13 stringent rules many NFL cheerleaders have to live by

• Some teams require cheerleaders to maintain a strict body weight, cover up tattoos and body piercings, and forego wearing sweatpants in public.

• One New Orleans Saints cheerleader was even sacked over an Instagram post, The New York Times reported, prompting a discrimination case.

NFL cheerleaders must adhere to a number of intense rules if they want to keep their jobs, according to a recent report from The New York Times.

These directives don't just pertain to cheerleaders' workplace conduct, either. The mandates dictate how cheerleaders can behave when they're off the clock, too.

Specific guidelines vary from team to team, but it's not the first time the treatment of NFL cheerleaders has been the subject of a controversy.

Some cheerleaders reportedly earned less than $1,000 a year in 2016, according to USA Today, and Time reports multiple lawsuits have been filed that allege that teams paid below the minimum wage. And now some are arguing are that the rules are sexist and that the NFL cheerleaders in general are exploited. A former New Orleans Saints cheerleader, who was fired after she posted a photo of herself in a one-piece outfit on Instagram, has even filed a discrimination case against the team, The New York Times reported.

Here's a look at some of the rules many NFL cheerleaders must abide by:
