At the age of 16, I was 109 pounds, severely malnourished and in desperate need of change. Under the guidance of a dietician, I was told not only to increase my weight through healthy eating habits, but was also told to see a personal trainer. Working with a trainer, I was taught and educated on how to exercise safely and properly in order to meet a healthy weight. At 18, when I graduate high school, I was a proud 135 pounds. A

massive improvement from the past years. This is when I really discovered my love and passion for health and fitness. I thought that if I can go through the struggles of reaching my goa, then perhaps I can help others do the same. And thus began my long journey as a Personal Trainer.

I began discussing what I had learned throughout the last couple years begin with my trainer to friends and family, and over time began training them. Sure enough, they got the results they wanted, and began referring their friends and family to me. I couldn’t get enough. Hearing someone say to me how I’ve helped their self-esteem, confidence, or even improved their marriage and social life were good enough reasons for me to never want to pursues any other career.

I graduated from California State University, Long Beach in 2010 with a BS in Business Management with the intention of growing my Personal Training business. I am currently certified with the National Academy of Sports Medicine (NASM) as well as being CPR and AED certified.


"Brian has helped me a lot with my weight and posture during the time that he has been training me. I started working with him to help me lose weight and tone, but he pointed out issues with my posture during our initial assessment that we needed to address. Using his corrective exercise knowledge, he came up with a game plan that has given me great results with my weight and has helped alleviate the back pain I've experienced as a result of my horrible posture. If you're looking for a personal trainer, he's the best."

"I was traveling weekly to irvine,ca for business. I searched for a personal trainer to work with me during the week. After a little searching i found Brian. With this being my first personal trainer away from home, i was skeptical. When i met Brian and he asked the same questions as my other personal trainers, i knew hes good. I was there for 3 weeks and he was great! Just wish i could bring him back to dallas as my PT. He's very smart about recognizing how your body works and what should be worked on. He also is great and pushing you, and being the trainer that watches you and doesn't look around. Some other other items i noticed are, willing to get you the weights, mats, ie... not the other way around. Some of these tasks ive noticed some of my personal trainers skimp on. If i return to OC, im definitly looking up Brian again!"

"Brian Kranz has been a wonderful personal trainer. He developed a customized workout plan to help me build strength, stamina and lose weight. I have arthritis in my knees and ankles so physical activity was a challenge for me but after working with Brian the last 6 months, I am stronger and enjoy working out. The exercise also helped me reduce my medication dosage. Brian is supportive, kind and professional in his approach and I couldn't be happier with my newfound energy and strength. I wholeheartedly recommend Brian as a personal trainer."
