As a musician, I find these practice videos invaluable.
Just as it is easy to play along with a tutor, dancing along with the tutor is also much easier than practicing alone.
I have a weekly lesson with my daughter on Zoom but realized quite soon that 30 minutes a week is simply not enough.
I am also aware that I spend a lot of time seating on my rump!
The good thing about YouTube videos is that you can slow them down as you learn.
Of course, nothing replaces a real teacher-student relationship but the videos keep you in trim and mean you can dance every day.
