Female looking to get into construction...?

Guys, how do I get into the construction field? I'm sick of sitting in an office chair all day at a computer getting fat. I want to do manual labor and construction seems like the most fun. I like painting and am really interested in flooring, like tile laying, carpet, laminate. But how do I get experince so they don't laugh at me when they realize I'm a young attractive female that wants to work with construction workers?
