LIMITATIONS
EMG is a complicated biological signal that indicates the activity level of the muscle. There are however, many factors that can affect the relationship between the activity level of the muscle and the recorded EMG, such as fatigue of the muscle being tested and the electrode-skin interface. Though these have been carefully monitored, it is possible that interference of some sort could have interrupted the results.

The methodology did not consider certain extraneous variables. In the bench press, these variables included elbow and shoulder angles, and angle of back extension. In cable crossovers, it did not consider wrist, elbow and shoulder angles, level of trunk flexion, and the path taken by my hand in the movement. As these variables were not controlled, the potential for inconsistent motions in each movement could ultimately affect the internal validity of the study.

Another possible confounding variable arises in the review of literature. There is no research comparing the differences of cable crossovers between women and men, and very little if any quantifying a comparison of cable crosses in relation to any other motion. Because of this, there is little background knowledge on the effects of gender, timing, body angles, range of motion, the path of the movement, and experience as it impacts neuromuscular attributes.

Another limitation deals with the participants... Me. One previously-trained, college-aged, male participant does not adequately represent any particular population and only gives some indication of accuracy in the readings.
