Why are warm-ups considered beneficial
before hard labor or exercises?

A good warm-up will raise your body temperature, which is particularly helpful to your muscles.

Explanation: As your muscle temperature increases, oxygen becomes more available to your muscles, allowing them to contract and relax more easily – so you'll be able to perform more strenuous tasks with ease.
