We have a Core Fitness Personal Trainer ready and available for you Virtually or In-Person at one of many outdoor locations in San Diego.

Whether your fitness goal is to lose weight, gain strength or just look great at the beach, we have personal trainers in Sand Diego or Online standing by.

Why San Diego Core Fitness?
We have developed a system of Cross Functional Training that will improve your fitness for all other modes of exercise whereas other types of exercise won’t improve upon your performance in our boot camps. It took years to perfect but it stems from the training Justin received in the U.S. Army running the PT program for his TACP unit at Ft. Hood, TX.

Personal Fit Plans

This is one of our favorite programs to administer. It’s all about data and tracking. We create a custom Core Fit workout in a PDF and go over the exercises via a live virtual appointment. We record the virtual session and attach the PDF workout to it so you have it in both written and video format. Next, you choose a nutritionist approved meal plan in our nutrition software and enter your daily meals. We review and adjust week-to-week to make sure you are always moving forward towards your goals. This is program is unique to SD Core Fitness, you won’t find it anywhere else.


I often get bored with workouts, especially in the gym, but for TWO YEARS I have been trained, challenged, encouraged, entertained and surprised by how enjoyable (but hard!) Justin’s workouts are. If you sign up for multiple locations, you hit the jackpot. His wife, Rachel, teaches some of the TOUGHEST most cardio-riffic classes I’ve ever tried. Combined, they are the workout dream team.

I’m 38 and the thought of boot camp would send me running, the other way. But I figured, heck, why not. It is the best purchase I’ve ever made!! You can do it, no matter age, lifestyle, body type, doesn’t matter. It’s so worth it. I love the Morley Field location, I’m just so happy I was brave enough to take the step, way forward.
