Which statement is true regarding warm-ups?

Warm-ups usually last 5-10 minutes, which is the recommended duration to prepare the body for physical activity. This brief but essential period allows for gradual increases in heart rate, circulation, and muscle temperature, all of which help improve performance and reduce the risk of injury during more intense exercise.

A warm-up typically includes light aerobic activity and dynamic stretches, both of which help loosen joints and increase blood flow to muscles. A duration of 5-10 minutes is generally sufficient to achieve these benefits without causing fatigue before the main workout or competition.

The other statements about warm-ups are less accurate; for example, warm-ups are not optional if one wants to ensure a safe and effective workout, and they do not need to be excessively long as seen with the 30-minute claim. Furthermore, anyone can achieve physical fitness through consistent activity regardless of being classified as an athlete.
