What do you get

Note that you will get immediate access to the 2019 videos of this class. I didn't run a class in 2020  due to all the distractions and had not recovered back to 100% from being ill in 2021. The late 2019 version is the best version of this class!

I am updating and re-recording the entire class right now and will launch soon. If you sign up now, you will get access both to the old and new version!
