Tips of a Good Serve -
1) Use Continetal grip(commonly known as hammer grip). To ensure you really master this grip, leave a space between your index finger and middle fingers. Imagine you are reaching forward with your index finger to pull a trigger. By positiong your fingers, you will find you have more support on using this grip. This grip is also used for volley, slice, dropshot.
For Good Serve, keep your tossing arm straight, bring your hitting elbow up and roate your front shoulder away from the Net.
2) With the Serve slightly in front and over your hitting shoulder, make contact at full extension( commonly, known as High-Five, use in teaching kids). Remember to bend your knees before you contact the ball.
Tennis Biomechanics of the serve
There are 2 types of foot work in Serve. Foot-up(pinpoint stance - 2 legs together) and foot-back(platform- One foot front and one foot back) techniques.
Foot-up- During the tosss and recquet preparation phase, the foot-up technique moves the rear foot up next to the front foot. Foot-back technique keeps the rear foot back from the forward during the tosss and racquet preprations.
The Difference between these two technique is that foot-up techniqure favors generation of vertical ground reaction forces that are ffective in creating racquet spped and ball topspin.
The wider stance of thefoot-back techquie creates greater horizontal gorund reaction forces that might help serve & vollye players be quicker into the court folloing the server.
