Do you teach contraindicated exercises in your group exercise classes or personal training sessions?
Standing quadricep stretch is contraindicated?
I think until we get fully regulated, licensed, and mandated to follow only certain exercises, it really is up to our profession to always consider the source, pay attention to the people or person you are training and know limitations.
We are not about “one size fits all”, we have to be flexible with our thinking, and sensible with our actions.
