i began to notice a big difference in my upper arms after i started wearing wrist weights. i go to aerobics classes 3 times a week, and once i started wearing weights for them it really made my upper arms alot tighter and firmer.

also, using dumbells to do some moves for your tricep muscles helps. i take a 5kg dumbell (try to increase the weight as you get stronger) and raise it above my head, then whilst keepin the arm lifted you bend at the elbow as if the weight is going down your back, then push back up until you're in the position you started in. then repeat with the other arm. haha, sorry, that sounds really confusing but its the only way i can describe it. you can easily find out some techniques for tricep moves on the web or in books, or by asking someone at your gym.

also pressups are good for toning the arms, and if you place your hands facing in towards each other it targets the tricep muscle
