i think first you have to differenciate between equally-skilled and
equally-strong limbs. then we have do differenciate between an average
person and a juggler.
then i would like to say that my experience with strenght training a few
years ago was that equally-strong limbs are nearly possible. My experience
with juggling in generel and 2 Devilstick Juggling in special is that two
equally skilled hands are nearly impossible.
so let愀 start with: why should an average human should have equally
strong limbs ?
The only thing i can think about here are muscular disbalances becouse
behind a weak left hand there propably a weak left shoulder, a weaker left
part of the latissimus and so... i guess this can lead to a variety of
injurys but i惴 not an expert on this so maybe im wrong (i don愒 think so)
so what would be the benefits for a non juggler to have equally skilled
limbs ?
There might be some benefit to you愉 brain but so little it would be hard
to verify and there are better ways to practise your brain.
One of the real benefits is the ability to perform tasks with your weak
hand while youre other hand is, for example, holding something or doing a
different or related task (just think of locking a door while holding a
lot of stuff in your other hand)
I惴 sure there are some other points but they don愒 spring to my mind now
so let愀 move on to a juggler.
Equally strong limbs:
Same as above, injurys becouse of muscular dysbalance (in this case +
excessive juggling without proper technique, stretching, strenght training
and so on...)
Dysbalances in Patterns, for example left throws being slightly lower,
endurance always ending with a drop out of the same hand
Style, all highthrows out of the same hand everytime, starting all
patterns with the same hand...
for equally skilled limbs i just want to say: style and beauty
one of the most depressing moments in my juggling live was when after one
of my first (devilstick) performences someone came to me and asked:" are
you left handed ? " I was and i still am and since then i惴 working
towards not letting people now which hand is my favourite when im juggling.
i guess that was all i wanted to say for now
