Similar Assertions

When untrained young men lift heavy weights (80% of their max), their muscles and nerves become more efficient at lighter tasks, needing less effort over time. Lifting lighter weights (30% of max) doesn't give this same benefit.

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.

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.
