What is the purpose of a warm-up before an exercise session?

The purpose of a warm-up before an exercise session is to prepare the body for physical activity and prevent injury. Warming up gradually increases heart rate and blood flow to the muscles, enhancing the delivery of oxygen and nutrients necessary for optimal performance. It also increases muscle temperature, which improves elasticity and reduces the risk of strains and sprains during more intense exercise.

Additionally, a proper warm-up often includes dynamic stretches that promote joint mobility and further ensure that the body is adequately prepared for the specific movements that will occur during the workout. This proactive approach not only helps in injury prevention but can also improve overall exercise performance, making it an essential component of any fitness regimen.
