at least here in my area (Raleigh, NC), it would be a matter of finding a club that partners up with the Arthritis Foundation to offer aquatic classes. It usually requires a pool that has a higher than normal temperature (about 89 + degrees F), and those facilities are not that easy to find. You would need to become an instructor at that facility. I would check out YMCAs first as they tend to work with the Arthritis Foundation.
I teach water aerobics, and some instructors teach what we call “Range of Motion” classes which are geared towards people with arthritis. At least at my facility, it is required that you hold an aquatic group exercise certification. I looked at your profile and was not sure whether your certification was for water of land.
AEA is in my mind the “gold standard” if you can get to them. AFAA also has an aquatic program that is a good overview of the basics.
Some gyms have pre-designed programs you can use if you shadow or follow along with an instructor, or go through an in-house training.
If you know a gym you plan to work for, I’d recommend you ask them what they are looking for; an older group vs. an athletic group would also change where you’d want to start.
Best of luck!
Agree with Ashley. When I taught water I took the AEA and was very happy with the training.
I do not offer a certification class. But I do offer CECs in aquatic exercise for certified Group Fitness Instructors and Personal Trainers.
Interested instructors can check out my website at www.hawaiifitnessacademy.com . The CEC courses are under the “Fit Pro Cafe” tab, Beyond Basic H2O and HIH2O. I have been instructing elite athletes to post rehab clients in the water for over 30 years. If you are ready for a vacation, why not take a CEV. A Continuing Education Vacation to the Big Island of Hawaii.
I am a certified Group Fitness Instructor and Personal Trainer (with two college degrees and dozens of specialty certs). My courses have not been rejected by any NCCA organization to date.
