Here is a summary of how to train yourself to be ambidextrous:

• Practice with your non-dominant hand by performing small, everyday tasks such as writing your name, brushing your teeth, opening doors, or cleaning.
• Strengthen your non-dominant hand and fingers by lifting light weights or using a grip exerciser. Juggling or tossing a ball can also improve hand-eye coordination.
• Use your non-dominant hand to control the computer mouse to increase dexterity.
• When writing, hold a pen with your non-dominant hand as you would with your dominant hand, avoiding a tight grip.
• Trace the alphabet with your non-dominant hand, then move on to writing letters and simple shapes without tracing.
• Practice writing your name and full sentences daily to improve your skills.
• Consistency is key; practice these techniques daily for at least a month to build the habit.
• Consider tying your dominant hand behind your back to force yourself to use your non-dominant hand.
