When young male athletes lift heavy weights until they can't anymore, they get much faster at generating power quickly, but this doesn't happen with lighter weights.

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.

When you lift heavy weights, your muscles get faster at producing force quickly, but lifting lighter weights doesn't help much with this. It means your body responds better to heavier loads for getting stronger faster.

In moderately trained adults, lifting heavy or moderate weights improves movement speed across all lifting intensities, while explosive training does not produce the same effect, suggesting that strength and muscle-building workouts can enhance speed even at lighter loads.

Lifting heavy weights until you can't lift anymore makes young male athletes much stronger than lifting lighter weights over 8 weeks, showing that heavier loads train muscles and nerves better.

When trained men lift heavy weights using certain training styles, they spend more time under tension and generate more force per rep than with other styles, which might help them get stronger.
