People often assume that the fastest route to 20 is to do 20 every time. That’s a misunderstanding of how skill learning works. Repetition matters, but only repetition you can perform with the correct mechanics.
Another misconception: that speed equals progress. In reality, speed often arrives after control. If your rotation speed forces your body into awkward positions, it doesn’t build the foundation you need.
Finally, some treat “20 times” like a single event. The truth is that progress comes from sessions where your technique stays consistent enough to improve your movement map, not from one exhausting attempt.
