toss starts the serve, but it can be a problem.
Here are some suggestions for acquiring a consistent
your service stance. Draw a circle on the ground
where you would want the ball to land. Toss up
a ball, while at the same time bringing the racket
to the backscratch position, and let the ball
hit the ground. Mark the spot with the ball. Now
toss 4 more balls to see your range of accuracy
in relation to the circle. As your consistency
improves, reduce the size of the circle. A caveat:
this exercise is very effective providing you
keep your chin up until the ball has bounced.
the left hand swings out to the side, the toss
will be very erratic and the body will not be
aligned for the proper shoulder rotation. Just
by crossing the arms and bringing the ball to
the right of the body, the serve will be corrected.
