Abstract:
An exercise device for supporting a left and right foot of a user and allowing alternate successive raising and lowering action of each foot while supporting the body for exercise of the user, said device comprising:a base defining a first and second fluid containing chamber, each chamber having substantially rigid sides and bottom and an open topa first elastic membrane portion and a second elastic membrane portion overlying said first and second chambers respectively sealing each open top and to closely support the left and right foot of a user above the ground,said elastic membrane portions being arranged to support the weight of a user without the left or right foot touching the ground,a fluid contained within said first and second chambers and a fluid passageway between said chambers so that foot pressure acting on fluid in either of said chambers causes movement through said passageway of said fluid at a defined rate to said other chamber and causes said fluid to exert an upward or outward pressure on a membrane portion, so that elastic stretching of either membrane portion causes elastic stretching of the other membrane portion in succession,said passageway being of predetermined size to determine resistance to flow of said fluid.
