Light/Heavy filler recommendations for medicine balls.
I'd like to make three med balls, weighing 5kg, 10kg, and 20kg. The 10kg will work perfectly with just plain sand, but what would you guys recommend for the 5kg and 20kg to throw into the mix? I'm thinking flour and lead shot, respectively, but I want to see if any of you have better ideas.
Also, do you guys know where I'd find lead shot in bulk? I'll need about 3.5 cups, I figure.
I'll post the volume of materials and the weights obtained once I've made them.
And yes, I'm actually holding that handstand. Get on my level.
