do boxing / go boxing

[englishhobby]

Can a boxer say "I do boxing professionally"
Can anyone say "I go boxing" (= do it as a sport) if he attends boxing training classes?

I am not a teacher.

A boxer would say, "I box professionally". Only if he's taken a few too many to the head might he say "I do boxing professionally"

It would be fine for a regular activity to say something like, "I go boxing on Tuesdays"

(Not a Teacher)

I feel that a native speaker won't necessarily cock an eyebrow if you say, "I do boxing professionally."

For instance:
"I do carpentry for a living."
"He does a little boxing on the side."
"I do sparring whenever I get the chance."
"She does weight lifting in international competitions."

I'm not saying it's always preferable over using the verb, but "do + participle" isn't an unnatural construction either.
