This is a coordination exercise written in 4/4. The bass drum is in groups of 2, snare drum in groups of 5 (phrased 1 2,1 2 3), and ride cymbal accenting groups of 3. Not only is this good to strengthen coordination in your drum set playing, but this can create rhythmic tension in your songs and solos.
It can be helpful to build it up one limb at a time without the accents at first. When you have it down, try placing the accents on different parts of the kit.
