I agree, invest in some dumbells, especially the adjustable kind! Push ups are great as well!

Here are some links to how to work your biceps, triceps and shoulders.

Also, read this to learn more about how often to train your muscles. You need to give your body time to rest between sessions, so don't work the same muscles every day.

Stick with it! It takes time, but in three months you will have completely new looking arms!!! It works, and not only will your arms be less jiggly, but you will be burning more calories than ever before (takes more calories to keep the muscle fit and trim than it takes to support a fat cell!)

Your arms might be sore after you work them the first time, but they will get used to it quickly!
I think I started lifting weights again (dumbells) about two months ago. When I started, I had a TON of fat under my triceps. It was so discouraging, I felt like crying every time I saw it!!! Today I am happy to report that the fat deposit is nearly history! My arms are looking really buff, slim, defined, healthy, etc. I know in another month they will look even better. I love quick results, so it was hard to stick with it, but I knew if I did I would really be happy in the long run. So give it a shot and keep at it!!!!
