The document discusses the importance and components of a proper warm up routine. It notes that warming up has benefits like increasing muscle contraction speed, improving blood flow and oxygen utilization in muscles, and allowing the heart rate to rise gradually for exercise. A warm up consists of joint mobility exercises, stretching, and activation drills to prepare the body for activity. Specific joint mobility movements are described for the ankles, knees, hips, shoulders, elbows, and wrists. Activation can involve running in different ways and games help finish warming up while keeping the body temperature elevated. An example game called "el gavilan" is provided.
