If more frequent but shorter lessons are better, then why don’t you teach 7 days/week?

Everyone needs a little break from learning to process the information and in this case to give muscles a chance to recover. In addition, you need to be able to spend time with your family, as does your Instructor. Weekends are family time. Periodically, if weather or other issues have caused lessons to be cancelled for numerous days, your Instructor may choose to offer make up lessons on a weekend. This is strictly up to the Instructor and based on the availability of parents.
