Underhand Serve
A skill for the beginners, however it can be very effective when served correctly.
1. Stand with left leg in front (for right hand servers)
2. Toss the ball slightly in front of the right shoulder
3. Swing your right arm as your body turns to the left, hold right fist
4. Make contact with the ball with your fist, and with your right arm straight
5. Make sure the contact point is behind the ball in the lower portion, not under the ball
6. Make sure your arm is straight
