I've been practicing on my tapping ability. An example of what I mean by tapping can be viewed here, notice how the right hand hits the strings. 

I'm currently using all four fingers excluding the thumb to tap the guitar. I find my pinky is not as strong as my other fingers when it comes to applying the appropriate strength on the string. What are some exercises I can do to increase my overall finger strength when tapping? More tapping?

As a sidenote, I've noticed that I use the momentum of my forearm to help apply the appropriate pressure on the string I'm trying to hit. If I remove that momentum and only use force created by the movement of my finger the pressure is significantly less. I was hoping these exercises would also help me to not rely on my forearm as much.
