         56 . The pelvis exercising system according to  claim 51 , wherein the flexible connector enables up-and-down movement of the seat. 
     
     
         57 . The pelvis exercising system according to  claim 51 , wherein the flexible connector enables clockwise and counter-clockwise rotation of the seat. 
     
     
         58 . The pelvis exercising system according to  claim 51 , further comprising a back strut configured to be pressed back by a user to engage the locking prong with the vertical support thereby locking the front-to-back movement of the seat. 
     
     
         59 . The pelvis exercising system according to  claim 58 , further comprising a back cushion connected to the back strut. 
     
     
         60 . The pelvis exercising system according to  claim 51 , wherein the seat is saddle shaped. 
     
     
         61 . The pelvis exercising system according to  claim 51 , wherein the seat is above the ground at a height restricting feet of a user from touching the ground. 
     
     
         62 . A pelvis exercising system, comprising:
 a seat;   a vertical support;   a vertical spring that is mounted between the vertical support and the seat enabling movement of the seat from a vertical position and providing a restoring force towards the vertical position; and wherein extension of a portion of the vertical support into the spring is adjustable, such that increasing the extension into the spring increases a stiffness of the spring, thereby increasing resistance to movement of the seat.   
     
     
         63 . A pelvis exercising system comprising:
 a seat;   a base;   a flexible connector mounted between the base and the seat;   a processor;   a display; and   a sensor positioned to measure movement of the seat relative to the base, wherein the sensor transmits values of the seat movement to the processor, and the processor controls the display according to the values.   
     
     
         64 . The pelvis exercising system according to  claim 63 , wherein controlling the display comprises displaying a representation of the seat movement on the display. 
     
     
         65 . The pelvis exercising system according to  claim 63 , wherein controlling the display further comprises controlling a position of a cursor on the display. 
     
     
         66 . The pelvis exercising system according to  claim 63 , wherein controlling the display further comprises controlling game play, in a game displayed on the display, according to the seat movement. 
     
     
         67 . The pelvis exercising system according to  claim 63 , wherein the sensor comprises a least one sensor selected from a group consisting of: an inertial sensor; an accelerometer; a gyroscope; and a pressure sensor. 
     
     
         68 . The pelvis exercising system according to  claim 63 , wherein the sensor is an image sensor configured to detect a position and/or inclination of the body of the user, and wherein the processor is further configured to reconstruct an image of a selected part of the body of the user and/or the seat. 
     
     
         69 . The pelvis exercising system according to  claim 63 , further comprising displaying an inclination of the seat by a ball, wherein the movement of the ball is coupled to the movement of the seat by a peripheral channel which connects the ball with the seat. 
     
     
         70 . A pelvis exercising system comprising:
 a seat, sized and shaped to support a user by his pelvis, wherein the seat comprises a front portion and a rear portion extending upwardly away from a central arch, each of the rear and front portions comprises a length which is long enough to support a front portion and rear portion of the user's pelvis, while not restricting the abdomen and lower back from bending in relation to a sagittal plane of the seat, and wherein the front and rear portions are movable in relation to each other;   a vertical support that supports the seat above the ground;   a flexible connector mounted between the vertical support and the seat.
