Breathing in the toxic smoke can be harmful to your lungs, and the health and safety of our students and families is our top priority.

Sensei Says:

Massive congratulations to our 14-year-old Jose Arreguin, the unstoppable force who clinched victory at the Summer Junior Olympics in boxing! 🥇 Every jab, every hook, every drop of sweat in training led to this well-earned triumph. Jose, your heart, skill, and determination have truly set you apart—what an incredible moment for you and everyone cheering you on!

Huge props to Coach Dylan Kowalski, the ultimate cornerman and mentor. Your guidance, strategy, and calm confidence in the corner helped Jose perform at his absolute best. Every champion needs a coach who can see the fight inside and out—and Dylan, you nailed it.

A special shoutout to Jose’s teammates, whose encouragement, sparring sessions, and unbreakable support created the foundation for this victory. Boxing isn’t just about fists—it’s about community, and Jose’s team delivered every single time.

And let’s not forget the powerhouse behind the power—the Beast boxing program at Underground Boxing! This program builds champions through world-class training, relentless discipline, and a culture that pushes athletes to exceed their limits. Jose’s win is a shining example of the excellence this program cultivates.

Jose Arreguin, you’ve made history, inspired your peers, and shown the world what dedication looks like in action. This is only the beginning—keep punching, keep shining, and keep making us all proud! 🥊💥
