-Striking a wooden board repeatedly with the fingers. Beginning very lightly with a focus on proper structure and alignment of the fingers, slowly increasing the strength of the strikes.
-Hammering nails about half way into a piece of wood and then trying to pull them out with the thumb, index finger, and middle finger. As you get stronger, pound the nails further into the wood, making it more difficult to get a grip.
-With all of these techniques, make sure to quickly treat any cuts and bruises you acquire, and do not try to increase the speed or strength too soon. These take time.
My internal training didn't have anything specific to finger strikes.
The only internal training I've done extensively is Eight Brocades, Marrow Washing, Tendon Exchanging, and Five Organ Breathing. Whether or not these had anything to do with actual conditioning and martial arts training, I can't say for sure, but it certainly can't hurt.
I have heard of several "Internal Techniques" that focus on improving finger strength and projection, but I have not been taught the specifics of these and can only speculate on their effectiveness.
