I’m Cody Jensen, personal trainer and owner of The Fitness Code in San Diego. Since 2017, I’ve helped hundreds of people build strength, improve their fitness, and feel more confident in what their bodies can do.
I specialize in longevity training: developing the strength, cardiovascular fitness, mobility, and balance to keep doing the things you love as you age.
My approach is personal, practical, and built around consistency. We start with your goals, experience, and current abilities, then create a plan that challenges you appropriately and fits your life.
My own experience with debilitating back pain helped shape that philosophy. It deepened my commitment to understanding how to train through life’s changing circumstances and build lasting physical capability.
I’m certified through ISSA and PTA Global, with additional instructor certifications in TRX, Stick Mobility, and Landmine University. I continue learning because good coaching should keep evolving.
Outside the gym, I’m passionate about travel, exploring different cultures, and finding new adventures. I’m also a huge Lord of the Rings fan. Those interests reinforce why I train: I want the freedom and ability to keep experiencing the world. That’s what I want to help you build, too.
