In this episode of the Dad Edge Podcast, Larry Hagner is joined by Oscar “Oz” Aponte—a U.S. Army veteran, StrongFirst kettlebell instructor, and founder of Iron Core—to explore what real strength means as a man, a father, and a leader.
Oz brings a powerful blend of physical mastery and spiritual depth, helping men move from brute force to intentional presence. Together, they unpack how posture, breath, nervous system regulation, and movement patterns shape your long-term vitality—not just in the gym, but at the dinner table, in your marriage, and in your legacy.
More than a conversation about fitness, this is a deep dive into fatherhood, grief, and building your life with intention. Whether you’re a kettlebell junkie or just a dad looking to show up better, this episode will challenge you to redefine strength on every level.

5 KEY TAKEAWAYS
1. Strength Is Presence
Being strong isn’t just about lifting weight—it’s about how grounded, aware, and calm you are with your family.
2. Your Nervous System Is Running the Show
Stress, posture, sleep, and breath all impact your strength more than ego lifting ever could. Master your internal world first.
3. Movement Is Medicine
Poor gait and posture don’t just cause pain—they drain your energy and shorten your lifespan. Train smart, not just hard.
4. Simplicity Wins
You don’t need a fancy gym or complicated gear. One kettlebell and intentional reps can outperform a cluttered workout.
5. Legacy Is Built in the Small Moments
Oz’s story shows that being a strong father isn’t about perfection. It’s about showing up, being present, and choosing intentionality every day.
