Incomplete question.
Answered based on the full poem as found on the Georgia Online Formative Assessment Resource (GOFAR).
Answer:
she later came to develop an interest in her kickboxing class
Step-by-step explanation:
For example, we notice in the earlier stanzas, Ballerina has a complacent attitude about her kickboxing class. This was evident when she said,
"My kickboxing class has as much grace as
A herd of stomping elephants.
Stampeding towards a watering hole.
It’s a far cry from warming up on the bar, "
However, a change in her attitude begins to occur in the last six stanzas of the poem. She begins to cooperate with her instructor, made evident when she said, "...But I force myself to bounce on the balls of my feet like he told me. " Furthermore, she finally came to appreciate the kickboxing class that she said,
"...when we finish and step back, the class breaks into applause.
I curtsy, laughing, and shake hands with my teacher,
Who has taught me so much more than I expected."
