Kids Martial Arts
Our Kids Martial Arts program helps children build focus, confidence, and respect through fun, structured training. Each class develops coordination, discipline, and self-control while teaching valuable life lessons that carry over into school and home. Students gain not only physical skills but the mindset to face challenges with courage and perseverance.
Adult Martial Arts
The Adult Martial Arts program combines traditional Tang Soo Do training with modern fitness and self-defense. Adults improve strength, flexibility, and mental clarity while relieving stress and building confidence in a supportive, goal-driven environment. It’s more than a workout — it’s a path to balance, empowerment, and personal growth.
Family Martial Arts
Our Family Martial Arts program brings parents and children together on the mat, training side by side and encouraging one another every step of the way. Families build stronger bonds, better communication, and healthier habits through shared learning and teamwork. It’s the perfect way to grow together — physically, mentally, and emotionally.
About Us: Building Strength, Confidence, and Community Through Tang Soo Do
At Yi’s Karate Institute in Sewell, NJ, everything we do is rooted in three timeless core values: Respect, Discipline, and Growth. We believe that true martial arts training extends beyond physical skill — it’s about building character, leadership, and confidence that last a lifetime. We stand for Character Before Rank, Family and Community, and Lifelong Learning, ensuring every student, from the youngest beginner to the most seasoned black belt, feels empowered to become the best version of themselves both on and off the mat.
Just as importantly, we stand against ego, negativity, and quitting. In our dojo, we believe that progress is earned through humility, consistency, and an open heart. As we like to say, “A true black belt isn’t measured by the color around their waist — but by the strength of their character when no one’s watching.” Whether you’re looking to help your child gain confidence, get fit yourself, or share something meaningful as a family, we invite you to experience Yi’s Karate Institute for yourself.

Self Defense Skills
Every student at Yi’s Karate Institute learns practical self-defense techniques rooted in traditional Tang Soo Do and adapted for real-world application. Training builds awareness, confidence, and the ability to stay calm and make smart decisions in any situation.
Increased Mental Clarity
Through focused drills, forms practice, and mindful repetition, students sharpen concentration and clear their minds of distractions. Each class becomes a mental reset — improving decision-making, memory, and focus both on and off the mat.
Stress Relief
Our classes offer a healthy outlet to release tension and recharge. Whether through focused movement, controlled breathing, or the rhythm of training, students leave each session feeling refreshed, grounded, and more centered.
Improved Physical Fitness
Every class at Yi’s is a full-body workout designed to improve strength, flexibility, endurance, and coordination. Students develop lean muscle, better posture, and lasting energy — all while learning powerful martial arts techniques.
Greater Self Confidence
As students set goals and earn new belts, they see firsthand how consistent effort leads to achievement. That success translates into everyday confidence, empowering them to take on challenges with courage and pride.
Community Interaction
Yi’s Karate Institute is more than a school — it’s a family. Students of all ages train together, encourage one another, and build friendships rooted in respect, teamwork, and shared growth.
“True strength isn’t proven in combat — it’s built through the quiet discipline of showing up, improving, and never giving up.”
We Believe in the Power of Character
At Yi’s Karate Institute, we believe that who you become is just as important as what you achieve. Every kick, block, and form is an opportunity to practice patience, humility, and perseverance. Our instructors emphasize that respect and integrity are not confined to the mat — they should guide every action, word, and decision in daily life. By nurturing these values, we help students develop a moral compass that serves them far beyond their martial arts journey.
We Believe in Lifelong Growth
The journey at Yi’s Karate Institute never truly ends — it evolves. From the moment a student ties their first white belt to the day they earn their black belt and beyond, each step is a chance to grow stronger and wiser. We teach that progress isn’t about perfection but persistence — small, consistent efforts that create lasting transformation. Our community thrives on this mindset of continuous improvement, where every student, regardless of age or rank, is encouraged to keep learning, striving, and becoming better every day.
