About Debby

I have been a fitness instructor since 1999 and worked at many different gyms: LA Fitness, Bally Total Fitness, 24 Hour Fitness, YMCA, Linda Evans Fitness Canter, and tThe Spa for Women. I teach many different formats for many different fitness levels using a variety of modalities. These classes include: step, high-low, power flex or body pump, aqua circuit, HIIT, and body ball classes. I also have several certifications through ACE: personal training, group fitness, group training, and corrective exercise. I have also accomplished a Kinesiology degree from Cal State University of Dominguez Hills. The YMCA is my current location of employment where I teach aqua, total fit, body pump, and circuit, along with personal training. I love what I do and I love helping other people feel better about themselves as they improve their quality of life.

My favorite exercise

I love to work on core, because if the core is strong then all my movements can be strong.

My favorite quote

Trust in the Lord and leave all the consequences to Him.

My training philosophy

Train in a way that prepares one for life, train in a way that increases quality of life, and train in a way to decrease the chance of injury or sicknesses.

My training experience

Over the years I have changed my body to become more functionally strong and conditioned my cardiovascular system to be more and more efficient.

Debby Hartman trains me twice a week. Thirty minutes seems to be right for me. First I warm up for a half hour on the recumbant bike and am slowly adding time on the elliptical. Debby works on strength, balance and endurance with me. I’m 76 and have a knee replacement so there are things I cannot do but Debby finds ways around my limitations with humor and ingenuity! *****

Great trainer, always encouraging and keeping it new. I just started and I'm loving it. I would highly recommend Debby as a trainer.


Debby is an amazing fitness trainer, she is pleasant and knows the training equipment to help you get in shape. Debby explains how to use the equipment and what it does for you. I highly recommend Debby Hartman for your personal trainer, she is the best I have found.

Debby does an excellent job of challenging, encouraging, correcting gently (as I am terribly uncoordinated with no muscle memory!) I feel like I've improved in strength, conditioning and balance while working with her.


I have to say my training session with Debbie was outstanding. I had another trainer earlier, he seemed to make it up as we went along. Debbie & I had a meeting prior to the training we discussed some of my personal limitations and what I was looking for. The training she gave me seem to be specifically designed for me. You could tell she put some serious thought into it before we started. I will definitely use her again in the future

Looking for a trainer that is knowledgeable, pleasant, knowledgeable and patient, knowledgeable and motivating? Debby Hartman is the trainer for you. If Mary Poppins was writing this review she would write that Debby is "Practically Perfect in Every Way!” No, I am not Mary Poppins; I am a senior citizen with Multiple Sclerosis. And, I think Debby is the Best. Many Thanks.
