This study was to clarify strength factors using 12 selected exercises on the Universal Gym, and to determine what measures present a valid method of assessing strength of college-aged males, Eighty-eight males enrolled in beginning weight-training classes used the Universal Gym for twelve weeks, Subjects were tested for maximum strength on 12 exercises, Alpha and canonical factor analyses were performed on raw scores of all measures, and on scores when body weight and standing height variances were removed. A three-factor structure of upper extremity, lower extremity, and trunk strength was revealed when weight, and weight and height combined were statistically controlled. Results showed that residualized scores of weight can be used to evaluate strength on the Universal.Gym,
