Fred,

Yes. I had a problem. What
I did was to start by keeping
the toe of the raised leg on
the floor for the first few days.

Then, I raised the leg about
one or two inches after the
first round. Gradually, over
about two weeks I was able to
raise it higher.

I still have moments when I
cannot raise my leg all the
way without losing my balance.
But that is seldom now.

If you notice the tape of
Master Lin, he doesn't raise his
leg as high in the beginning
of the first round as he does
later.
