Farrah Abraham's getting ready to fight Nicole "Hoopz" Alexander, but first she's gonna hit you ... with a damn-near naked training session!

The ex-'Teen Mom' star is partnering with porn camming site CamSoda to webcast her Wednesday night training for the celebrity boxing match. The hook, as ya probably guessed, ain't watching Farrah work a speed bag ... it's watching her do it in skimpy workout gear.

Sources at CamSoda tell us Farrah will slip into 4 outfits during the workout, and whoever tips her the most during the camshow ... will win one of the sweat-drenched items. For example, we're told she'll be wearing this little number, as well as a see-through version.

As we reported, Farrah agreed to fight Hoopz for a celebrity boxing match going down on November 10 in Atlantic City. Drita D'Avanzo wanted to fight Farrah, but Farrah turned her down.
