What is the sentence of calisthenics?

Calisthenics is not a crime, so it doesn't have a sentence. It's a form of exercise!

Perhaps you meant to ask something else? For example:

* What are the benefits of calisthenics?

* What are some examples of calisthenics exercises?

* How can I incorporate calisthenics into my workout routine?

Please clarify your question so I can help you better!
