I bought some ankle weights the other day so that I can exercise my legs often without having to make time to do it. They're only 2.5 pounds a piece - nothing that will kill me by the end of a waitressing shift, LOL. But I started thinking about how often I should wear them? I know with regular exercise, you're only supposed to do it every other day so that your muscles can grow/heal on the day you don't work out. But then again, they're only tiny little weights, so I don't know if this still applies. Help?
