center of the horizontal resilient surface 52 a first cable 58 is connected to the first anchor 54 the first cable 58 thereafter runs over a first upper pulley 59 and a first lower pulley 60 before passing around an end pulley 71 which is rotatably mounted on the outer end of a rod 72 that extends from the hydraulic system 50 the first cable 58 is then attached to the hydraulic system 50 also attached to the hydraulic system 50 is a second cable 81 which proceeds to pass around the end pulley 71 a reverse pulley 82 a second lower pulley 83 and a second upper pulley 62 before connecting to the second anchor 55 preferably a first exercise grip 63 is attached to the first resilient band 56 and a second exercise grip 64 is attached to the second resilient band 57 so that the participant can pull on the first resilient band 56 and the second resilient band 57 to exercise the participant 39 s upper extremities operation of the hydraulic system 50 can be understood by referring to fig9 in connection with fig8 the hydraulic system 50 has a first hydraulic cylinder 73 and a second hydraulic cylinder 74 the first hydraulic cylinder 73 contains.
