A 200lb sandbag filled to 150lbs is NOT the same as a 150lb sandbag.
Underfilling changes the shape of the bag, how much the weight moves around, and ultimately how it feels to lift, so there’s a point where underfilling becomes too much.
In Part 2 of our Sandbag FAQ, we cover how much you can underfill a bag, how full it should be, why underfilled bags feel different, and what you should actually be filling your sandbags with.
