What Our Clients Are Saying:

“I began working with Autumn while pregnant with my second child. As someone who worked in the fitness industry, I knew a lot about how to push myself, but was unsure how to continue exercising while keeping my baby safe. Immediately, I knew I had found the right person to guide me. Autumn developed a unique program that allowed me to continue working at a high level of fitness while maintaining a healthy environment for my growing baby. At 42 weeks, I was scheduled for an unwanted inducement. After a morning workout with Autumn, labor began within a few hours. I had a fantastic labor, delivering a very healthy and nearly 9 lb baby. After almost a year of training, at six months post-partum, I can honestly say Autumn continues to amaze me. Her workouts teeter on the edge between having a blast and thinking, "I don't think I can do one more". I frequently hear people tell me, "I can't believe you just had a baby." No question that Autumn is the reason for such compliments.”

“I have been working out with Autumn for a year and a half, maybe over 100 sessions. I Never GET BORED!!! She designs the workouts to be fun and makes sure I work at my max in every session. Autumn is very professional, knowledgeable and reliable. I suffer from a knee and ankle injury, I’ve tried several different trainers in the past and Autumn is the ONLY one I TRUST to work with. She has been able to help me loose weight and tone up more than any other trainer I have ever worked with. I strongly recommended trying Autumn or one of the other trainers from P3 Fitness!!”

--Pui Otero, Pacific Palisades, CA

“I have been working out regularly with Autumn for the past year. My husband and I are trying to conceive and when I do become pregnant I want to avoid gaining excess pregnancy weight, stay fit, and lose my pregnancy weight quickly after delivery, without all the drama of stretch marks, nausea, and fatigue. Autumn has been a great source of encouragement throughout this preconception phase. I have been working with her for a year now and the difference is amazing. She has transformed not only my physical appearance but she has also helped me to develop a new outlook on my life. I consider Autumn not only my trainer but my friend.”

--Jody Sandburg, Burbank, CA

"My husband and I have been training with Autumn for 3 years. Ironically after many years working out with big burly men my husband says Autumn is the only trainer that can make him have pain the next day! You got to love that! Autumn is upfront, honest, and a great mom herself! One of the hardest working women I know."

--Heidi Brooks

"I feel very lucky to have Autumn as my personal trainer. Her knowledge in fitness, specifically pre and post natal work, has been a gift. She began getting my body ready for baby the minute my husband and I decided the time had come. Using creative and interesting techniques, Autumn makes sure our workouts are never boring. She concentrates on strengthening key areas while keeping a watchful eye on my posture and breathing. In addition, her advice on nutrition when preparing for baby has been extremely beneficial. I have lost weight, gained muscle and feel healthier than I have been. Now, with baby on the way, I look forward to continuing my workouts with Autumn throughout my pregnancy. I am sure I will be in the best shape possible when the big day comes."
