Must add written and or verbal instructions !
One of the reasons you see a PT is to perform the correct technique in order not to injure yourself. Not to mention sometimes forgetting the correct steps. It is not reasonable to have your trainer always accessible. Especially when performing these exercises at home. You should not have to look it up on YouTube. Written instructions are a must, Verbal as well for those of us viewing them on a small phone screen while trying to perform the exercise. thank you
