About Me
Hi, I'm Martha McKenna—Certified Personal Trainer and founder of LOCKD Fit. I am an undergraduate student at Boston University studying business, but my home is in San Diego. I am passionate about fitness, politics, fashion, and horses. I competed in national showjumping events for ten years before going to school on the East Coast.
My Story
In the sixth grade, my weight and BMI indicated obesity. It wasn't until I recognized the consequences of my unhealthy behaviors that I was determined to make a change in my lifestyle. Thus, my first fitness goal was born. In one year, I lost fifty five pounds and since 2019, health and fitness have been some of my greatest passions. Through research, I learned and developed my knowledge and skills in exercise planning, technique, and recovery. Soon after, my friends and family started asking questions, and I realized I had a lot to offer. I’ll never forget the moment my sister nailed a Romanian Deadlift with perfect form—that “AHA!” moment lit a fire in me and I fell in love with training. Since then, my passion has evolved into purpose. What started as a personal journey has grown into a mission to help others feel confident, capable, and strong in their own skin. Now, as a Certified Personal Trainer, I dedicate my experiences and knowledge to guide others toward sustainable change—built on education, support, and intentional movement. Whether you’re just starting or looking to level up, I’m here to walk with you every step of the way.
