Please take this anywhere it'll make life easier for all the bros.
I'll start w/ something that has had a HUGE effect on my playing comfort.
WARMUP for FINGER AGILITY.
* Hold all 4 fingers together on each hand.
* Curve fingers & slowly rotate the TIP of each thumb around the TIPS of all 4 fingers as they are held together, moving from index finger to pinky on each hand.
* Do 10 revs & then reverse direction for 10 revs. Keep this up for a few minutes.
What this does is "loosens" the tendons across the back of the hand & frees up finger motion.
Give it a chance & try it prior to play & @ the start of a gig set.
Keeping your hands "in the pocket" feels pretty "groovy" as well
