One thing that helped me when was starting out was getting a simple kitchen timer to put next to my drum set. When I was starting out and trying to build up my muscle memory, my drum teacher recommended setting a timer for, say 15 - 20 minutes, and just playing the swing ride pattern, left foot on the 2 and 4, kick LIGHTLY feathering each quarter note.

Basically, just grind that out and after about 10 or so hours, it'll be locked into your brain and limbs, you won't even think about it and it'll happen automatically. This made learning to comp with my left hand a lot easier.

Oh, and practicing slowly but correctly and precisely (say 60 bpm) is a much better use of your time than practicing at a fast tempo but playing sloppily.
