My arms start down by my side. When I deem ball at disposal, I start counting "one thousand...". When I start count in my head my arm comes up to my chest. It goes out as I say "one." It comes in to my body as I say"one thousand"....and back out when I say "2." And so on. The visual indicator at the start is my arm going up to my chest.
