Absolute Beginner Series
If you're looking for some more follow-along videos, for at-home ballet barre classes, Ballet Misfit has an "Absolute Beginner" series of 5 videos on YouTube, that are nicely done and quite manageable.
She has two versions of each video in the series: one with the combinations explained first, and another with the explanations removed (labeled "combinations only".)
A WORD OF CAUTION: As always, listen to your body and only do what is within your ability. Skip or modify anything that causes you pain or discomfort.
