Every living being is born with a certain genetic limit that constrains one's strength. Studies suggest that we are unable to reach our maximum potential due to the limitations in our brains.
For example, in extremely life-threatening situations, individuals may find that their strength is instantly increased and they can perform actions that would be impossible in their normal state.
However, even when one's body reaches its maximum potential and they can exert their strength to the extreme without the restriction of the brain, it is still limited. For instance, they may not be able to lift a building.
At most, during critical times, their strength is slightly increased, but it remains within the range of what a trained professional could achieve.
No matter how intensely one trains to condition the body, there is still a genetic limit that is specific to each individual.
