Meet the HybridSack: an adjustable water and sand weightlifting bag that helps you get a good workout anywhere. It can be filled with 77lbs of water or 120lbs of sand. It has a bunch of handles, so you can perform all kinds of exercises with it (deadlift, row, squad, press, curls, …).
This adjustable fitness weight can be used indoors and outside. It is water sealed, so you won’t have to deal with any leak. Once done, you can fold the bag to take it with you anywhere.
