If you can play 8th and 16th note triplets, you can nail this fill with just a little practice. The most difficult thing about playing it will most likely be getting used to playing triplets across two different drums.
This lesson focuses on a sixteenth-note triplet fill that's easy to grasp, but because of the syncopated snare strokes that really stand out, this groove sounds much more difficult than it actually is. Of course, playing difficult-sounding drum fills shouldn't be your main goal. This drum fill has a lot of tasteful applications.
This lesson explores some ideas for half-measure triplet tom fills. All of these patterns use alternating sticking (i.e. R L R L, etc.). Make sure you pop the accent on beat 4 to make these grooves rock. You can also explore other dynamics such as a crescendo to bring these to life.
