DIY!
Ever noticed how expensive store-bought weight balls are? They're just heavy spheres, right? Well, guess what? You can make one yourself. Just grab a basketball, pop a hole in it, and fill it with sand using a funnel.
Use your bathroom scale to check the weight for precision. Once you reach the intended weight, seal the hole, and you've got a homemade weight ball. To skip the shenanigans, all you need is an $8 funnel!
