I need a new/ modified routine!

I'm 15 y/o female
I go to the gym 3-4 days a week.
My main focuses are cardio, legs [specifically thighs and calves], arms [mainly biceps and triceps, just slightly more toned than they currently are. ] and, what I'm really have troubles with-my abs.
 
I really want to focus on lower abs the most, I'm having no trouble with my upper abs.
 
I've been going since about november [2 times a week] and 3-4 times a week since February.
 
I don't currently have a routine, and work most of my muscles everyday.

For your lower abs, you could do leg raises, hanging leg raises and leg scissors.

By the way, are you looking to add muscle, get toned, or just be fit?

Coz i was looking at what you said was your routine, and you said you trained almost all bodyparts everyday. So I was just wondering.
