The best type of stretching to perform before exercise is dynamically based stretching. This involves controlled movements that gently take muscles and joints through their full range of motion, preparing the body for activity. Dynamic stretches reduce the risk of injury by increasing blood flow and warm-up of the muscles. Examples include leg swings, arm circles, and walking lunges. In contrast, static stretching should be saved for post-exercise, as it can temporarily weaken muscle performance when performed beforehand.
