This can be tricky problem to solve without actually seeing your
forehand however I have the following suggestions:
I`m also a lefty and use a semi-western grip and have gone
through exactly what you are right now so I completely understand!
You said how you used to have sharp, accurate forehands...what
happens is we become consciously aware that the forehand performs
well and so expect it be there on demand...
we know we have the hand skills to be produce effective forehands
but our footwork can go down hill!
We think we`re doing enough but we can get lazy and rely on the
hands skill to get us out of hot water without actually realising
we`re doing this! Incredibly frustrating!!
We become consistenly inconsistent!
What we need is those little adjusting steps which will really make
While you could look at stance, timing, etc. these are secondary
issues....the primary issue will be you requiring effective footwork.
You could say timing is out....but the reason your timing is out is
because you haven`t rotated the shoulders at the right time...which
is because you didn`t reach the ball or adjust your body to the ball
effectively.....see what I mean by primary and secondary problems
This solved my spell of trouble and recommend it this approach for you!
In addition...for anyone to make a change you have to exaggerate
it! So get on court.....really work hard on and exaggerate the footwork
and also hitting topspin with lots of net clearance.
You`ll be well on your road to bringing back what you know you have!
