A number of strengths can be named for the current study. Since the majority of research in this field uses school or college samples, the recruitment of a sufficiently large sample of weight-training men can be considered to be more meaningful for those persons at high risk for body image problems. Also, the investigation of biological, psychological and sociocultural factors simultaneously, using a biopsychosocial framework, allowing assumptions on different degrees of importance for drive for muscularity, can be useful. Further, investigating biological factors, such as the FFMI and age separately, provides important directions for future research. Especially, the effect of age, along with hormonal influences should be investigated on a longitudinal level, since changes in its relation to drive for muscularity can be assumed as being non-linear.
