A physically impaired person can be a good yoga instructor: they'll suggest alternatives, different/better cues, or provide more accessible classes such as yin or seated yoga. Just because they are physically impaired now doesn't mean they were before, and an instructor won't necessarily move through the poses with the class since they can have 2-3 classes per day.
