My endurance is total shit. I get cramps (if thats what you'd call the pain im not sure) in my hand when im playing As I Am. Yeah its that bad. Its basically the 2nd riff that kills me, or the riff where John first plays something mostly different. Could be the Verse, probaby is, but those riff names always confuse me.

This is the maybe Verse or whatever:

G|---------------------------------------------------------|
D|---------------------------------------------------------|
A|-------------4-3-1-4-3-1-4---3----------4-3-1-4-3-1-3--|
E|---------------------------------------------------------|
B|-1--1--1--1----------------------1-1-1------------------|


anyways, now that we got that across, could anyone post some good endurance excercises or link me to some specific ones? please dont put just "oh go to activebass.com". Specific ones that are mostly guranteed to help me would be great, thanks
