This video shows you such a good exercise for warming up your arms and fingers, ready for all that shred action. It loosens up your muscles and helps you get passed the ‘cramping up’ point when you are especially playing fast licks, solos and runs.
The best thing about it is that you don’t even need to pick up your guitar to do it! You can do it on your way home, your way to rehearsals or your way to the gig.
Give it a go and I promise you, after 20mins of this, your fingers will be flying!!
