working on breaking old habits I realized my finger independance sucks. For example when I do a bend with any finger, my other fingers do a bending motion with it which makes it harder to bend and fret something faster.

Also I saw this thing on a site that tests your finge rindependance where you have your left palm facing you and try to bend each finger to your palm without your other fingers moving at all. And I can't do it at all with any finger!

So what can I do to improve my finger independance?
