Donna Armosino

Facility Manager

Personal Trainer at:
Rancho Bernardo, CA

Donna grew up in Chicago and later moved to Southern California. Her parents always encouraged her to stay active and she enthusiastically took their advice and participated in a wide variety of activities including softball, volleyball, gymnastics, and running. Running was one of her passions and, after a diligent training program, Donna went on to complete the Chicago marathon. That determination to achieve her goal, was one of her first steps in becoming a Personal Trainer.

Donna has always been enthusiastic about exercise and nutrition and she began to make it part her professional life by becoming a certified yoga instructor. She also continued her running and went on to complete numerous other races including two more marathons and two half marathons.

As a runner she began to feel like her knees were getting weaker. Fortunately, she discovered slow-motion strength training and has seen significant results. “I just love this workout. When I implemented it, my knees have improved so much that I have been able to run long distances again without pain.”

Donna quickly learned more about all the benefits of slow-motion strength training and changed her workouts to two weekly training sessions. With her highly active background and personal success with the method, Donna felt like helping others make the same switch felt like an exciting career move. She later found out about The Perfect Workout through a friend who worked for the company and knew she would be a great fit.

In 2013, Donna joined The Perfect Workout team and began training clients in the Rancho Bernardo studio. She is thrilled to have found a workout and career that brings so much positivity to other people’s lives. “I really enjoy being a part of my clients’ fitness journey especially when they achieve their goals.”

When one of Donna’s clients, Deborah Haight first joined The Perfect Workout, her goal was to lose 90 pounds. After working with Donna and the Rancho Bernardo team, one year later she achieved her goal of losing 90 pounds and feels and looks absolutely amazing!! “I love being a part of her transformation and in the process I made a life-long friend. Many of my clients have become friends -- I love all of them.”

With successes like Deborah’s, it was inevitable that Donna’s career would advance and she became the Facility Manager of Rancho Bernardo in 2015. “ I always hoped to manage the studio. I worked hard and learned everything from my previous managers.” To this day, Donna is leading the team and loving every minute of it.

“I love leading and guiding the other trainers! The trainers here are my family and I want to make sure they are successful both here in the studio and outside of the studio. I want to create future managers. I enjoy watching them learn and grow.” She prides herself on creating a wonderful and energetic environment in the studio where she and her team can work well together and provide their clients the best possible experience.” I will always be there for my team and my clients!”

Now that her knees are stronger than ever, Donna is running towards new goals. “My goal is to run the Rock’n Roll marathon in San Diego.” She loves to keep up with her running, as well as biking, hiking with her kids, and taking vacations to beautiful destinations!


Jen Walsh

Personal Trainer

Personal Trainer at:
Rancho Bernardo, CA

East Coast native, Jen Walsh has always had a love for food and fitness. She was a swimmer most of her life, played soccer and ran hurdles in track. After college, Jen moved to San Diego and shortly afterwards decided to pursue her love of cooking at culinary school. After graduation from the International Culinary School at the Art Institute, she got married and about a year later welcomed her first son. Looking for a way to be able to stay home with her baby and work flexible hours, she began her own Personal Chef company, offering clients a personalized meal service.

Jen’s love for fitness lead her to try all kinds of workouts including Kickboxing and other combat-inspired workouts but she noticed that her joints were suffering. She knew how important weight lifting was but felt that it was challenging to do while experiencing pain in her joints. When she found The Perfect Workout, it sounded like the perfect solution! Through the slow-motion technique, she has been able to reduce the pain she was previously experiencing, as well as gain strength and stamina to chase around her 2 young boys, who are budding athletes themselves.

Jen’s experience was so positive that she decided to pursue Personal Training and join The Perfect Workout team. Being able to infuse her background of fitness and personalizing her services to her clients made her a perfect fit for the Rancho Bernardo team.

“The Perfect Workout has proved to be the missing link in my own exercise routine, and I absolutely love working with my clients to provide safe, efficient, and quick workouts to help them lead healthier and more active lives.”

Adra Nelson

Personal Trainer

Personal Trainer at:
Rancho Bernardo, CA

Adra Nelson was born and raised in sunny San Diego. Growing up with four brothers, she became used to a life full of wrestling and sports, but picked up a few favorite hobbies of her own like volleyball, reading, snorkeling at La Jolla Cove, and hiking. Her active lifestyle created a passion for health and an interest in rehabilitation. Adra earned her Bachelor’s in Exercise Science from BYU and is currently working on her Doctorate of Physical Therapy at the University of St. Augustine for Health Sciences.

In recent years, Adra became very passionate about running. She would run 3-4 miles every day. After experiencing knee pain, one too many shin splints, and a loss of muscle and strength, she turned to weight training as a solution. She learned that The Perfect Workout provides the most safe, effective, and efficient workout method, and ultimately adopted the method. Now, she exercises twice a week with slow-motion strength training and no longer has joint pain from running, has increased muscle tone and strength, and has more time to pursue her hobbies!

Adra loves the way The Perfect Workout emphasizes injury prevention, which was the final push for her to get certified as a Personal Trainer and join the San Diego team. She intends to incorporate slow-motion strength training into her career as a Physical Therapist and continue spreading our mission to revolutionize the way people exercise. Adra encourages everyone to incorporate this method: “it can fit into anyone’s lifestyle, is efficient, and is safe for the joints.”

Adra is grateful to be spending her days working with clients at The Perfect Workout and helping them reach their goals while continuing her education so that she can better help those around her!

Aurelio Rosas

Personal Trainer

Personal Trainer at:
Rancho Bernardo, CA

Originally from North San Diego, Aurelio Rosas attended California State University East Bay where he received his Bachelor’s Degree in Sociology. Having been in love with strength training since high school, Aurelio decided to combine a love of fitness and his fascination with people’s motivational triggers into a career as a Personal Trainer. He joined The Perfect Workout in the S.F. Bay Area and later transferred down to Rancho Bernardo where he trains today.

Having the opportunity to work with clients 1-on-1 is one of Aurelio’s favorite aspects about being a Personal Trainer at The Perfect Workout. “My client has 100% of my attention and that really allows me to hone in on their form and what their needs for that particular day are. I believe it really brings value to their training session.”

Aurelio also values the emphasis that The Perfect Workout puts on safety while exercising, and truly believes that slow-motion strength training can work for anyone. “It is a great feeling to be told you were an integral part in changing someone’s life for the better, especially when they didn’t think it was possible.”

In his free time, Aurelio likes to enjoy the company of his family and friends. Outside of strength training, his biggest interest is cars, specifically, classic American muscle cars. One of his dreams in life is to restore a classic of his own one day.
