During a standard pendulum serve, move your middle, ring, and pinkie fingers, adjusting your grip on the bat handle until they support the rubber. This will give you more control.
By shifting your left foot to be adjacent to the table's left corner, you'll be positioned to view the ball parallel to the table's end line, ensuring better vision. Place your right foot a few inches behind your left, pointing away from the table. As you lean forward, shifting your weight onto your left leg, and with the ball outstretched in your left hand, position your right shoulder behind your left. This ensures you face away from the table, better anticipating your serve.
Throw the ball upwards, move your right shoulder forward, and allow your left shoulder to fall back. Brush across the left side of the ball to produce a sidespin.
