You will take 4 Beginner Series classes (those are on assigned days/times).
You have 3 more classes to take, these will be based on your needs and schedule.
Try to take one class between each Beginner Series class. Also, try to vary the teacher/type of class that you are taking.
For example, if you have a Beginner Series class each Tuesday, take a Stretch and Chill class Thursday night. Then the next week, take a Yoga Fundamentals 1 class on Saturday morning. Then, after your 3rd Beginner Series class on Tuesday night, take a Stability and Flexibility class on Monday.
Try out different classes/styles/teachers to see which ones are the best fit for you (because each teacher and style is different!).
