Claim One:
1. A device for in-place swimming, said device comprising: structural tank defining means having a first portion with dimensions to contain a predetermined quantity of liquid just sufficient to enable an in-place swimmer to execute strokes common to normal swimming without appreciable extra liquid quantities being contained by said first portion, and a second portion for providing at least support means contiguous to said first portion; and restraint means having a first portion including belt means adapted to be releasably secured about the body of a swimmer in said liquid, and slidable fastening means having a first unit extending along said belt means a distance sufficient to substantially span the width of the body of a swimmer wearing said belt means with said first unit being connected with said first portion of said restraint means adjacent to the opposite sides of the width of the body of a swimmer wearing said belt means, and a second unit cooperable with said first unit to allow sliding movement of said second unit substantially entirely along said first unit between said connections of said first unit to said first portion of said restraint means so that said second unit can slide along substantially the entire width of the body of a swimmer, and said restraint means also having a second portion physically connected with said support means and said second unit of said slidable fastening means, said second portion of said restraint means including force means for at least exerting a force on a swimmer opposing forward movement of said swimmer from a predetermined position in said liquid due to the forwardly force exerted by said swimmer when executing said strokes common to normal swimming so that said swimmer, when secured to said restraint means, is able to swim in a normal manner and yet remain substantially in place in said liquid to thereby avoid contact with said structural means while swimming in said normal manner.
