I've been trying to fix my alternate picking technique recently, and I can't really tell if I'm doing the right thing. When I practice my alternate picking exercises for a long time, where should I start to feel tired with proper technique. Right now I get tired in my forearm, but I don't know if that means I'm doing something wrong. Any advice is appreciated!
I don't know if there is a set in stone universal answer, as it would depend on a variety of factors. But that is where I use to get tired.
Good question. I don't actually remember ever feeling physically tired when practicing any guitar technique, but that might not apply to everyone. If your forearm is getting tired, perhaps try to relax it when picking a little?
I've never felt fatigue in my arms or hands. You're probably too tense. Relax.
