This is a typical practice session of mine. I'm concentrating on my feet in this practice. It takes me 1/2 hour to get from 140 BPM TRIPLET OR TRIPLET RUFFS to 190 BPM triplets and triplet RUFFS. You may need to start at a slower speed or you may be able to start at a faster speed. Just take it easy. I didn't learn this in one week. I've been practicing double bass seriously for the past 5 years.

You will also hear the hihat. I play a SHUFFLErhythm with my left hand on the closed hihat. This helps to keep the triplet ruffs TRIPLET RUFFS. Through these WARMUPS remember that I'm just warming up here. These things don't have to be perfect. When I play in a live performance situation, I would only play these at a comfortable speed and very clean. (without errors)
