Detailed Answer
Drills isolate specific movements, building muscle memory faster than full-text typing. For example, drilling 'ftg ftg ftg' trains the left index finger to move from F to T to G. Drills also expose weak keys and finger combinations (e.g., pinky exercises: 'qa qa qa'). They eliminate cognitive load – you don't think about spelling or content, only finger motion. Effective drills: home row only, top row, bottom row, common digraphs ('th', 'he', 'in'), and alternating hands ('jump jump'). Use Keybr.com (generates drill words based on your weak keys) or custom spreadsheets. Spend 5–10 minutes on drills before free typing each session. Results appear in 2 weeks.
