Bridge (exercise)
Bridge is an exercise. Many variations of this exercise are employed throughout the world, most commonly the balancing of the body on the head and feet. Hands are occasionally used instead of or along with the head. It is effective in improving lower back strength. Examples of bridging in sportive or self-defense applications are seen in Kung Fu, Yoga, Judo, Brazilian jiu jitsu, Capoeira, mixed martial arts, and wrestling. The bridge can also be done starting in standing position, called a Backbend.
In yoga, this particular pose is called Chakrasana, or Wheel, while the Westernized nickname "Bridge pose" refers to a less rigorous supine backbend called Setu Bandha Sarvangasana, in which the body is fairly straight from knees to shoulders, and most of the bend is in the knees.
