| ✕ Cross your fingers and hope the instructor notices your child. | ✓ Personalised and individual attention from coaches. All classes are beginner friendly. |
| ✕ Try a class. Get pushed into a 12-month contract. | ✓ No contracts. Take a break whenever you need. |
| ✕ Get stuck learning from instructors using outdated techniques, that have never been tested in competition. | ✓ Learn from instructors who have proven their skills in professional boxing, MMA and Jiu Jitsu. |
| ✕ Little emphasis on building character, discipline, and resilience in children. | ✓ Our kid-focused curriculum emphasises discipline, resilience, and personal growth alongside technique. |
| ✕ No structured progression or belt system to keep kids motivated. | ✓ Clear belt progression system that gives kids goals to work towards and rewards their effort. |
| ✕ Team selections and risk of exclusion or “benching” for children who may not be as naturally talented. | ✓ All children master new skills and earn belts, forging unwavering self-confidence and belief in their own capabilities. |
