Se sufre pero se goza (1986)

A man who married a very rich woman wishes to help his brother-in-law who is having financial problems, so he starts a business as a women's wrestling promoter--a business that involves suffering but also has its enjoyable side. His side business begins to go well too: selling oxygen pumps to older male spectators who can't stand too much excitement without help from a breathing apparatus. To enhance the popularity of the matches, the masked vs bikini wrestler matches are announced as no time limit, best 2 of 3 falls, the loser to drop either her mask or her bikini in the center ring. With so much at stake, the crowds grow at the ticket office.
