Narushima Koga didn’t start out strong.
He built his body—and his fighting style—through pure grit and relentless effort.
His journey from a skinny street brawler to a recognized professional fighter in the Kengan world reflects one thing: work capacity and constant progression. Koga’s training is all about explosive strikes, quick footwork, and the endurance to outlast stronger opponents.
This workout plan reflects that evolution.
Using calisthenics, dumbbells, jump rope, and kettlebell-based conditioning finishers, you’ll build striking power, agility, and fighter-level endurance—all without needing fancy gym equipment.
Whether you’re chasing speed, lean muscle, or just want to train like a real-world fighter, this program will help you develop the mindset and physical edge Koga fought for.
Let’s get to work.

Training Principles
1. Explosive Striking Power
Koga’s transformation into a high-level striker came from focusing on fast-twitch muscle recruitment and upper body explosiveness. His punches, elbows, and short-range attacks are all powered by quick, forceful contractions.
In Practice:
You’ll use exercises like dumbbell push presses, explosive pushups, and floor presses to develop the speed-strength needed for striking. This isn’t slow, heavy lifting—it’s about moving weight fast.
2. Agility and Fight-Ready Footwork
Koga’s fight style requires constant repositioning and quick foot resets. Whether darting in for a combo or slipping a counter, his training emphasizes lower body speed and reaction time.
In Practice:
You’ll hit jump rope sprints, lateral bounds, and quick-foot drills designed to build multi-directional agility and fast reaction timing.
3. High Work Capacity and Endurance
Koga often fights stronger or more experienced opponents. To survive, he built a motor that lets him throw volume strikes and pressure for extended rounds.
In Practice:
This plan includes minimal rest intervals, jump rope-based conditioning, and high-rep bodyweight supersets. The goal is to boost both muscular endurance and cardio output.
4. Rotational Core Power for Striking
Every hook, cross, or body shot starts from the core. Koga’s power doesn’t come from his arms—it comes from rotational torque generated through the hips and torso.
In Practice:
You’ll see Russian twists, plank-to-knee drives, hollow holds, and side bends programmed to build a core that creates and transfers force with every movement.
5. Minimalist Tools for Maximum Output
Koga’s journey reflects building strength without excuses or fancy equipment. That’s why this plan sticks to calisthenics for movement skill, dumbbells for load, jump rope for conditioning, and kettlebells for fight-finisher burnouts.
If you’re serious about training like Koga… expect to move fast, push hard, and finish strong.
