Great question! I’d recommend starting with Learning Paths. It’s our guide that helps you answer 2 big questions:
1) Where do I start?
2) What do I work on?
The second video on that page gives a run down on how to navigate the site. One of the features covered is the search bar. You can use that to find lessons that cover different topics.
With that said, the most common beginner topics are covered in our Beginner’s Course. Such as the 2 lessons you mentioned about proper holding technique.
I’m always around if you have questions too. Please don’t hesitate to ask 🙂
