She's the wo-man! Formerly troubled star Amanda Bynes looked fit, healthy, and radiant while exiting a training session at Cardio Barre in Los Angeles on Wednesday, May 28. 

The She's the Man actress, 28, wore flip flops, black leggings, and a black T-shirt with a snakeskin purse and shades. Bynes wore her blonde locks down and wavy, smiling wide as she exited the studio. 

The Fashion Institute of Design and Merchandising student is one of many celebrities who uses the Cardio Barre studio. On their official site she wrote a testimonial about her time there, saying, "I have been coming to Cardio Barre for 6 years. It is an amazing workout that tones, tightens, and is so fun at the same time! I am a huge fan!" 

Other stars to frequent the location include Ashlee Simpson, Dakota Fanning, Jenna Elfman, Melissa Joan Hart, Stacey Dash, and Megan Hilty

Bynes left rehab in December 2013 after an extended stay for mental health issues. Since her time away, the former child star has reconnected with her family, posting several photos with them on her once-infamous Twitter account.
