Movement. The first step in establishing a
strong foundation with the body is by facing the
undeniable truth about this game. A tennis
player faces an angle of possibilities, which
means the ball angles, or moves, away from you
either to your right or to your left (1A). The
ball is not hit at you. (The court is drawn to
scale.)
The ball is moving away from you, and while
there are different directions to intercept it, you
want to hit the ball with some power and send
it back where it came from, you simply don't
want to run over and touch it or just stop it.
You've heard often enough that moving into the ball gives you power, that is getting your body's
momentum behind the stroke and into the ball equals power. Why doesn't that happen often
enough for you? Because if you either move parallel to the baseline, turn sideways, or pivot one
foot to the side, you're moving away from the ball and not into it. It's simple geometry.
To see this, imagine you're ready to throw a tennis ball at a friend's car going past you parallel to
the sidewalk on which you're standing (1B). If you throw the ball before the car is at a right angle
to your position, you're throwing the ball INTO the car and it hits with force. If you throw after
the car passes the right angle mark, the ball's moving AWAY with the car and catches up with it
later, hitting with less impact.
INTO THE BALL
Let's apply this to tennis. You're in the ready position behind the baseline
and a ball is hit to your left side (1C). Draw a line from your position to
form a right angle to the ball's flight line. If your movement pattern takes
you to the inside of that right angle mark, that is in the direction of the
net, you're moving forward and INTO the ball. And your ever so
important momentum is going into the ball, which means power.
Diagram 1C shows that by moving parallel to the baseline you're moving away with the ball,
catching up to it later. As a result your momentum is going off toward the side fence and not into
the ball, it takes more time to reach it, and there's little chance your body can structure itself to
support your contact spot because the ball has passed you by.
I know you feel you don't have enough time in which to hit the ball, but you can't give yourself
more time to hit it by taking more time to reach it because the ball is angling away from you and
getting lower.
DIRECTIONS
In what direction lies forward? To one side? Into the ball? Diagram 1D explains. You want to
move into the ball, you want your momentum into the ball.
The angle of your movement relative to the ball's flight line helps you reach the ball on time, Step
2, structure the body for a strong hit, Step 3, and helps you develop power in a simple manner and
not in one you're used to that is counterproductive to success, Step 4.
With your ready position three to five feet behind the baseline, moving into the ball means just
that, moving forward. Not at full speed, simply not away from the ball, not parallel to the baseline
or backwards. But this idea of moving forward won't happen if you first pivot one foot against the
ground, turn sideways, or step backwards as diagram 1E shows because, undeniably, the ball's
moving away from you. Less is more.
It's clear you need to move forward, into the ball, and not waste time or opportunity by pivoting
against the ground or turning sideways. How should the feet move to achieve this? Which one
first? Step 2 explains.
