I'm wondering how useful they are for working your arm muscles, biceps etc.
I'm a complete newbie, and I have a 15lbs one lying around. If I worked my arms with them, say every 2 days, would that show results?
The reason I ask is because I heard that dumbbells and machines should only be used to "tone" your muscles and not actually for growing them?
Thanks for any insights.
