In the serve fundamentals section of FuzzyYellowBalls, we suggested you
use the party stance when you were first learning the serve because it’s
a very simple stance and lets you execute all of the fundamentals of the
serve. Not only is it simple, but it is also effective. Many pros,
including Roger Federer, use the party stance. To quickly review, the
party stance is where your feet are about shoulder width apart, and your
front foot is angled into the court at about a 45 degree angle. Your
back foot is located about a foot behind your front foot and is angled
parallel with the baseline.
The party stance is part of a larger group of stances called platform
stances.” A platform stance is where you have your feet about shoulder
width apart, and the angles of your feet are variable. During the
service motion, your feet stay the same width apart. They do not “move”
until you jump up off the ground.
A second type of stance is called the pinpoint stance. Pinpoint stances
are where your feet are only a few inches apart or are basically almost
touching. The pinpoint stance has been popularized lately by guys like
Andy Roddick and Gael Monfils. There are some variations to the pinpoint
stance. The main pinpoint variation, called a hybrid pinpoint, involves
starting in a platform stance with your feet wider apart, and then on
the way to your trophy pose during your motion your back foot comes up
next to your front foot into a pinpoint stance.
There are several advantages and disadvantages that coaches typically
associate with these various stances. With the party stance, which again
is a platform stance, the weight transfer forward during your motion is
supposed to be pretty easy. The wider your feet are apart, the easier it
is to get all of your weight onto your back foot, and then move it all
to your front foot as you hit your racket drop position. With a pinpoint
stance, where your feet are closer together, now it’s easier to explode
up and into the tennis ball. You’ll get a little bit higher, and thus
you’ll get a little bit more power because your feet are closer together
and that makes it easier to use both legs to push off at the same time.
With the hybrid pinpoint stance, again where you start in a party stance
but achieve the trophy pose in a pinpoint stance, some coaches think you
can get the best of both worlds. The difficulty with this stance is that
there are more moving parts, it is harder to time, and it is more
difficult to control your toss and balance throughout the motion. With
all this said, in my opinion the so-called advantages and disadvantages
of these stances are more in a coach’s mind than they are actually in
reality. I’ve never seen any study done which proved that one stance was
better than another, and the most important thing is that you choose a
stance that you are comfortable with and that lets you execute all of
the fundamental mechanics correctly.
The final point we want to make about stances is that you will need to
tweak your stance slightly depending on whether you are serving to the
ad court or to the deuce court. You will still use the same stance, but
the angle at which you position your entire body will need to change. If
you are in the party stance and serving to the deuce court, your feet
will be angled a certain way. If you then take that exact same body
position and angle and try to serve to the ad court, your ball will
likely go wildly out. You need to alter your body position slightly so
that you are facing the proper direction to serve to each side of the
court. Lets take a look at some pros’ stances starting at 3:50 in the
video above. First up is Tim Henman, and just like we had said in the
fundamentals section, Tim uses the party stance. He’s got his feet maybe
shoulder width apart or slightly wider, and one of the reasons he might
use this stance is because Henman serves-and-volleys frequently. Because
this stance makes transferring his weight into the court (and not up)
easier, it allows him to get his weight moving towards the net before he
even strikes the tennis ball. We can compare Henman’s serve stance with
Andy Roddick’s (at 4:17), and we can see that Roddick is using a
pinpoint stance. His feet are only a few inches apart. Roddick obviously
has a hugely powerful serve, and he really gets up into the air behind
his serve. The pinpoint stance is helping him get higher off the ground
and generate that extra power because he can jump up off of both legs
instead of just one (or one-and-a-half [back toe]). Let’s finally look
at John Isner’s serve, which is also a monster. John uses that hybrid
pinpoint stance where he starts in a party stance but gets to a pinpoint
stance in his trophy pose. In the first picture of John at 3:35, he’s in
his party stance, but at 4:41 when he gets to his trophy pose he’s now
clearly in a pinpoint stance with his feet practically touching. This
allows John Isner to transfer his weight forward but at the same time
jump very high off the ground and use that height to bomb his serve down
at his opponents. Let’s finally go back to Tim Henman and split screen
his stance on the deuce court and the ad court at 5:00 in the video
above. If we draw a line through his back foot, we can see that it is
basically parallel to the baseline when he serves to deuce and it is
angled further back when he is serving to the ad court. So what he has
done is to change his body position so that he can serve effectively in
a different direction.
