Kobus van Zyl began his martial arts journey in South Africa, where he developed a deep foundation across multiple disciplines over several decades, coaching martial arts fitness classes at a local gym in his hometown, building programs that blended striking, conditioning, and functional strength. In 2008 Kobus achieved 1st place at the South African Kickboxing Championships, demonstrating high-level competitive skill and commitment. As a teenager, Kobus earned state colours in Olympic wrestling adding a strong grappling and takedown base to his striking background along with many years of weight training experience into his programming, with a strong focus on injury prevention, longevity, and real-world performance.

Moving to Ayr, Queensland Australia, Kobus continued his coaching career running kickboxing fitness and aerobics-style classes at two local gyms to help adults improve fitness and confidence. In addition, Kobus trained students in powerlifting, with two of his schoolboy lifters breaking the Australian schoolboys bench press record under his guidance. Expanded his reputation in Ayr as a coach who combines technical precision with safe, progressive strength and conditioning methods.

Kobus holds a 1st Dan black belt in Goshinkai kickboxing, brown belt in Shotokan karate, and 5th grade in Taekwondo, reflecting formal recognition of his technical level across striking combat arts. Kobus has competed in multiple martial arts disciplines over his career and is the current MKA Kyokushin heavyweight veteran NSW champion (2025/2026) and is currently practicing what he coaches by actively competing to keep his skills sharp and his coaching grounded in real competition experience gaining practical insight into striking, grappling, and full-contact combat formats.
