My flossing analogy may have been a bit off. Lifting weights might be a bit closer. The difference is that you don’t really feel like you get better at flossing over time, or have different experiences of the flossing process. With lifting, one of the things that you metalearn is how to feel your body working and how to do to the exercise in a way that makes it work better. You learn to find and trace an “edge” of performance (and enjoy it). That’s an interesting process in itself, and it also is an important element in you making progress in your lifting and strength/fitness development.
