'''"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 waswere being lifted. Dynamic Dynamic-Tension exercises are not merely [[isometric exercise|isometrics]], since they call for movement. Instead, Thethe method is comprised ofcomprises a combination of exercises in three disciplines: [[isotonic (exercise physiology)|isotonic]], isokentic[[isokinetic]], and some exercises in the isometric exercisesdiscipline.

Proponents assert that it is nearly impossible to be injured during exercise using this method because one's own muscles provide the force and, as they tire, so the force used also decreases. Likewise, the benefits can continue beyond the more traditional exercise methods because as the practitioner grows stronger, the exercise becomes more intense.

After being bullied as a child, Charles Atlas joined the [[YMCA]] and began to do numerous exercise routines. He became obsessed with strength. OneHe said that one day he watched a [[tiger]] stretching in the [[zoo]] and asked himself , "How does Mr. Tiger keep in physical condition? Did you ever see a tiger with a [[barbell]]?" He concluded that [[ lionslion]] s and tigers became strong by pitting muscle against muscle. <ref>The 20th Century History With The Boring parts Left Out, D.

The phrase ''dynamic tension'' is also used in the business discipline of [[performance measurement]] to illustrate the benefits of competing priorities. People tend to behave in ways which will optimize their own rewards and recognition. If the business rewards the employee solely on one measure such as [[revenue]], the employee will be incented to make sales even when they are unprofitable. On the other hand, measuring solely on [[profit]] ratios leads to cherry-picking of sales opportunities, lost volume and higher unit costs (because the [[fixed cost]]s of production must be spread over fewer units). Any one [[key performance indicator]] can be manipulated. Rewarding employees based on ''both'' revenue and profit ratio is more complex but tends to lead to better alignment between the employees' incentives and the desired business results. Like the competing tensions of two arms pulling against each other, the two competing business priorities are said to be in dynamic tension with each other.
This principle was exemplified in the concept of the [[balanced scorecard]].
