"Obviously, the whole thing was a prank and shared in good fun. Schumer even made it a point to note that Fisher is actually an "amazing" trainer. "[She's] the reason I feel strong and good and have recovered from my herniated discs and C-section," Schumer wrote.  - FAITH BRAR for SHAPE magazine

"For the last three years, I've worked out with my trainer AJ Fisher, three or four times a week. I started working with her when I got the role of Okoye. I was about to go into pre-production, and I felt like I needed to amp up my fitness and endurance. I call her the MacGyver of trainers because she can create an elaborate course in your living room with just a coffee table and a couple of resistance bands. She mixes things up--it's never the same workout, so your body can't get used to it."  - DANAI GURIRA speaking to SHAPE

"When she needs to kick her training up a notch, she schedules sessions with her longtime trainer, AJ Fisher. Rooted in a precision method she created, Fisher’s workouts focus on balancing muscle function and boosting strength and flexibility. The technique is especially beneficial for Lauren, who suffers from achy hips and lower back pain from a herniated disc after being rear-ended twice and injuring her tailbone when she fell while waitressing back in her 20s. Through it, she learned to do muscle activations before starting cardio: deep exhalation ab exercises and engagements of the muscles on either side of the spine to “turn on the right muscle to walk,” says Lauren. Exercising is less painful because of these small movements.."

I do some form of exercise. I have so many injuries, I’m pretty much an orhopedic nightmare. I work with AJ Fisher of, who is really patient and intelligent about how not to get hurt. Otherwise I go to a yoga class.
