Personal trainers are there to motivate clients by setting goals and providing feedback and accountability to clients. They also measure their client's strengths and weaknesses with fitness assessments and to measure their client's improvements. They will also pay close attention in many other aspects of wellness besides exercise, including general health and nutrition guidelines.

Personal training will assist with exercise behaviour patterns, improve perceptual benefit-to-concern ratio for exercise (decisional balance), and increase confidence to choose exercise in the face of other time demands. Personal training results in higher strength, higher workout intensities, and higher exertion during exercise
