Alvaro AKA Chief Acosta
I’m 34 years old and was born and raised in East Los Angeles, California. Like many others, I faced my share of challenges growing up and often found myself heading down the wrong path. Everything began to change when my twin brother enlisted in the United States Marine Corps. Watching his transformation inspired me to pursue a greater purpose of my own.
In 2012, I enlisted in the United States Navy, a decision that gave me the discipline, direction, and opportunity to become the man, leader, and father I strive to be every day.
I currently serve on active duty as a Logistics Specialist Chief in the United States Navy. Throughout my career, I’ve had the privilege of serving in Japan, San Diego, Lemoore, and now Port Hueneme, California. Each duty station has strengthened my leadership, resilience, and ability to perform under pressure while reinforcing the values of hard work, integrity, and service.
Beyond my military career, I’m a proud father to my six-year-old daughter, Camila Alicia, who is my greatest motivation and the reason I continually push myself to become better in every aspect of life.
My passion for fitness, discipline, and personal growth led me to earn certifications through NASM, ISSA, and ACE. Together with my twin brother, I co-founded EastSide Bull Athletics to help others transform not only their bodies, but also their mindset and lifestyle.
EastSide Bull Athletics is more than a coaching business—it’s a community and lifestyle brand built on discipline, accountability, resilience, and pride. Whether through personalized coaching or our apparel, our mission is to inspire others to embrace the process, overcome adversity, and realize that your past does not determine your future. With commitment, consistency, and the right mindset, lasting transformation is always possible.
