I try to practice every day, but sometimes i just don't get it in. Most of the time, I get to practice about four or five days a week. Then there's the day I take lessons for an hour or so. I usually practice about an hour and a half. For the first 30 minutes, I do pad work. The first ten, I do an exercise where you play like you would a tympany - palms up - and use only the fingers to push the sticks, no wrist motion. This has helped me build my finger strength a lot! My doubles are better for it for sure. I play for one minute straight on each hand seperately, then eight counts alternating hands, then six, four, three, doubles, then singles. I usually stretch after this. Then I spend the next ten minutes or so doing snare solos I've learned and learning new ones when I get a handle on the older ones. The last of this time, I do rudiments. I usually do some singles, doubles, diddles, and ratamacues just about every day. I also spot-check the rest one or two a day.
For the hour, I go onto the kit, usually doing a couple of snare solos first, then I might add a rudiment or two into a groove. Right now I'm working from three different books; one on rock shuffles, one on rock fills, and the other is the Turn It Up and Lay It Down book. I spend about 15 minutes working out of each one. Then I play grooves I've worked on with the bass tracks in the Turn It Up book. If there's any time left, I just jam a bit, practice adding fills from the rock fill book to some grooves I already know. Sometimes I'll play along with a song or two. I also use a metronome, but not as much as I should at times. My drum instructor helps keep me accountable. He expects some progress when lesson time rolls around.
