 Your body must remain rigid in a generally straight line and move as a unit while performing each repetition.At the end of each repetition, the scorer will state the number of repetitions you have completed correctly.If you fail to keep your body generally straight, to lower your whole body until your upper arms are at least parallel to the ground, or to extend your arms completely, that repetition will not count, and the scorer will repeat the number of the last correctly performed repetition.
