This is where it gets a bit more complicated. This is also where you will really be pushing the idependence of your limbs.
First, we will be playing eighth notes with our feet (hi-hat and bass drum), and triplets with our hands.
Still in the same order as before (hi-hat - snare - bass drum - ride - bass drum - snare - hi-hat). This means you're playing eighth notes and triplets alternating.

Then we'll turn this around: triplets with our feet, eighth notes with our hands.
Very important here is that you keep the distance between the quarter notes (i.e. the tempo) steady.
In the beginning you'll see that you tend to change the tempo when you start playing triplets with one limb, and then change it back again when you go back to quarters and/or eighth notes. You may not even notice, that's why it's advisable to use a metronome with this exercise.
