Exercise ball

Abstract

An exercise ball having a transparent water level indicating system is disclosed. The exercise ball has a liquid impermeable shell which creates an interior chamber and forms a covering surface for the exercise ball. The interior chamber is filled with a fluid such as water through a valve provided on the liquid impermeable shell. The valve includes an air tight closure which prevents the leakage of the fluid during exercise. A transparent portion provided on the liquid impermeable shell of the exercise ball indicates a level of the fluid filled within the interior chamber. The transparent portion includes a plurality of markings for providing direct indication of a weight of the exercise ball. A user can directly view the level of the fluid filled in the exercise ball and thereby can read a present weight of the exercise ball with the fluid.

         6 . The exercise ball of  claim 5  wherein the first end of the transparent strip is at a top portion of the exercise ball and a second end at a bottom portion of the exercise ball, a straight line connecting the first end and the second end of the transparent strip forms a diameter of the exercise ball kept in a spherical shape. 
     
     
         7 . The exercise ball of  claim 1  wherein the at least one transparent portion including the transparent strip is formed from a transparent material selected from a group of materials including plastic, any transparent elastic and flexible material. 
     
     
         8 . The exercise ball of  claim 1  wherein the plurality of markings are provided adjacent to the at least one transparent portion for providing direct indication of the weight of the exercise ball filled with the liquid. 
     
     
         9 . The exercise ball of  claim 1  wherein the plurality of markings provided adjacent to the at least one transparent portion of the exercise ball indicates the weight of the liquid filled exercise ball in kilograms 
     
     
         10 . The exercise ball of  claim 1  wherein the plurality of markings enables the user to directly read the weight of the exercise ball by comparing the level of the liquid seen through the transparent strip against the plurality of markings provided on an outer surface of the at least one liquid impermeable shell. 
     
     
         11 . The exercise ball of  claim 1  wherein a volume of the at least one liquid filled within the interior chamber of the exercise ball determines a weight of the exercise ball for a plurality of exercises, the plurality of exercises can be performed with different weights by filling and/or draining the liquid. 
     
     
         12 . The exercise ball of  claim 1  wherein the at least one liquid is filled within the interior chamber of the exercise ball through the at least one small opening and closed tight using the closure means. 
     
     
         13 . The exercise ball of  claim 1  wherein the at least one liquid filled within the interior chamber of the exercise ball includes water, the at least one liquid is colored to easily detect at least one level of the liquid through the at least one transparent portion. 
     
     
         14 . A method of using an exercise ball for practicing at least one exercise comprising the steps of:
 providing the exercise ball for practicing at least one exercise by filling in a liquid;   filling the exercise ball with a liquid through at least one small opening provided on at least one liquid impermeable shell forming at least one covering surface of the exercise ball;   checking the weight of the exercising ball through a transparent portion provided on the liquid impermeable shell of the exercise ball;   closing the at least one small opening using a closure means, the closure means seals the at least one small opening liquid tight; and   employing the exercise ball for performing a plurality of exercises by a user.   
     
     
         15 . The method of  claim 14  wherein the liquid is filled through the at least one small opening provided on the at least one liquid impermeable shell using a pumping means, the at least one liquid impermeable shell forming the at least one covering surface of the exercise ball. 
     
     
         16 . The method of  claim 14  wherein the at least one small opening provided on the at least one liquid impermeable shell is closed tight using the closure means to employ the exercise ball for performing a plurality of exercises, the plurality of exercises can be performed with different weights by filling and/or draining the liquid. 
     
     
         17 . The method of  claim 14  wherein the liquid is filled through the at least one small opening into an interior chamber defined by the at least one liquid impermeable shell, a volume of the liquid filled within the interior chamber of the exercise ball determines a weight of the exercise ball desired by the user for an exercise.
