Annular exercise apparatus

Abstract

An aspect of the invention provides an annular exercise apparatus comprising an annular body having axially spaced annular faces and inner and outer side walls, the body section having a core and a flexible cover layer and defining an aperture inward of the inner side wall and extending axially through the end faces, wherein the aperture defines an annular lip having a diameter greater than a diameter of the aperture and less than a diameter of the inner side wall.

         10 . The annular exercise apparatus according to  claim 9 , further comprising a layer of resilient material provided axially outwardly of one or both of the pair of first support members and extending circumferentially between the aperture and the flexible cover layer at the outer side wall. 
     
     
         11 . The annular exercise apparatus according to  claim 9 , further comprising a layer of resilient material provided axially inwardly of one or both of the pair of first support members and extending circumferentially between the aperture and the flexible cover layer at the outer side wall. 
     
     
         12 . The annular exercise material according to  claim 9 , further comprising a layer of resilient material provided radially inward of the second support member and extending axially between the annular faces and radially between the second support member and the flexible cover layer at the inner side wall. 
     
     
         13 . The annular exercise apparatus according to  claim 9 , further comprising a layer of resilient material provided radially outward of the second support member and extending axially between the annular faces and radially between the second support member and the flexible cover layer at the outer side wall. 
     
     
         14 . The annular exercise apparatus according to  claim 9 , wherein the aperture defines an annular lip having a diameter greater than a diameter of the aperture and less than a diameter of the inner side wall. 
     
     
         15 . The annular exercise apparatus according to  claim 9 , wherein the annular lip is defined by an axially inward facing projection and a recess formed between the projection and the inner side wall and wherein the projection is provided with an anti-slip material. 
     
     
         16 . The annular exercise apparatus according to  claim 9 , wherein at least one of the annular faces is provided with an anti-slip material. 
     
     
         17 . (canceled) 
     
     
         18 . The annular exercise apparatus according to  claim 9 , wherein each of the annular faces has an outwardly facing convex profile. 
     
     
         19 . The annular exercise apparatus according to  claim 9  further comprising at least one retaining feature on at least one of the annular faces configured to attach to a corresponding retaining feature on another exercise apparatus.
