Like it or not, playing the guitar is an athletic endeavor. Just like any sport or exercise, it can take a bit of playing time before you reach your “zone,” so just as a runner stretches before sprinting, a guitarist should warm up before delving into practice or performance. Between strumming, fretting, and hammering-on also lies the possibility for injury, a fact many guitarists disregard until they figure it out the hard way—the fretting-hand fingers and wrist are particularly susceptible to repetitive strain injuries.
