first off you shouldn;t just work your arms, u need to work your entire body other wise it will be unbalanced, so i would do back and chest execrises with the arm ones, and also i would add forarms to the work out
Shoulders:
1. lateral raise (dumb bells raised to the side)
2. front raises(dumb bells raised straight in front of you)
3. miltary press
Biceps:
1. Hammer curl (dumb bell held with palms facing in, and dumbbell perpindicular to the floor)
2. Dumb curl (dumb bell held with palms faceing up) (or us your curl bar(which should be a cambered bar)
3. if u have a inclined bench, incline dumb bell curl(start with dumb bell held with palrm facing in, and end with palms facing up, its the first two combined but you sitting on an incline bench)
Triceps:
1. Skull crushers (cambered bar, or dumbbell, hold weight directly above your chest, tri's perindicular to the floor, then bring weight back to your forhead(make sure you use a lighter weight) and then bring it back up)
2. Dips (use a bench, hands should be shoulder width apart on bench, dip down till your tri's man a 90 degree angle, then back up
3. if you have a pulley system in your gym, do the underhand pull down(grab pulley with palm facing up, this is for each side by its self, pull down till arm is exteneded, do not bend or twist your arm/body to get weight down, u could injure your shoulder
4. if you do not have a pully system, do tricep overhead extenstion. (Sit with back straight on a bench, better if it has a back rest, take dumbbell grab the one end of the weight, so it hangs perpendular to the floor, lowe the weight behind your head while keeping your tri's straight and perpendicular to the floor, and keep your tri's close to your ears, as to keep good form.
5. you can also do back close griped benchpress (lye on the bench, hold the bar with a close grip expect switch it, instead of your palms facing away from you, turn them so they face you. Lower ther bar down untill it is close to your chest(but not touching) when bringing the bar down, a good way to tell if you should stop is when your arms make a 90 angle, your tri's on the bench flat and your forarms straight up, then push the bar up. make sure u do this very slow, otherwise it could throw your shoulders out of line.
6. tricep iso (ly on the bench, take a light weight dumbbell, hold your arm straight out infront of you while lying on the bench your palm should be facing away from your and dumb bell parellel to where you would bring the bar down for a bench press, take your other hand and place it on the extened arms elbow. then slower lower the weight down to your chest using your support arm to steady the arm and to keep the tricep vertical. do not bend your arm inward(will mess up your shoulder) lower the weight with the support of the free hand, then bring it back up)
I will write more aobut the forarms, back , and chest if you need it
