The Certificate III in Fitness reflects the role of instructors who perform a range of activities and functions within the fitness industry. Depending on the specialisation chosen, this qualification provides a pathway to work as an instructor providing exercise instruction for group, aqua or gym programs.

They work independently with some level of autonomy in a controlled environment such as fitness, leisure, aquatic and community centres where risks are managed through pre-existing risk assessment and hazard control processes.

Individuals who specialise in Aqua Exercise Instruction deliver water-based exercise sessions designed for participation by a group of clients. Sessions may be freestyle, pre-choreographed or circuit style. They also have the skills to rescue a client in distress, and an appropriate level of pool deck fitness and endurance.

Individuals who specialise in Group Exercise Instruction deliver exercise sessions designed for participation by a group of clients with a mix of ages/fitness levels. Sessions may be freestyle, pre-choreographed or circuit style. These individuals instruct and demonstrate complete exercise sessions to groups with limited individual interaction.

Individuals who specialise in Gym Instruction provide individually tailored client assessments, provide technique correction as needed, and develop and demonstrate programs. They also provide supervision of a facility or service, keep equipment clean, tidy and well maintained, and handle various customer inquiries.
