In a conversation with the Belga News Agency, the gymnast remarked:"I’ve reached what I wanted and was able to reach. I’ve been able to prove what I had in me.

Is it worth putting my body on the line?’ My conclusion: it’s been enough. It has been beautiful."Nina Derwael had represented Belgium at the Paris Olympics last year.
