Bodyboard for everybody
Bodyboarding actually originates from an ancient form of riding the waves / surfing on one's belly, without any form of equipment. The bodyboard itself differs from a regular stand-up surfboard since that they have no ventral fins.
There are a few different ways of riding a bodyboard. Prone, dropknee, and stand-up. The most popular is prone, that allows you to do a lot of tricks that are not possible to do if you are surfing a regular stand-up surfboard. Sine a bodyboard doesn't have any fins to help you stable it's an art in itself to keed a bodyboard moving in the right direction. On the other hand, the lack of fins opens up for a new range of tricks, such as the 360 spins.
When choosing the right board you should measure the distance from the floor to your navel. The nose of the bodyboard should reach somewhere between the top of your hip and your navel. If you are a heavy rider or surfs smaller waves it is important to consider finding a board, that will keep you floating. Don't make the common mistake of buying a longer board to get more floatation. Instead, you should choose a wider body board with a slightly wider tail and/or a thicker core too.
A Bodyboard should always be flat
You should make sure that your board is flat. Hold the board on its edge and look down its rail where it should be nice and flat. Boards with a lot of rocker are hard to catch waves on, since they push the water and are slower. You will need rocker for turns, but then you should be able to bend it into the board whilst riding. This maneuver is easy to learn - difficult to master.
