I was looking through very old japanese travel blogs and reading comment sections for practice. I ran into this phrase that I can't look up anywhere.
Here's the full page if context helps. http://boniting.com/nappi/2009/10/dallas-world-aquarium.html.
This is the sentence that got me thinking.
Google translate say it means "I have a physical fitness". I'm sure that's wrong, though, given how google is. "
"張る" seems to have so many meanings. So I'm not sure what it means if its attached to "体". Also, what's the function of かい here? Is it related to the counter 回?
