How Min Woo Lee Creates Tour-Leading Swing Speed at Just 165 lbs

If you’ve been watching the PGA Tour lately, you’ve probably seen Min Woo Lee absolutely bombing drives past players who are taller, stronger, and look more physically imposing. The question is: How does a 6-foot, 165 lb golfer generate 188 mph of ball speed—ranking second on the entire PGA Tour?

At Speed Toad, we love breaking down elite-level speed mechanics and efficiencies, and Min Woo Lee’s swing is one of the best examples of efficiency, training, and natural fast-twitch muscle talent working in harmony.

Why Min Woo Lee’s Swing Speed Defies Expectations

Conventional wisdom suggests that the taller and stronger you are, the faster you’ll swing. But that’s clearly not always the case. We compared Min Woo Lee to veteran PGA Tour player Matt Kuchar, who is 6'4", 195 lbs—and yet 27 mph slower in ball speed.

Both Min Woo Lee and Kuchar have some of the most technically sound swings in the world. So what gives?

The Key: Central Nervous System & Fast-Twitch Muscle Fibers

Speed isn’t just about strength—it’s about how fast your body can move. That’s where your central nervous system (CNS) and fast-twitch muscle fibers come into play. Min Woo Lee was likely born with incredible fast-twitch muscles and an incredibly responsive nervous system.

Think of kids on the playground—there’s always that one who just blows by everyone else. That’s not from training, 8 year olds aren't training, that’s natural God given fast twitch speed. The same principle holds true at the professional level.

Yes, You Can Train Speed Like Min Woo Lee

While Min Woo’s talent is elite, the good news is that you can train your nervous system to fire faster—just like he has.

This is the entire premise behind overspeed training, a method used by sprinters, baseball players, and elite golfers alike. By swinging something lighter than your driver (like our Speed Toad trainer), your body learns to move faster than it thought possible.

Over time, that increased speed reprograms your nervous system—so you swing faster with all your clubs throughout your bag.

Your Body is the Hardware. Training is the Software Update.

Think of your muscles as the hardware and your nervous system as the software. Overspeed training is essentially a software upgrade for your golf swing. Same body—better output.

Real Proof: World Record Club Speed
