American Council on Exercise has a good certification for Older adults & special populations!
Out of curiosity, why do you feel the need to obtain a certification to work with seniors?
If you were able to develop “a yoga based class for seniors” prior to any certification, do you not feel knowledgeable enough to now instruct it?
It would be great to hear your thoughts if you’ve got the time. Thanks in advance and I hope to hear back from you!
