The Secret Behind His Serve
Sampras's serve followed a more classic approach. He utilized a more circular windup, taking the time to deliver himself the powerful bomb at contact. Throughout his motion, Sampras is completely relaxed. There
is little to no tension as can be seen by the fluidity of his serve. His serve contains no hitches, no pauses and no extra motion often seen in lower level servers.
Notice how the motion appears "slow" and relaxed, and sampras takes
time before starting his motion.
Sampras generated phenomenal racket head speed at contact. His serves included enourmous power and spin. One of the reasons for this is because
he coiled his body like a spring before unleashing all the stored potential energy right at the moment of contact.

Notice the torso angle and hip position of Pete. His upperbody is fully loaded, and his hips are turned towards the backfence, it's as if he is nearly showing
his torso to the backfence.
Pete's lower body is fully coiled as well. Notice the deep bend in the knee in his stance. But all of this loading is done so he can get maximum loading or "coil" so when it comes time to swing he will have
massive amounts of different torques working in his favor to generate his trademark serve.
Notice also how Pete's shoulders and tossing arm is completely sideways. He does not prematurely drop his tossing arm until he is ready to launch upwards. Many lower level players make
the mistake of not keeping their shoulders and left arm in the "loaded" position, which in turns robs some of the potential power on this motion.
