Alternate picking exercise

Heres a great little exercise. Take the following chord patterns.

E|-------10--10----7---7---------------
B|-------9---8-----8---9---------------
G|-------8---9-----9---8---------------
D|-------7---7-----10--10--------------
A|----------------------------------------
E|----------------------------------------

As you can see, each chord change involves either swapping your index and pinkie fingers or your middle and ring fingers.

You can start by just practicing the chords but once you can change easily, try picking D U D U through the chords as you change. It's a great workout for your alternative picking technique! You can try other picking patterns such as sweeping all downstrokes, upstrokes, U D U D etc.
