What We Work On

Private boxing sessions focus on building strong fundamentals while gradually developing more advanced skills.

Training may include:

  • Proper stance and balance

  • Footwork and ring movement

  • Punching mechanics and combinations

  • Head movement and defensive awareness

  • Blocking and parrying techniques

  • Mitt work and technical drilling

  • Heavy bag training

Each session builds on the previous one, helping students develop both technical skill and physical conditioning.

Defense First Boxing

My coaching philosophy emphasizes defense before offense.

Students begin by developing strong fundamentals including footwork, head movement, blocking, and parrying. Only after these skills are established do we begin building offensive combinations and strategic ring movement.

This approach produces boxers who are technically sound, adaptable, and capable of continuing to develop over time.

Defense-first training not only improves performance but also helps students train safely while building confidence in the ring. This approach produces smarter, more technically sound boxers.

Students develop:

  • Footwork

  • Head movement

  • Blocks & Parrys

  • Defensive awareness
