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.

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.

If elite male judo guys do bicep curls with dumbbells twice a week for six weeks—whether they go super fast with light weights, lift heavy until they can’t anymore, or go fast without pushing to failure—their biceps still get thicker and stronger, even during their competition season.

Lifting heavy weights three times a week for six weeks makes untrained young men much stronger than lifting light weights, even though both groups gain about the same amount of muscle size.

Lifting heavy weights until you can't lift anymore makes young male athletes much stronger than lifting light weights over 8 weeks, even if both make muscles grow about the same size.

Lifting heavy weights to the point of exhaustion three times a week for six weeks makes untrained young men much stronger than lifting lighter weights, even though both types of training build similar amounts of muscle size.
