i was watching a guthrie govan lesson on alternate picking, and he along with many people perfer to use their wrist when doing fast alternate picking. problem with me is, when i go slow, i can use my wrist perfectly fine. as soon as i start getting any type of excellerated speed, i start using my elbow, i can feel my arm tense up, and i can't do it for for more then 10-15 seconds. guthrie says you should be able to do it for a very long time without getting tired, if you use your wrist. how can i train myself to not use my elbow when getting to greater speeds? it seems like it is an automatic reaction my body makes. seems to me like it would be tough to train yourself not to.
