Buff-a-roni

I've been looking everywhere but my dumbbells are nowhere to be found. I want to start using them again because my arms are getting a little jiggly. I've given up on losing weight but I'm thinking about just toning my muscles a bit (ok, don't laugh, I have muscles believe it or not! I'm not all fat, yah know!). I'm not the exercise kind of gal and I don't like to sweat, but if I want to look toned, I have to start somewhere. I'm thinking about buying Kettlebell, it looks like a modified dumbbell and might be more effective than the regular ones, but I'd like to find my old set first before I cough up more money for something I might not get a lot of use out of.
