Multiplex is juggling jargon for a throw in which more than one object is released. A three club start is an example of a multiplex with three objects, however in this section I will concentrate on 2 club multiplexes, since they are more relevant to 3 club juggling.
In order to throw 2 clubs at the same time from the same hand, the correct grip must be used to ensure that they don't collide with each other when thrown. Most people find that the best way to do this is to hold them with the outside-most club pointing down:
Try a few experimental throws from both hands, the clubs should fly up together, and split apart cleanly, both spinning at the same rate. If you find that the clubs knock together in the air, then try tilting your hand to the left or right, so that the club handles are parallel when viewed from above, rather than one sitting on top of the other:
To make one club go higher than the other one, hold it further down the handle. The nearer to the knob you hold it, the higher it will go:
Multiplexes can be thrown with the clubs pointing forward, as normal, or you can use Outside Flats. Reverse Spins and Inside Flats can also be used, but they require the opposite grip, i.e. the inside club will point downwards, rather than the outside one.
