Step 3Active Training
iImage Information

Some activities may not be eligible, for one reason or another, for passive training. For example, writing may not, at first, be legible when you use your non-dominant hand. For things like work or school, turning in a report that looks like it was scrawled out by a kindergartener is not an option. In these cases, active training is necessary. Every day, take the time to transcribe a moderately sized block of text with your non-dominant hand. The lyrics of a song by your favorite band, or part of a script from a play or movie, or a passage from a book. This should keep things interesting and maybe give you a better understanding of the text in question. If you like, you can buy an inexpensive handwriting primer at virtually any bookstore or department store.
Another technique to try is training with larger objects, perhaps training your non-dominant hand with sports such as tennis, racquetball, ping-pong, bowling, fencing, riflery, playing a musical instrument or, if you have one, a Nintendo Wii. Sadly, certain articles of sporting equipment, such as fencing foils and golf clubs, are not as ambidextrous as you aspire to be, and you'll have to get different handles, at least.
