It starts like this:
2 sets of 30
2 sets of 25 (increase weight)
3 sets of 20 (increase weight)
3 sets of 15 (increase weight)
3 sets of 10 (increase weight)
3 sets of 10 (increase weight)
Start over, but with more weight.
It's amazing (when followed properly with a solid diet). My arms won't budge.
I would seriously consider seteroids if (a) they weren't so gosh-darned illegal and (b) I had the money.

That sounds like a toning work out. Power workouts you shouldn't be doing nearly that many reps. To build muscle, I usually do three different workouts for that muscle, and do three sets of six reps. For sustainment I'll do 8 reps, and once I get to be able to do 3x10reps I up to the next weight. (Sometimes it takes a while to get through that plateau. Sometimes you just need to grab that larger weight and throw it up three or four times to break through, then next time you might be ablet o get it)
For my biceps it's:
Bar Curls (Both hands on one bar) I was working my way towards using 90lb bars but since I just spent a month overseas away from the gym I'm back to using 70's.
Dumbbell Curls (Three times - Hammer, Flat, and turn I call them) Hammer is when the weight is more vertical, like you could use it as a hammer. Flat, the back of your hand is facing the ground, and turn, where you start at a hammer and go to flat by the end of the individual rep. There's another kind of curl for dumbbells too that one of my buds showed me, but it's really awkward.
Inverted curlsGrabbing a bar and facing your palms down rather than up.
But don't limit yourself to just direct curls to focus on your biceps. A lot of back exercises need your bicep as a secondary muscle, as it required you to flex your arms and you pull the weight down or back. I.E. Lateral Pull downs. Pull ups and Chin ups. (Chin ups focus on the bicep more, but pull ups still require it). Even a some chest exercises with cables can use the biceps a lot.
Triceps. Pretty much just throw a weight over your head and bend your arm back. You can use one hand with a lighter weight or two and get a pretty decent amount. I do sort of like a reverse curl, where I bend at the waist downward and start with my arm bent 90degrees at the elbow, then extend. Like a curl, just for the other half of the arm. Triceps are a pretty easy muscle to work because they're used for a lot. Bench press (more so with a bar than freeweights) needs a lot of power from the triceps.
But 255 reps for a workout is not going to get you big. It may strengthen that part, or tone if very nicely, but much less reps with much more weight is the way to go to increase muscle mass. Pick an exercise, 3 sets, six reps. And pick enough weight that you can only do it three times, six times each. Then move onto the next exercise, and if you choose a third or fourth and final one.
But everyones different, I'm not physical trainer, this is just from my personal experience
