One leg stronger than the other...

I don't think that your issue is uncommon.  I have noticed over the last year or so that the leg opposite of my throwing arm is stronger.  In fact I sometimes find myself rocking to that leg when I squat. 

I think that throwing has at least a part in the reason.  If you think about it, the leg opposite your throwing arm does a larger portion of work during the throw.  You are pivoting and blocking with that leg.  The other leg does not have to take weight or explode as hard as that leg.

That is my theory.  I am sure there are others on this board who can give better explanations.  Maybe Coach Mac

My left leg is also stronger than my right. Truly odd. I also put the left leg forward when I do jerks and I jump off it. Even though I could not kick a ball with my left leg to save my life. Bizarre.

Typing in the dark at 05:30 just prior to putting in the
"mother of all cement throwing pad "...(60 x 55 '
)....first of all I would look at the subject and have you
do a over-head snatch grip squat to see if there are
any AB-normal "im-balances"...this is diagnostic
FUNCTIONAL test...do the heels come up (lack of
flexibility) OR does one leg turn in...this can be a
couple of things: one leg excessively longer than the
other...knees counter inwards or outwards...low
back excessive SWAY....Oly bar falls forwards or
backwards ect.

This will give you a clue to whats missing or needs
work. Dave Brown is contemplating a "make-over"
for next year and this is what we will start with.

Some intresting studies done on crossover
strength...I don't have the numbers in front of me but
injured legs will get stronger exercising the mobile
limb...this is the nervous system at work.

Since BALANCE is the key to good performances try
throwing the implements back with the non-
dominant side...try to do mundane tasks (opening
doors ect. ) with the non-dominant arm ect.

Most good ART or Sport Chiro's can find im-
balnces...good luck on the balance issues
especially on Jan 1rst....
