Alright, here's my story.
I started lifting weights almost exactly 1 year ago. I was 16, weighed 140, was pretty small, and couldn't lift crap. I had played around with lifting for a couple years before, but I never stuck to anything. I finally decied to start up a regular routine, and I have kep to it for a year so far.
I started lifting everyother day, and it worked for a little while. After some time I had reached a plateau, so I read up on the net, and knew I needed to lift less and rest more. So I cut it back to once every 3 or 4 days. That worked for a while, and then again I hit a plateau.
The last 2 months or so, I've tried lifting only once a week; every sunday. I get a good 50 minute or so workout, doing upper body only, and I feel sore for about 4 days after. I'm kind of obsessed with lifting weights, and my biggest fear is overtraining and losing muscle, so I wait a couple days after my muscles start feeling better.
I'm to the point now though, were I think I'm really only maintaining, and I'm not really making very big gains anymore. Should I try lifting every 5 days or so? I'm pretty sure I need to lift a little more often, but I'm just so afraid to overdo it.
My routine is bench, curls, forearm curls, and reverse forearm curls. It's not much, as I only lift in my basement, but I'm not worried about my lower body as I'm a sprinter and long jumper in track, and have an amazing vertical for my height (5' 9")
I have made huge gains since I first started. I started with benching about 3 sets, of only 100 lbs, and my max was probably like 120. I curled about 50 lbs. I'm to the point now where I can bench 155 for about 10 reps easy, and even after I do a hard bench workout of about 25 reps, I can still get 175 up. My max now is somewhere between 190 - 200, not sure though I haven't maxed out in a while. I now curl 3 sets with 90 lbs, and 2 with 95. Max while keeping good form is probably 105 or somewhere in there.
I'm naturally skinny, althought I do have some meat on my bones. I've notice huge gains in my arms since I started lifting, and at first had literally no pecs at all, while I now have great ripped pecs.
Like I said, I've made big gains, but I don't feel like I'm as far as I should be by now, and I need some serious help find tuning my routine, and figuring out how often I should lift.
