These are some alternate picking torture tests that I use for warmup and practice. I picked these up along the way from lesson material by Mark Whitfield, Jimmy Bruno, and others.
These clips are neither very fast nor very accurate, but you may want to use these or similar for your exercises.
Diatonic 7th Arpeggios:
Stairstep Scales:
I do very similar scale exercises to warmup before I play, when I can remember that is.
If I ever gig again I’ll be making sure I do warmups like these though as I had some bad gigs where I literally picked up my guitar and started playing after a week of not playing.
In a typical pub gig situation for me though we would normally have some kind of sound check, where we can play thru one song at least and maybe do some warmups, but then there’s normally some hours of drinking and chaos before we get onto the “stage”. So finding time and space to warmup can be challenging.
