How do muscles get stronger ?

There's obviously the whole hypertrophy system which i'm well aware about but i'm guessing there's more than that otherwise bodybuilders would be the best powerlifters.
I guess my question would be what make muscles stronger, excluding muscles getting bigger ?

As you exercise, your nervous system becomes more efficient to activate the relevant muscle fibers to perform your action, like a plant growing in the direction where sunlight is most often found to maximize energy production. On top of this, your body adapts by producing more muscle fibers and mitochondria(Chemical energy producers) within the relevant muscles so that they are more equipped to perform actions of similar intensity. This is why bodybuilders and powerlifters progressively increase their weight over time.

But your muscles and nervous system aren't the only systems which adapt to strength training. Your bones become more reinforced and resistant to diseases such as osteoporosis and synovial fluid lubricates your joints to keep internal friction down. Your heart also becomes more efficient with each pump and its endurance(Especially in the case of aerobic sports such as running and swimming), along with the rest of your respiratory and circulatory system(By increasing red blood cell count and the amount of capillaries in muscle tissue.)
