more quickly change the amount of sand inside it to change weight.  Our original design keeps the sand shifting as a whole with the outer bag.  One filler bag holds all the sand for the outer bag.  This gives you a better sandbag training experience.  If you prefer, you can use 2 or 3 filler bags inside the outer bag to divide the load up into segments.  Each filler bag occupies the entire length and width of the outer bag.  The thickness of the filler bag can be adjusted by underfilling it to enable the outer bag to hold 2 or 3 filler bags.  The sand will still shift back and forth the entire length and width of the outer bag. Or, you can take our advice and use one filler bag per outer bag.
