Dumbbell Exercise?
 

Can someone send me to a site that has a list of various exercises which can be performed with dumbbells which ALSO highlights which muscle groups should be worked for that particular exercise?

Lumpy -- I'm not sure if this is what you mean -- but check out these two sites that have little videos of exercises for various body parts, some with dumbells: http://www.fitsite.com/anatomy.cfm (click on a body part for a list of exercises -- the dumbbell ones say "DB") and http://www.exrx.net/Lists/Directory.html (on the righthand side of the page, click a muscle under "exercises" and it will list exercises by equipment type, like cables, DBs etc).

Edited to fix the second link.

You can also look at Krista's page at http://www.stumptuous.com/weights.html.
She's got an entire workout for dumbbells called "all dumbbells! all the time!" in her kompendium of workout routines. Every exercise is explained - with information about target muscles, synergists and stabilizers. It's very good.

Meg, that first link was exactly what I needed. Thank you.

Wow Mette, your site is great too. I've already learned a lot. Thanks!

Heyyyy cool!!! Thanks so much!!! I know there were a couple good ones on about.com but I've wiped my hard drive and lost all my links!! Thanks again girls!!
