Everybody has a different level in every class, and your role is to make sure that everybody feels welcome.
If the person doesn’t have much experience, start with lower body movements, then add upper body movements. This way, it might be less confusing for them.

Remember to offer advice on the techniques that your student is learning or to offer modifications if they are not able to follow all the steps that you’re showing at this moment.
