Wearing her fave “Wild Hearts” tee, Ashley Greene finishes up her workout on Tuesday afternoon (July 12) in Studio City, Calif.

The 23-year-old actress’ trainer Risa Sheppard opened up to MSN’s StarLounge about her fitness regimen.

“Ashley’s body is strong and flexible now,” Risa shared. “My method is an overall conditioning workout that encourages clients to work with their bodies and to realise their own personal perfection. It combines Pilates, therapeutic exercise, and body awareness.”

Risa added, “Ashley was very eager to learn how to use her body correctly so as to not have injury as well as to keep her body in tip top shape. Joseph Pilates says you feel good after 10 sessions, look good after 20 and have a new body after 30. With Ashley, I would say things started to change after 10 sessions only.”
