text: many different systems having features of the present invention are possible . the following description describes the preferred embodiment of select features of those systems and various combinations thereof . these features may be deployed in various combinations to arrive at various desired working configurations of systems . reference is hereafter made to the drawings where like reference numerals refer to like parts throughout the various views . the present invention provides for a person to perform a swimming based exercise in a generally stationary position within a body of water while experiencing all of the benefits of free movement swimming . in order to provide these benefits structural components cooperate to perform various required functions . the required functions include placement restriction , lifting action and resilient motion . numerous structural arrangements are available to perform each of these functions and may be deployed in various combinations . an anchoring of the multiple part pole relative to the body of water , in combination with other structural components , provides for the desired placement restriction of the swimmer within the body of water . the lifting action provides the swimmer with the sensation of free swimming while being retained in a generally fixed location within the body of water . during performance of the swimming action the swimmer will be making the strokes associated with a specific swimming style in a repetitive manner . it being understood that many swimming styles may be utilized with the present invention . during performance of each stroke for any respective swimming style , as is true for conventional free swimming , various degrees of forward force will be applied by the swimmer within the water during a specific point within each of the strokes . during conventional free swimming these variations in propulsion force within each repetitive cycle of strokes would have no noticeable effect upon the swimmer . when the strokes are performed in a tethered manner it is desirable to provide for a certain degree of resilient motion at some location within the tether assembly to maintain a generally uniform pressure between the swimmer and the components of the assembly contacting the swimmer . while this resilient motion may be accommodated within various of the components , or even a combination of components , it has been discovered that the best component to provide this feature is the multiple part pole . additionally , it has been discovered that it is best to restrict this flex of the multiple part pole to the uppermost portion of the multiple part pole . this is accomplished in the preferred embodiment by providing a taper to the multiple part pole , as is conventionally known in fishing poles , where a diminishing of diametric measurement along the length of the multiple part pole restricts the flex to the outermost extent of the multiple part pole . of course , if desired , it is possible to provide certain portions of the multiple part pole to have a uniform diametric measurement rather than having a taper along the entire length of the multiple part pole . fig1 depicts a swimming exercise device 20 having a multiple part pole 22 , means to retain multiple part pole 22 , in the form of a pole mount 24 , an engagement member 26 and a connection member 28 . swimming exercise device 20 functions to allow a generally free movement of legs 30 and arms 32 of a swimmer 34 during performance of a swimming action 36 by swimmer 34 within a body of water 38 while swimmer 34 is being restricted to a generally stationary position 40 in body of water 38 . multiple part pole 22 , engagement member 26 and connection member 28 cooperate to provide for restriction of placement of swimmer 34 in body of water 38 during performance of swimming action 36 while further providing for a lifting action 42 to swimmer 34 while in body of water 38 during performance of swimming action 36 . the combination of location placement with the lifting action provides for an excellent exercise session which is extremely beneficial to overall health yet is both fun to perform and safe to perform . the present invention provides for swimmer 34 to be retained in stationary position 40 within body of water 38 , such as a swimming pool 44 , while also providing a certain amount of lift within swimming pool 44 during performance of swimming action 36 . to this end of providing for the retention in stationary position 40 multiple part pole 22 provides for securement to a fixed position relative to body of water 38 . multiple part pole 22 also provides for a certain amount of resilient motion , or flex , which is providing the resistance to swimmer 34 during performance of swimming action 36 . to the end of providing the lift during performance of the swimming action it is necessary to provide for elevation of a connection point 46 of multiple part pole 22 for connection member 28 above a surface 48 of swimming pool 44 . a multiple part pole will be provided which will perform several important functions . the multiple part pole will provide for an attachment location for the connection member elevated well above the surface of the body of water . this elevated attachment location in combination with an angle of the connection member will provide the desired lifting action to the swimmer during performance of the swimming action . additionally , a resilient flexibility of the multiple part pole will provide for resilient motion of swimmer 34 within swimming pool 44 . multiple part pole 22 has a securing end 50 , an outer end 52 and a resilient flexibility along a portion of multiple part pole 22 at least near outer end 52 . preferably , multiple part pole 22 has a gradual and consistent taper , as depicted , from securing end 50 to outer end 52 . multiple part pole 22 may be constructed from many suitable materials . multiple part pole 22 has at least two ( 2 ) portions which may be easily separated , see fig3 a and fig4 b , and easily attached , see fig3 a and fig4 a . fig7 and fig8 depict a

22 has a first end 66 and a second end 68 . first end 66 of first portion 56 has a diametric measurement 70 . second end 68 of first portion 56 has a diametric measurement 72 . diametric measurement 70 of first end 66 of first portion 56 is greater than diametric measurement 72 of second end 68 of first portion 56 . second portion 58 of multiple part pole 22 has a first end 74 and a second end 76 . first end 74 of second portion 58 has a diametric measurement 78 . second end 76 of second portion 58 has a diametric measurement 80 . diametric measurement 78 of first end 74 of second portion 58 is greater than diametric measurement 80 of second end 76 of second portion 58 . diametric measurement 70 of first end 66 of first portion 56 is generally equal to diametric measurement 80 of second
