In poker, they call it a “tell,” a movement that shows your intention. Some people almost warm up into a move instead of straight on application of a technique. In football, linemen know what the other side will do based upon their feet. The flipside of this is you can fake or disguise your intentions. With takedowns, you can use level changes to disguise when you are going to shoot for a takedown. Doing a move over and over is also a problem. It is easy to defend. Change it up. Arm bar, then to a choke, then back to an arm bar. Not arm bar, arm bar, arm bar repeatedly. Break the rhythm up.
