Osvaldo Aponte

Hi, I’m Os! I’ve been a personal trainer in San Diego since 2005, with a lifelong passion for movement rooted in my background as a martial artist, former contemporary dancer, and U.S. Army Veteran.

I specialize in helping people move better, get stronger, and feel more confident in their training—whether they’re beginners or seasoned athletes. As a StrongFirst Team Leader, I teach official workshops designed to introduce thoughtful fitness enthusiasts to the gold standard in strength training. I love creating a fun, focused, and empowering learning environment where participants can deepen their skills and walk away with real, usable tools.

Join me at one of my workshops—you’ll get stronger, learn smarter, and have a great time doing it.
