Abstract

Thick, resilient, flexible pad with a sloped top surface and sloped sides provides for safe, non-jarring leg exercises involving running, squatting, squat-running, leg joint pivoting, balance and the like.

Claims

1. An exercise device comprising:

(a) a thick pad of resilient, flexible essentially foamed material, with a thickness of about 6-9 inches, having a lower planar surface for resting on a horizontal planar supporting surface, and an upper planar surface sloped downwardly at from 5°

to 25°

from the maximum thickness,

(b) the front and rear sides of said pad being sloped inwardly of said pad toward said upper surface, forming said upper planar surface smaller than said lower planar surface, and

(c) a top portion of resilient, flexible material being smaller than and secured on said upper planar surface with a ledge formed of said upper planar surface peripherally around said top portion, said top portion comprised of a rectangular member of resilient, flexible foamed material mounted on a rectangular base member of resilient, flexible foamed material having a center void, whereby the peripheral portions of said top portion have more resistance to compression leaving a centerwise area of less resistance.

2. An exercise device according to claim 1 wherein said rectangular member of said top portion is about 1 inch thick and said base member is about 11/2 inches thick.

3. An exercise device according to claim 1, wherein said center void is rectangular and about 8 inches square.
