The former Nickelodeon actress has been seen making frequent trips to gym as of late. She was spotted getting her sweat on (while wearing the same ensemble) two days in a row last week, although both gym sessions were interrupted by a short trip to a nearby gas station, where she is said to have purchased cigarette rolling papers. She also hit the gym again on Friday, but opted to don cropped black leggings and a retro video game sweatshirt.

Amanda appears to be amping up her workouts since returning home from treatment, and she recently splurged on a $3,250 week-long fitness retreat in Utah.

"She was interested in getting healthier…to get in better shape, to lose about five pounds, but mainly to strengthen up and eat healthier," Austan Torson, the owner and personal trainer at Miracles Fitness Retreat told E! News exclusively.

"I think it was a really good experience for her," Torson added. "She participated in everything we did. She was always up in the morning even though she was tired."
