给定一篇短文，试修改其中的语法错误。
“After eating lunch, the gym was the perfect place for some exercise.”
"After eating lunch, the gym was the perfect place for some exercise." should be corrected to:

"After eating lunch, going to the gym was the perfect way to get some exercise." 

Explanation: 

The original sentence has a subject-verb agreement error. "The gym" cannot be the subject of the sentence because it does not make sense for the gym to do something. Instead, the subject should be the person who is doing something, which is implied in the original sentence but not stated explicitly. The corrected sentence adds the subject "going to the gym" and changes the verb to "get" to match the subject.
