In my teens I played a lot of guitar, then started playing piano for a band, and among other things have kind-of neglected my poor guitar for a while. Recently I picked it up again and have started playing again only to discover my fingers are nowhere as strong or fast as they were when I played every day
So, I'm wondering what exercises you guitarists use to build up strength and agility etc. What do you to practice your techniques? Just learn loads of songs? Any effective exercises you stand by? At the moment I'm just doing scales and chord changes to warm up and then learning a few songs.
