1. A portable, self-contained unit adapted for in-place exercising and strenthening the lower extremeities of the human body, comprising:
- a pair of pad members each composed of a resilient, compressible material;
common base means composed of resilient compressible material uniting said pad members in juxtaposed relation to one another whereby to define a common groove between said pad members, said pad members and said base being of unitary construction and said compressible material being of substantially uniform density throughout said pad members and said base;
each said pad member having an upper foot-engaging surface integral with each said pad member, each said pad member being generally rectangular in horizontal cross-section and having downwardly divergent side and end walls extending continuously from said upper foot-engaging surface to said common base, said side and end walls interrupted by generally convex bulge portions extending the substantial length of each of said sidewalls and end walls, said convex portions being integral with said pad members and sloping downwardly from said upper foot-engaging surface, whereby said bulges improve the lateral stability of the pad members in response to lateral deflection imparted to said pad members.

Abstract
An exercise unit for in-place exercising includes a unitary structure having a common base member with upwardly directed pads separated by a common groove, each pad terminating in an upper foot-engaging ribbed surface surrounded by a raised ledge and generally convex sidewalls and end walls which slope downwardly from the upper ribbed surfaces into the base so as to more effectively control the resistance through compression of the pads when various exercises are performed.

9. A portable, self-contained exerciser unit for in-place exercising and strengthening of the lower extremities of the human body, comprising:
-
a pair of pad members each composed of a resilient, compressible open cellular foam material; common base means composed of a resilient compressible material uniting said pad members in juxtaposed relation to one another with a common groove extending between said pad members; and each said pad member having an upper flat, foot-engaging ribbed surface formed out of and integral with each said pad member, each said pad member being generally rectangular in horizontal cross-section and having downwardly divergent side and end walls extending continuously from said upper ribbed surface to said common base, said side and end walls interrupted by generally convex bulges extending the substantial length of each of said sidewalls and end walls, said convex bulges being formed out of and integral with said pad members and extending downwardly from said upper ribbed surface, whereby said bulges improve the lateral stability of the pad members in response to lateral deflection imparted to said pad members. - View Dependent Claims (12, 13, 14)
