I think your mistake is that you don't know what bowling looks like to begin with. Skip to the regular guy at https://www.youtube.com/watch?v=EfEKI5iL-Ok&t=50s

I think your mistake is that you don't know what bowling looks like to begin with. Skip to the regular guy at https://www.youtube.com/watch?v=EfEKI5iL-Ok&t=50s https://www.youtube.com/watch?v=EfEKI5iL-Ok&t=50s - he looks like he's melodramatically performing in _Swan Lake_ with his spare arm swinging way out. (Which is less dramatic than many bowlers.) Then go back to https://www.youtube.com/watch?v=EfEKI5iL-Ok&t=25s https://www.youtube.com/watch?v=EfEKI5iL-Ok&t=25s and see how he's just sort of hunched over and casual.
