8 killer arm workouts you can do virtually anywhere

Having strong arms is no easy feat.

From your triceps to your palms, there's a lot of muscles to put to work.

Now that we've tackled stretching and leg exercises, we asked New York University physical-therapy professor Marilyn Moffat, who also wrote the book "Age Defying Fitness," to help guide these tips.

To keep things simple, she gave us the best exercises for your arms that you can use virtually anywhere with minimal equipment. No weights required.

These workouts are great on their own but they're even better in combination, so feel free to mix and match. Repeat or hold each exercise until it gets to be too much, building up at your own pace. And remember: If you have any unusual pain or problems with the exercises, please stop doing them and consult a physical therapist.
