"My one trainer helped me lose a sh-t ton of weight. I lost like 30 pounds. His name is Gabe Johns and he is amazing. He's a boxing trainer and he comes to my house. I live in the canyon, so we just run. He runs my ass up and down the hill," Duff revealed in February, adding, "We do some circuit stuff and boxing, which is a lot of fun and you get out a lot of sh-t that way. The other trainer I want to give a shout out to is Vivica, and she has been my Pilates instructor for like seven years. And Harley Pasternak, who is like a genius. He is a sculpting genius."
