There are five different types of exercise. The five types are isometric, isotonic, isokinetic, aerobic, and anaerobic . All five types of exercise serve different purposes:

Type of Exercise	Definition	Benefit	Example of Exercise
Isometric	Muscles are tightened for five to ten seconds	Develops muscular strength	Pushing against a wall
Isotonic	Muscle contraction causing movement	Builds muscular strength and improves flexibility	Swimming, walking, or running
Isokinetic	A weight or resistance is moved through an entire range of motion	Promotes flexibility, strength, and muscular endurance	Using a machine with weight plates or pressurized air for resistance
Aerobic	Exercise that requires continuous use of oxygen over an extended period of time	Develops cardiovascular endurance, some flexibility, and muscular strength	Aerobic dancing, distance swimming, or running
