Hi,
I'm 14 5'5 and 120 pounds. I'm looking to gain lean muscle without too much fat. I've been reading up a bit, and here is the workout routine I've been planning on starting. Is it any good?

Day1 - Full body workout
Day2- Jogging 20 mins
Day3- Full body workout
Day4- Jogging 20 mins
Day5- Full body workout
Day6- Break
Day7- Jogging 20 mins

here's my Full body workout I've put together:

Military Press- 10reps x 2sets
Leg Press- 10 reps x 3 sets
Lat Pull Down - 10 reps x 3 sets
Calf Raise- 10 reps x 3 sets
Dips- 12 reps x 2 sets
Seated Press- 10 reps x 2 sets
Crunches- 12reps x 2 sets
Leglifts- 12reps x 2 sets
Pec Fly- 10 reps x 2 sets
Arm Curl- 10 reps x 2 sets
Wrist Curl barbell (palm down)- 10 reps x 2 sets
Wrist Curl barbell (palm up)- 10 reps x 1 set
Hamstring Curl- 10 reps x 2 sets.
Tricep Pull down- 10 reps x 3 sets.
Knee Extensor- 10reps x 3 sets
Bent Over Rows- 10 reps x 2 sets

Roughly my daily food intake has currently been:
1800 - calories
125 g. -protein
32 g. - fat
253 g. - carbs

So, is this a good routine for gaining lean muscle and not too much fat?

errr.. first of all. 1800 cals, i dont know what you're maintence is, but im pretty sure you need to eat more.

As for you're routine, read around on some of the other fullbody threads around here. We give the same recommendationes to just about everyone.

uh yeah, ya need to eat more kid!

how much more? I was checking calculators and all that and between 1700-2200 was the recommended amount of calories it said I should be eating.
I'll do a bit more research for my diet later on tonight, right now I generally just want advice on my workout routine.

And I've read a few of the threads for full body workout routines, but most of them were people of different age groups, weight, etc. and had different goals then me.
So is my workout ok?

You want to gain muscle, you got a pretty normal goal.
You're workout is not ok, too much isolation. How much time does that take?
Squats
Deadlifts
Rows
Pullups
Military press

thats a pretty basic fullbody routine.

I'm not sure how much time it would take because I haven't started it yet, it was just a workout I was planning on starting.

Here has been my current routine for the past month or so:

Biceps: 3x12 dumbbell curls
Back: 3x12 deadlifts, 3x12 barbell row, 3x20-25 shrugs, pullups
Triceps: 3x12 seated tricep extensions
Chest: 3x12 bench press, 3x12 dumbbell press
Shoulders: 3x12 dumbbell military press, 3x12 dumbbell raises, 3x12 side dumbbell raises
Forearms: 3x12 reverse forearm curls, 3x12 forearm curls
Legs: 3x12 leg extensions, 3x12 hamstring curls

been using as much weight as I can to complete the sets, either to failure or almost failing, takes about an hour and a halfish.

And I don't know, you're workout routine just doesn't look like I'd gain a lot. I havn't seen much results with my current routine, so I dunno I just don't see me gaining anything with the workout you just provided.

Ugh, why does it have to be so complicated...

that were exactly my thoughts when i saw a propper fullbody routine for the first time. Those exersices will work you're entire body. Do you even know these exersices, have you tried them before?

Yes, I've included them all in my current workout (see above) excluding squats. I'll be honest, I'm a bit afraid when it comes to squats. I don't have a spotter and I'm afraid of doing some damage because of improper form.
But I'll of course get over that fear if it's a necessary exercise, I just want to see some lean muscle gain.

Can you give me any advice as to how many sets, reps, etc. I should be doing? I should still go to failure right?

you dont have to go to faliure all the time. As for squats, does you're gyms rack have safteypins? that the bar will hit if it goes low enough so it wont land on top of you?
Squats and deadlifts are nessecary exersices. To learn them, ask a PT or watch some videos and read some articles about them on the net.

10 character limit.

Ok but generally for each exercise 3x12, failure/almost failure should be good?

And I'm not sure about the safety pins, I haven't really checked it out... I will make sure to tomorrow, and I'll ask someone who works there to just show me through one rep to see if I'm doing it properly (I've watched videos and have a general idea of how it's done, but I'll ask just to be sure)

Thanks for all your help.
