The yoga practice isn’t a contest with our body, it’s a dialog with our body. We can adopt a confrontational style of discourse, or we can adopt an intimate, loving one.
If repetition is the thing that takes us further into the practice, the attitude we take into our repetition is going to constrain how the practice serves us.
The nature of practice is that it shows its effects over time. We must take the time to let it mold us.
