"Warms up" is a phrasal verb that is commonly used in several contexts. Here are a few examples:
1. Exercise: "Warm up" is often used in the context of physical exercise or sports. It refers to the process of preparing the body for a more intense physical activity. This can include stretching, light aerobic exercises, or simply doing a less intense version of the desired activity. For example, before running, it is advisable to warm up by doing some jogging or brisk walking to increase blood flow and loosen up the muscles.
2. Music and performing arts: In the context of music or performing arts, "warm up" refers to the process of preparing one's voice or body before a performance.

4. Social interactions: "Warming up" can also pertain to social situations, especially when meeting new people or entering a different environment. When someone is initially reserved or shy but gradually becomes more relaxed and engaging, we can say they are "warming up" to the situation or the people around them.
So overall, "warm up" can refer to physical preparation, such as exercises or stretching, getting ready for a performance, a gradual increase in temperature, or becoming more comfortable in social situations.
