Five minutes of these before you play loosens the hands, builds independence and strength, and dramatically improves accuracy. Do them slowly with a metronome — speed is a side effect of control, never the goal.
The single best warm-up: one finger per fret, ascending across all six strings, then move up a fret and come back. Builds finger independence and left/right-hand sync.
Keep every finger close to the strings. Pick each note with strict alternate picking (down-up-down-up). Start at 60 bpm, one note per click.
Trains the weakest finger pairs. Awkward at first — that awkwardness is exactly the weakness you're fixing.
Two minutes daily on this does more for clean chords and fast runs than almost anything else.
The "one-minute changes" drill: pick two chords, switch back and forth for 60 seconds, count clean changes, beat your number next time.
Em ↔ A, G ↔ C, A ↔ D. Start with pairs that share a finger anchor to keep one finger planted.
Look for a "pivot finger" that stays on the same string/fret between the two chords, and don't lift it. Your hand moves less, changes get faster.
Aim for 30+ clean changes a minute before adding a strum. Use the metronome and change on beat 1.
Gently open and close the fists, stretch each finger back, and rotate the wrists. Cold hands play badly and injure more easily — a minute of movement helps.
Sore fingertips are normal for beginners and build calluses. Sharp joint or wrist pain is not — stop, rest, and lower your effort. Tension is the enemy of both speed and health.
