I found this guitar shred exercise as a kid in a guitar magazine. Full credit must go to Gary Hoey for it. This is great because it is only going to take you six minutes a day to practice. I remember reading the Steve Vai 10 hour guitar workout and he mentioned that he would practice trills for an hour every other day. So we can easily do six minutes a day everyday.
Step One: Put your 1st finger on the 1st string 5th fret. Using your 1st and 2nd finger, play the 5th and 6th frets over and over using hammer ons and pull offs only. Do this for 1 minute.
Step Two: repeat this exercise using the following finger groups: 1-3,1-4,2-3,2-4,3-4. Do each group for one minute. That’s only six minutes a day. You may find that using the 3rd and 4th fingers only extremely hard at first. Don’t give up! In a few days you will have it.
Also note that the 1st finger covers the 5th fret, 2nd on the 6th, third on the 7th, and 4th on the 8th. You should change this up eventually but start this way.
For all of you fellow Guitar Burning Speed users, this 6 minutes makes a great addition to the 20 minutes a day you already put in. All this guitar shred and you are still under 30 minutes!
