I sold my old weights they were the middle size weights.  I out grew them.  Be careful you could get hurt if you don't take it slow at first.

I think I should have bought the round bells. These are easily dented and the end of one already broke off at a corner. I need more resistance, too. Handle ends should be plugged. Water drains out but last time in my gym bag and got things wet. Is a bell with more resistance made? Circular bells preferred.
