Amanda Bynes doesn't just work out. The girl twerks out.
At least according to a fellow gym-goer, who sketchily took a brief video of the former Nickelodeon star's workout regimen Friday.
Whatever she's doing on that machine, it's ... unique.
While it's not as provocative as the Twerking video that got 33 San Diego high schoolers suspended, there is some quality use of her lower extremities.
Her running style, too, pretty much speaks for itself.
Earlier this week, Amanda Bynes Tweeted "I weigh 135! I've gained weight! I need to be 100 lbs!" We don't agree ... but she'll drop the pounds if she keeps this up.
