No one is exactly like you.  That’s why we customize our program for each of our clients. What does this mean?

  • If you have unique physical requirements, we work within those specifics. (NOTE: Please be sure to consult with medical professionals providing your care before starting any physical fitness program.)

  • If your work schedule only permits specific times for you to invest in your physical fitness program, we work with that.

  • If you have specific financial concerns about investing in your physical fitness, let’s talk about how to accommodate your particular budget.

  • Whatever your specific set of circumstances are, most likely, we can find a way to work with them.

In return what do we ask of you?

  • A commitment to do the recommended “homework” we give to you, our physical fitness student.

  • A conscientious attitude about doing your best (within any physical limitations that may be a concern to you)

  • Showing up! That means no unreasonable excuses about why you no longer want to build a healthy body to serve your needs while living!

What People Are Saying

“I am in the best shape of my life, feeling confident and half way to my goal of losing 40 pounds, thanks to Kevin! He is an inspiring, highly skilled trainer who is masterful at individualizing my training to my needs and meeting me where I am at. He also pushed me to be my best self, and is simply a delightful person to be around – he makes it fun!”

Erika V

“Kevin is a fantastic trainer!! His positivity, creativity and knowledge are superb. I used to go to the gym wondering what do I do for strength training. Even though I am motivated I lacked a plan and was never sure if I had proper form when I was doing a specific exercise, or how much weight a machine should be set on. Kevin always has a specific plan for me when I train.

Dawn H

“Earlier this year I signed up for a mud run at Camp Pendleton. Never done a mud run before so I decided to train with Kevin for a few  months. We did circuit training and weight training. I really enjoyed each session with him. He has a great personality. He’s also a great motivator and encourages. I completed my mud run this past weekend. ” 

Cecilia L

“Kevin has been mine and my husbands personal trainer for almost 2 years. He has now become our family member. He has changed our bodies, our mind set and our health for the better. He is flexible when your schedule changes, he listens to when you have problems, he listens to areas that you really want to target. I am starting to be more proud of my body every day. ”
