Exercise device
First Claim
1. An exercise device for supporting a left and right foot of a user and allowing alternate successive raising and lowering action of each foot for exercise of said user, said device comprising:
- a first elastic membrane portion and a second elastic membrane portion in position to closely support said left and right foot of a user above the ground, a support structure for said first and second membrane portions for permitting raising and lowering movement of said left and right foot in a stair stepping action to elastically stretch said membrane portions in succession and allow return to said unstretched condition, said support structure comprising a base defining a first and second fluid containing chamber, each chamber having substantially rigid surfaces and an open top, a fluid underlying said first and second elastic membrane portions which fluid is displaced by stretching of each membrane portion and at least one passageway interconnected with said base for determining fluid flow under said first and second elastic membrane portions.

Abstract
An exercise device having two chambers, underlying two elastic membrane portions, in a position to closely support above the ground, the left and right foot respectively, of a user. A support structure such as a housing for the first and second membrane portions permit raising and lowering, as by shifting body weight, of the left and right foot in a stair stepping action, preferably without raising each foot from contact with the membrane portions to elastically stretch the membrane portions in succession. A fluid underlies the first and second elastic membrane portions. The fluid preferably is displaced by the stretching of each membrane portion and in the preferred embodiments, it acts with the membrane portions to support the body of a user in use.
