These are the wrist weights I use. I admit I use them only for micro-loading my barbell. You can't tell on the picture, but they have this velcro fastener and tightened all the way down it fits really snug on the end of a barbell. They are one pound each, and they are soft *iron* so no leaking of sand, and they are very flexible. I have lots of extra flex iron pieces, they are 1/2 pound each and I can micro-load with those too by slipping in another one and velcro that down, so you get the idea. My husband gets annoyed with me. He'll say something like.....just jump up a pound already!
