You’ve seen the photos. Maybe you saw him flying across the screen in Cobra Kai Season 6 as the formidable Kwon Jae-Sung, or perhaps you caught his viral stunts in the League of Legends World Opening Ceremony. The first thing most people notice about Brandon H. Lee—besides the terrifyingly fast spinning hook kicks—is the midsection. It isn't just a "fitness model" six-pack. It’s that dense, functional, "armor-plated" look that usually only comes from a lifetime of combat sports.
Honestly, everyone wants to know the "secret" to the Brandon H Lee abs look. People search for the specific rep counts and the magic exercises, hoping there’s a shortcut hidden in a 10-minute YouTube video.
But here is the reality.
Brandon isn't just a guy who hits the gym to look good for Instagram. He’s a 5th Degree Black Belt in Taekwondo and a U.S. National Champion. When he trains his core, he isn’t thinking about beach season; he’s thinking about the rotational torque needed to snap a kick into a target with enough force to end a fight. That distinction changes everything about how the muscles actually develop.
The Martial Arts Foundation vs. Traditional Bodybuilding
If you look at Brandon's physique, it’s chiseled but lithe. It’s "jungle cat" lean, much like the legendary Bruce Lee—a comparison that isn't accidental. In fact, Brandon has openly filmed himself tackling the infamous Bruce Lee ab routine, including the dreaded Dragon Flag.
Most gym-goers train their abs through "crunching" movements—shortening the distance between the ribs and the pelvis. Martial artists like Brandon do the opposite. They focus on anti-rotation and explosive rotation.
Think about a spinning kick. Your core has to act as a rigid bridge to transfer power from the ground, through your hips, and out to your foot. If your core is "soft" or only trained for 12 reps of slow sit-ups, that power leaks. The density in Brandon's midsection comes from holding high-tension positions while moving other limbs at high speeds.

What a Brandon H Lee Abs Routine Actually Looks Like
While he hasn't released a "one-size-fits-all" PDF, we can piece together his philosophy from his training at Lee’s Champion Taekwondo Academy and his stunt prep videos.
He doesn't do boring.
The Power of High-Rep "Shield" Training
Brandon often references the idea of the core as a shield. This means high-volume conditioning. We're talking:
- Hanging Leg Raises: Not just bringing the knees up, but full toes-to-bar movements to engage the deep lower abdominals.
- Russian Twists: Performed with speed to mimic the "snap" of a martial arts strike.
- V-Sits: Holding the "V" position for time, often while performing other movements like punches or blocks to force the core to stabilize under chaos.
The Dragon Flag Obsession
You can't talk about Brandon's core without mentioning the Dragon Flag. This is the move where you lie on a bench, grab the top, and lift your entire body into a straight line, supported only by your shoulders. Then, you lower yourself slowly without letting your back touch the bench.
It is incredibly hard.
Most people fail this because they try to use their legs. Brandon uses his entire posterior chain and core to "stiffen" the body. It’s a total-body tension move that builds that deep, "cut" look that superficial crunches never will.
The "Action Movie Prep" Reality
In his recent "Action Movie Prep" vlogs, Brandon shows the grind. It's not all sunshine and highlights. He talks about jet lag, the mental fatigue of "resetting" for a scene 50 times, and the discipline required to keep training when you're exhausted.
Visible abs are a byproduct of a low body fat percentage, which for Brandon comes from a massive caloric burn. Between hours of Taekwondo forms (Poomsae), stunt choreography, and traditional strength training, his metabolic rate is likely through the roof.
He isn't starving himself. He’s fueling a machine.
He’s mentioned eating high-protein meals to maintain muscle mass during intense filming schedules. If you want his look, you can't just do the leg raises; you have to do the "boring" work of managing your kitchen. It’s basically 70% what you eat and 30% how hard you can brace your spine.

Why You Probably Can't "Copy" His Routine Exactly
Here is the nuance most "fitness influencers" won't tell you. Brandon H. Lee has been doing Taekwondo since he was three years old.
Three.
That is over two decades of neurological adaptation. His brain knows how to fire those core muscles more efficiently than someone who started lifting at 22. When he does a simple crunch, he’s likely engaging more muscle fibers than a beginner doing a "harder" exercise.
Also, his flexibility plays a role. High-level Taekwondo requires extreme hip mobility. When your hips are mobile, your core can function better because it’s not fighting against tight hip flexors or a locked-up lower back.

Actionable Steps to Build That "Brandon H Lee" Core
If you want to move toward this specific look and level of function, you have to stop thinking about "abs" as a separate body part you train for 5 minutes at the end of a workout.
- Prioritize Static Holds: Incorporate L-sits, planks with weight, and hollow-body holds. Aim for 60 seconds of "perfect" tension. If you're shaking, you're doing it right.
- Learn to Rotate: Add woodchoppers or medicine ball rotational throws. The goal is to be explosive. Move the weight as fast as possible while keeping your feet glued to the floor.
- The "Slow" Dragon Flag Progression: Don't just jump into the full move. Start with "candlestick" raises where you tuck your knees. Slowly work on lowering your legs while keeping your back off the floor.
- Clean Up the Diet, but Keep the Protein High: You need the "cut" to see the work. Focus on whole foods—chicken, fish, rice, greens. Brandon stays lean because his activity level is insane, but if you're a desk worker, you have to be much more calculated with your macros.
- Mobility is Non-Negotiable: Spend 15 minutes a day on hip and thoracic spine mobility. If you’re stiff, your abs can’t reach their full range of motion, and they won’t develop that "full" look.
Stop looking for a shortcut. The reason Brandon H. Lee has the core he does is that he spent years perfecting the movements that the core is actually designed for. Move better, eat cleaner, and train with more intensity than you think you need.
