Create enjoyable fitness experiences by incorporating music, cueing techniques and progressive exercises that keep participants engaged and coming back.
Build connections with your community by getting to know participants, answering questions and providing friendly, professional customer service.
Support a safe and positive facility experience by preparing equipment, following safety procedures and responding confidently in emergency situations when required.

Continue growing your skills by staying current with aquatic fitness trends, techniques and best practices.
