Abstract:
An exercise apparatus, comprising:a substantially planar panel having first and second side edges; andan adjustment assembly mounted between the first and second side edges for controlling the resistance to movement of the panel through a viscous fluid, the adjustment assembly comprising:a plurality of linearly aligned openings extending through the panel at spaced intervals between the first and second side edges, anda shutter having a plurality of linearly aligned alternating openings and blanks, wherein the shutter is carried by the panel for movement in a reciprocally linear direction between first and second positions for evenly controlling the size of each one of the plurality of openings of the panel for controlling the resistance to movement of the panel through a viscous fluid, wherein in and between the first and second positions of shutter the resistance is evenly distributed between the first and second side edges of the panel, each one of the plurality of openings of the shutter alignable with a selected one of the plurality of openings of the panel in one of the first and second positions of the shutter and each one of the plurality of blanks alignable to obstruct a selected one of the plurality of openings of the panel in the other one of the first and second positions of the shutter.
