'''"Dynamic Tension"''' is the name [[Charles Atlas]] gave to the system of [[physical exercise]]s that he first popularized in the 1920s.

Dynamic Tension is a self-resistance exercise method which pits [[muscle]] against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were being lifted. Dynamic Tension exercises are not merely [[isometric exercise|isometrics]], since they call for movement. Instead, the method comprises a combination of exercises in three disciplines: [[isotonic (exercise physiology)|isotonic]], [[isokinetic]], and some exercises in the isometric discipline.
