Warming your body up prior to exercise is beneficial for several reasons. One of the main reasons it is important to take the time to warm your body up prior to exercise is for injury prevention. Increasing your body temperature prior to exercise reduces your chances of muscle and tendon injuries. The more oxygenated blood flow and circulation you have to your muscles prior to use, the more agile they will become causing the margin for injury to decrease significantly. Warming up can also help activate your joints, tendons, and ligaments which will help increase your range of motion during exercise. An example of a warmup would be a brisk 5-10 minute walk on the treadmill.
