The scope of practice for a personal trainer is to enhance the components of fitness for the general, healthy population.
Proper exercise prescription may result in improved body composition, physical performance, heart condition and health outcomes.The decision to hire a trainer may be related to a perceived ability to facilitate these factors through proper prescription and instruction or factors related to motivation and adherence. A trainer pays close attention to their client’s exercise form, workout routine, and nutrition plan.
Few studies have investigated training for men, however, training in women has been shown to exercise behavior patterns, improve perceptual benefit-to-concern ratio for exercise (decisional balance), and increase confidence to choose exercise in the face of other time demands (scheduling self-efficacy).
Personal training results in higher strength, higher workout intensities, and higher perceived exertion during exercise in women. Although women working with personal trainers do self-select heavier loads than women who did not, the loads used are still below recommended training load percentages.
