context_page_description: Warming up is a preparation for physical exertion or a performance by exercising or practising gently beforehand, usually undertaken before a performance or practice. Athletes, singers, actors and others warm up before stressing their muscles. It is widely believed to prepare the muscles for vigorous actions and to prevent muscle cramps and injury due to overexertion.
context_section_description: Stretching is part of some warm up routines, although a study in 2013 indicates that it weakens muscles in that situation. There are 3 types of stretches: ballistic, dynamic, and static:
  Ballistic Stretches involve bouncing or jerking. It is purported to help extend limbs during exercise, promoting agility and flexibility.
  Static Stretches involve flexing the muscles. This may help prevent injury and permit greater flexibility and agility.  Note that static stretching for too long may weaken the muscles.
  Dynamic Stretching involves moving the body part in the desired way until reaching the full range of motion, to improve performance.
