Work on increasing your hand cordination, and strength.
Warm-Up
Do a couple of 8th notes, like a dozen, until it's a muscle memory and you don't have to think. That is easy and shouldn't be hard. Then work on 16th notes, do the same, only longer.
After that's into muscle memory, work on 'paradiddles' they go like this:
(right paradiddle)Right, Left, Right, Right (Left paradiddle) Left, Right, Left, Left.
At first do them as basic quater notes, then work at 8th notes. Keep working at 8th notes till your sick of them, and you'll thank yourself later on. After that work on going as fast as you can while still in control.
This was the best way of improve cordination for me. Hope it does the same for you. This also takes time, i've been playing the drums for around 8 years, and it took me around 2 months at first to get this solid down without having to think about it.
EDIT:
Stepping It Up A Notch
Try doing flams. Flams are hitting one stick down, while consecutivly hitting the other one down afterwards. It's hard to explain till you've actually seen it done. Ask a friend or a person you know that plays drums how to do it.
Anyway, start off with you dominate hand hitting down first (Ex. right hand) and fallow with your left hand right after. before you start make sure your left hand is higher then your right, it should give you the proper timing. Do this slowly, then switch to your weaker hand hitting down first. Then repeat while doin paradiddles (above).
This is the most i can come up with for now, i'll edit with more later
I started with a practice pad. I was using chopsticks and the couch so my parents decided to get me drumming lessons as well as a practice pad and a pair of drum sticks. Get a metronome. It will help you keep your rythem and help you when you get to triplets. I only had a few lessons. The paradiddle is very goos practice. If you have a friend that has a drum set ask if you can mess around on it and see if they will show you a few things. I got an electronic drum set at sams club for half the price they usually ask at music stores. I stoped for a while, but recently my friend brought her bass guitar and amp over so i could plug it into the amp and play it, just to find out that I am actually pretty good when I though I was terrible. I'm still a newbie.
