What do you guys think of this? Seems a little pricey, but I would like to add it to my equipment. Kinda like a clubbell or kettlebell only safer.
Pretty sure there's a big thread about this in the strength sports forum. Might wanna run a search for it.
make your own out of a tyre inner tube (you might have to order it online from an off-road tyre place) sand and maybe straps for handles
