Ever since Greg Sterner was in high school, he knew he wanted to help people get fit, strong and stay that way. Greg decided to pursue his passion and graduated from Northeastern University with a Bachelor's degree in Physical Therapy. For the past ten years he has been helping people get in the best shape of their lives as a certified personal trainer through the American Council on Exercise (ACE) and a Nutrition Specialist through the American Academy of Sports Dietitians and Nutritionists (AASDN). In addition, Greg has also been helping people overcome injuries and obstacles to fitness as a Physical Therapist, with his elite certification as a Board Certified Orthopedic Clinical Specialist through the American Physical Therapy Association (APTA), a title only a small percentage of the country hold, as well as a Certified Strength and Conditioning Specialist (CSCS) through the National Strength and Conditioning Association. Greg was eager to take his knowledge and experience helping people one step further, and has recently opened Fitness Together, a one-on-one private personal training studio in the heart of Point Loma at Liberty Station. Fitness Together specializes in one-on-one workouts with your personal trainer in a private training suite, where clients can work on individual goals and where trainers are sensitive to special conditions, such as injuries. In addition to changing the lives of his clients, Greg has volunteered and spoken to senior groups on such topics as arthritis and physical training. He has also co-presented seminars in La Jolla and Aspen, CO on sports performance training for athletes in all realms of sports.

Training Manager NASM CPT UCSD Certificate of Fitness Instruction/Exercise Science UCSC BA Neuroscience and Behavior TRX Group Suspension Training Total Gym Gravity Certified Trainer

I started my fitness career after 3 years in the medical field. After working as a medical assistant I couldn’t ignore how many of our patients were being pushed drugs or surgeries as their only option when preventative medicine, a healthy lifestyle, and nutrition were not even discussed. After years of keeping this frustration inside I quit my job and went back to school to become a personal trainer.

A few years later, I am a NASM certified Personal Trainer with experience training a wide variety of clients including new/returning exercisers, active older adults, post surgery, those seeking weight loss/muscle gain, and advanced weight training. I take joy in my job and feel honored being allowed to be part of your health journey.

I have always had a passion for and been actively involved in a fit lifestyle. I was a competitive swimmer until age 20 and since then have kept busy with weight lifting, yoga, swimming, and the occasional 5k. It is not just something I preach to those I am training - I strive to lead by example and show my clients that with hard work, a positive attitude, and the right nutrition and exercise for your body, any goal is achievable!

When I’m not at Fitness Together, you can find me getting my own workout in, hiking with my boyfriend and our two dogs, or exploring San Diego’s amazing restaurant scene!

NASM CPT, Exercise & Holistic Lifestyle Coach C.H.E.K Institute

For me, coaching others to achieve their fitness and well-being is a personal and professional passion. My love of movement began at a young age and has continued into my adult life. I’ve played many different sports and activities including: baseball, football, Jiu Jitsu, and Olympic weightlifting. As I got older, I realized that I could emulate the same movements I loved so much playing sports, in the gym in what we call “functional exercise”. This gave me the freedom to move however I wanted without the limitations of playing a sport.

My passion for being physically active also led me to working different jobs prior to becoming a personal trainer. Some of the jobs include working as an emergency medical technician, landscaping, working on boats, and being a surf instructor. I’ve found that my experience in these different fields has benefited me as a personal trainer.

I am a certified (National Academy of Sports Medicine) Personal Trainer and a certified Exercise Coach and Holistic Lifestyle Coach through the C.H.E.K. Institute. In my free time, I like to be outside connecting with nature; hiking with my dog and close friends.

Improving one’s fitness and well-being through exercise is a lifelong pursuit that should be dynamic, effective, and fun. In addition to movement and exercise, I coach my clients on optimal nutrition and lifestyle practices. It is an honor to work with my clients to help them achieve their health and fitness goals.

Corrinne Sargent

NASM Certified Personal Trainer. NASM Corrective Exercise Specialist. TRX Certified

I got started in fitness because I have a true passion for exercise and what the human body is capable of. Growing up I was a competitive cheerleader for 10 years. While I was very active growing up, I had to learn how to workout on my own while in college. Like many, I gained some weight in college and I was intimidated of going into the weight section of the gym. After many trials and errors I learned how to navigate the gym, as well as balance a healthy and fit lifestyle working 40+ hours in a retail environment.

As a personal trainer I work with clients who are looking to improve their strength, achieve weight loss, build lean muscle, gain confidence or maintain their active independent lifestyle. I create individualized programs for all of my clients, and have experience working with a variety of injuries. I focus on the 5 foundational movements so the work you do in the gym translates to what you do in everyday life.

When I am not training clients or training myself, you can find me enjoying hikes with my husband, spending time with our dog and cat, or in front of the TV if it's football Sunday!

I have a passion for the fitness industry that started with my involvement in sports at a young age, continued through my years in the military, and culminated in the education I’ve pursued. I am committed to helping others achieve their goal, whether it is to lose weight, to be fitter or become stronger. I am reliable, motivated, empathetic and enthusiastic when working with clients. Whether I am one-on-one or in a semi-private class, I will tailor the workouts to my clients goals.

I have certifications that include NPTI-CPT, NASM-CPT, CPR/AED, and NASM-CES. I am also working towards my NASM-PES certification at National Personal Training Institute. Once I have completed the PES course, I will be pursuing an Exercise Science degree at Miramar College.

When I am not in the gym training clients or myself, I love exploring San Diego on hikes or hitting the beach playing Frisbee or Volleyball with close friends and family.
