How do muscles get stronger without getting “bigger”?

I can squat 10 more pounds than I could 6 weeks ago, but my body weight hasn’t changed. In the same vein, I’ve seen skinny dudes rip 300 pounds off the floor.

In addition to what others have said, there’s also an extent to which mitochondrial density and capilarisation are relevant. These matter much more for endurance than strength, and won’t make a significant difference to a (well-rested) 1RM effort. But if your rest is short, or you’re doing several reps, then it can make a difference.
