Modular exercise platform

Abstract

An exercise platform may include: (A) a base having a base cavity; (B) an insert that: (1) is sized to be stably received within the base cavity; and, (2) has an insert cavity; and, (C) another insert sized to be stably received within the insert cavity. The base cavity may also be sized to stably receive the base of a balance trainer and the insert cavity may also be sized to stably receive a portion of a stability ball.

1 . An exercise platform comprising:
 a base having a base cavity sized to stably receive a balance trainer;   a first insert sized to be stably received within the base cavity, the first insert comprising a substantially planar first surface and an insert cavity sized to stably receive a stability ball;   a second insert sized to be stably received within the insert cavity, the second insert comprising a substantially planar second surface; and   wherein the first and second surfaces are substantially parallel and define a user exercise surface when the first insert is stably received within the base cavity and the second insert is stably received within the insert cavity.   
   
   
       2 . The exercise platform of  claim 1  further comprising:
 a balance bar extending upwardly from the base.   
   
   
       3 . The exercise platform of  claim 2  wherein the balance bar is height adjustable. 
   
   
       4 . The exercise platform of  claim 2  wherein the balance bar is substantially U-shaped. 
   
   
       5 . The exercise platform of  claim 2  wherein the balance bar comprises:
 a ballet bar.   
   
   
       6 . The exercise platform of  claim 2  wherein the base comprises:
 a sub-frame comprising a connection portion that extends from the base and connects to a bottom portion of the balance bar.   
   
   
       7 . The exercise platform of  claim 1  further comprising:
 a first tab-in-slot connection for use in attaching the first insert to the base; and,   a second tab-in-slot connection for use in attaching the second insert to the first insert.   
   
   
       8 . The exercise platform of  claim 1  wherein:
 the first insert has a first hand grip for use in attaching the first insert to the base; and,   the second insert has a second had grip for use in attaching the second insert to the first insert.   
   
   
       9 . The exercise platform of  claim 1  wherein the outer edges of the first and second inserts are substantially circular in shape. 
   
   
       10 . The exercise platform of  claim 1  wherein the user exercise surface is substantially horizontal. 
   
   
       11 . The exercise platform of  claim 1  wherein the base has a substantially planar base surface that is substantially parallel to the first and second surfaces when the first insert is received within the base cavity and the second insert is received within the insert cavity. 
   
   
       12 . A method comprising the steps of:
 providing a base having a base cavity sized to stably receive the base of a balance trainer;   attaching a first insert, having a substantially planar first surface and an insert cavity sized to stably receive at least a portion of a stability ball, to the base within the base cavity; and,   attaching a second insert, having a substantially planar second surface, to the first insert within the insert cavity so that the first and second surfaces are substantially parallel and define a user exercise surface.   
   
   
       13 . The method of  claim 12  wherein:
 the step of, attaching the first insert, comprises the step of rotating the first insert with respect to the base; and,   the step of, attaching the second insert, comprises the step of rotating the second insert with respect to the first insert.   
   
   
       14 . The method of  claim 12  further comprising the steps of:
 detaching the second insert from the first insert; and,   placing a stability ball within the insert cavity.   
   
   
       15 . The method of  claim 12  further comprising the steps of:
 detaching the first and second inserts; and,   placing a balance trainer within the base cavity.   
   
   
       16 . The method of  claim 12  further comprising the steps of:
 detaching the first and second inserts together by detaching the first insert from the base without detaching the second insert from the first insert.   
   
   
       17 . The method of  claim 12  further comprising the step of:
 attaching a balance bar to the base.   
   
   
       18 . The method of  claim 17  further comprising the step of:
 adjusting the height of the balance bar.   
   
   
       19 . The method of  claim 13  wherein:
 the step of, rotating the first insert with respect to the base, comprises the step of engaging a first tab with a first slot; and,   the step of rotating the second insert with respect to the first insert, comprises the step of engaging a second tab with a second slot.   
   
   
       20 . The method of  claim 14  wherein the step of, detaching the second insert from the first insert, comprises the step of:
 rotating the second insert with respect to the first insert.
