What does the term "warm-up" refer to in fitness?

The term "warm-up" refers to preparation for intense exercise. This phase is crucial in any workout regimen as it helps to gradually increase the heart rate and improve blood flow to the muscles, creating a safer environment for physical activities. During a warm-up, the body begins to adjust to the demands of the upcoming workout, which can enhance performance and reduce the risk of injury.

Typically, a warm-up includes light aerobic activities and dynamic stretching aimed at engaging the muscles that will be used in the primary workout. This not only helps physically prepare the body but also mentally primes the individual for the exercise ahead. By easing into more vigorous activity, the transition from rest to exercise becomes smoother, enhancing overall effectiveness.
