Flexibility exercises stretch and lengthen muscles.[5] Activities such as stretching help to improve joint flexibility and keep muscles limber.[5] The goal is to improve the range of motion which can reduce the chance of injury.[5][8]
Physical exercise can also include training that focuses on accuracy, agility, power, and speed.[9]
Types of exercise can also be classified as dynamic or static. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow.
