If you want to be ambidexterous its all about
- incresing nervous enervation of your muscles on your weak side
and teaching your brain to control it (eg. the number of nerves to
that side),
- incresing strength (muscle mass) on that side,
- incresing flexibility of the tendons and ligaments for ease of
use
so try
- simple activities with the other limb first eg. writing,
shaving, holding thigs and picking this up and then work up to
activites such as catching things or juggling etc. Generaly notice
how you use your body aswell and experiment with reversing
sides.
- strech
- lift wieghts with the other side
hope this helps!
