Arms

Remember to use your arms mainly to motor yourself around the course and to keep your balance while running. Extend your arm only when you need to "push" your dog out or away. If you run with your arm(s) constantly extended it will be less clear when you need your dog to respond to a hand signal. You wouldn't run a course muttering, "jump... jump... jump... JUMP!... jump... jump, etc." -- shouting "jump" louder only when you encountered an actual jump. Be just as clear with your arm and hand signals as you would be with your verbal signals.
