Most would simply assume that you should only wear compression gear when you are actually working out. Well, while that is an ideal time to wear it, you can also wear it beforehand. What this can do is prepare your muscles for a big race, for example. Without going into full detail, compression tights can accelerate the warm-up process and reduce your risk of injury. Of course, as mentioned, wearing them during your workouts and runs will be beneficial. One of the main things they will do is reduce your muscular vibrations while you run and this will lessen the chance of injury and increase your overall performance.
