San Diego Core Fitness

At San Diego Core Fitness, we believe that fitness should be a journey, not a destination. We're not just a gym or a fitness studio; we're a community dedicated to helping you achieve your active passions and unlock your full potential. Our mission is to provide you with the tools, guidance, and support you need to succeed in your fitness goals and live a healthier, happier life.

Our founder, Justin Fassio, has over 27 years of experience in the fitness industry. He was originally certified as a Master Fitness Trainer by the U.S. Army in 1996 at Ft. Hood, TX. Over the years, Justin has modernized his training style but always followed one basic principle he gained as a Master Fitness Trainer for the U.S. Army: your workouts should enhance your performance in life. His functional training technique has conditioned soldiers and airmen to perform better in their combat roles.

Today, Justin is an ACSM Certified Personal Trainer and continues to inspire and motivate individuals to reach their fitness goals. At San Diego Core Fitness, we offer a variety of services designed to cater to different fitness levels and preferences. Whether you're a beginner looking to start your fitness journey or an experienced athlete seeking to improve your performance, we have something for everyone.

Our Services

We offer a range of services including live online fitness classes, nutrition coaching, and personal fitness plans. Our live online fitness classes are designed to be interactive and engaging, allowing you to participate from the comfort of your own home. These classes range from functional mobility and movement classes to strength and cardio class types. Each class is tailored to suit different fitness levels and goals, ensuring that you get the most out of your workout.

Our nutrition coaching program is centered around a 3-day juice fast. The goal of our nutrition program is to reset your digestive system and determine the diet that suits you best. Our 21-Transform nutrition program is designed to help you achieve optimal health and wellness by providing you with personalized nutrition advice and guidance.

For those who prefer personalized attention, we offer personal fitness plans. These plans are tailored to your specific fitness goals and preferences, providing you with a customized workout routine that you can follow at your own pace. Whether you want to focus on strength training, cardiovascular health, or flexibility, our personal fitness plans are designed to help you achieve your fitness objectives.

In addition to these services, we also offer micro workouts for clients who want to supplement their current routine or who lack the time to get a regular full-length workout in. These 15-minute high-intensity workouts pack a punch into a short timeframe, making them perfect for busy individuals who want to stay fit and active.
