An exercise physiologist performs pre-participation health screenings, conducts physical fitness assessments, interprets results, develops exercise prescriptions, and applies behavioral and motivational strategies to apparently healthy individuals and individuals with medically controlled diseases and health conditions to support clients in adopting and maintaining healthy lifestyle behaviors. An exercise physiologist is typically employed or self-employed in commercial, community, studio, corporate, university, and hospital settings.

Clinical Exercise Physiologist:

A certified healthcare professional who utilizes scientific rationale to design, implement and supervise exercise programming for those with chronic diseases, conditions and other physical conditions where exercise training has been shown to be of therapeutic benefit. Services provided by a clinical exercise physiologist include, but are not limited to, individuals with cardiovascular disease, pulmonary disease, and metabolic disorders.

Personal Fitness Trainer:

An exercise professional with specific qualifications who develops and implements an individualized approach to exercise using premeditated, non-choreographed exercise programs, including technical coaching and instruction in physical fitness and conditioning for an individual client, or organized groups of clients, who require pre-participation evaluation or instruction prior to engaging in the exercise regimen. Personal fitness trainers may work with any individual who does not require medical clearance prior to engaging in exercise or who has been cleared for exercise by a medical physician with a recommendation to participate in physical activity without the need for medical supervision. 'Personal fitness trainers' include personal trainers, professional fitness trainers, fitness coaches and persons performing similar physical fitness training instruction regardless of the designation used. This definition does not include group exercise instructors, physical activity leaders, certified athletic trainers or Pilates teachers.

Pilates Teacher:

An exercise professional with specific qualifications who develops and implements individualized and/or group exercise programs using premeditated, choreographed and non-choreographed exercise programs, including technical coaching and instruction in physical fitness and conditioning, for an individual client, or organized groups of clients, who require pre-participation evaluation or instruction prior to engaging in the exercise regimen. Pilates teachers may work with any individual who does not require medical clearance prior to engaging in exercise or who has been cleared for exercise by a medical physician with a recommendation to participate in physical activity without the need for medical supervision.
