There is a neurological tradeoff between being capable of fine motor skills or being able to recruit muscle fibers fully on short notice. Most animals get much more power out of their muscles, kilo for kilo, than a typical human, but few match us for devising novel, complex motions beyond the instinctual. We put everything into being able to speak and to make and use complex tools.

Repeated training does allow a human to recruit a greater share of the relevant muscle fibers into any given movement, but overall we will not match other animals for improvised general strength.
