If super strong male judo guys bulk up more with heavy weight training, they might actually get less powerful for their size, meaning bigger muscles don’t always mean better performance.

Resistance training leading to repetition failure increases muscle strength and size, but not power-generation capacity in judo athletes

Randomized Controlled Trial

Human

2024

The study found that even though the athletes' muscles got bigger and stronger with heavy training, their power didn’t improve—meaning bigger muscles didn’t translate into better performance, which supports the idea that too much size might not help and could even hurt efficiency.

Similar Assertions

Even if elite male judo athletes lift weights for 6 weeks, it doesn’t seem to make them more explosive — getting stronger or bigger muscles doesn’t necessarily help them punch or throw faster.

For male judo athletes who are already pretty advanced, lifting heavy weights for 6 weeks might build more muscle and strength than doing fast, light lifts—even if both workouts push muscles to the max.

Getting stronger from lifting weights doesn’t always mean your muscles are getting bigger—and vice versa. Strength and size don’t go hand in hand.

For elite male judo players, doing explosive strength training with light weights—without pushing to the point of exhaustion—works just as well or even better for building muscle and strength than going until their muscles give out.
