These exercises were all created to help you obtain independence among your limbs. Mastering these examples, and well as coming up with your own will open a door of possibilities in your playing, no matter what genre. It makes sense - practice what you can't do and you will be able to do more! Repeat all of the exercises until they feel natural, and you can add them to your vocabulary.
Many of these will be very frustrating for those who don't play jazz. It would be a good idea to start without the jazz ride rhythm (which all of these examples show) until you feel comfortable enough to add it.
In this example, you are alternating triplets between your feet, while maintaining the steady Jazz ride. Repeat until comfortable, then try adding triplets on the snare, or play on 2 and 4.
Same as above, but lead with the bass drum.
In this one, you are playing the triplets between the snare and high hat (with your foot). It is assumed you will feather the bass drum with quarter notes since the bass drum is not notated. Repeat.
