How do muscles get stronger without getting “bigger”?

Question

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.

Answer 1

Muscle recruitment. You only use so much of your muscles when you’re working out. As you use them more, your neurons get better at talking to that muscle, and you can get more of those muscle fibers to fire.
