Dynamic Tension is a self-resistance exercise method which pits muscle

, isokinetic, and some exercises in the isometric discipline.

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.

?" He concluded that lions and tigers became strong by pitting muscle against muscle. The validity of this story is questionable however and may be nothing more than an entertaining story to help sell his course. There were many other "isometric" courses available at the time and it wasn't until Atlas used the ad with the bully kicking sand in the weakling's face that the sales took off.

Specifically, dynamic tension is a technique very commonly used within martial arts. This refers to the “dynamic tension” literally applied using a person’s movements. Tightening core muscles and applying dynamic tension allows a person to change the tempo of their movement. The reconstruction of such movements gives a person more power and speed. This especially becomes useful in performing or sparring. Taking a deep breath, and exhaling slowly while tightening the muscles, and sometimes even physically shaking the body part, portrays a stronger presence while performing. Following dynamic tension could be a series of quick movements to pick up the pace. Dynamic tension is a technique that is universal and could be used on any movement or any style.
