[0002] The present invention relates to exercising machines and
more particularly, to an exerciser that is practical for exercising
the muscles of different portions of the body.
[0003] 2. Description of the Related Art
[0004] Due to limited open field space and free time, people living
in cities usually use exercising machines to exercise the body
physically. Various exercising apparatus are commercially available
for exercising the hands and/or the legs. A pectoral fly machine,
which is so-called as butterfly machine, is known for exercising
the muscles of the chest and the arms. During operation, the user
hold the grips of the butterfly machine with the hands and rest the
arms on the cushion, and then move the hands alternatively forwards
and backwards to exercise the muscles of the chest. A stretching
machine is known for exercising the muscles of the back. When using
this design of stretching machine, the user holds the grips of the
machine with the hands, and then pulls the grips downwards toward
the chest and then releases the pressure repeatedly.
[0005] The aforesaid butterfly machine and stretching machine
provide only one operation mode and can only exercise one specific
part of the body. For exercising the muscles of the chest and the
back, the user has to use these two different exercising
machines.
[0006] Further, there is known a combination exerciser, which is a
combination of a butterfly machine and a stretching exerciser.
However, this design of combination exerciser can simply exercise
the muscles of the chest and the back, not practical for exercising
other parts of the body.
[0007] Further, dumbbells are commonly used for exercising the
muscles of the human body. However, because conventional dumbbells
have a fixed weight, they cannot satisfy different exercising
requirements. If a user uses an overweight dumbbell to exercise the
muscles of the arms, an athletic injury may occur easily. Further,
when using a dumbbell or dumbbells to exercise the muscles of the
arms, the dumbbell or dumbbells may fall to the ground to injure
the user's feet accidentally. Therefore, it is not safety to use
conventional dumbbells to exercise the muscles of the arms.

can stand on the floor adjacent to the base 11 and hold the grips
20 with the hands and then pull the grips 20 downwards to the
chest. At this time, the cord members 19 are moved to rotate the
rollers 18 and the guide pulleys 134 and to lift the weight holders
14 and the weights 15 on the weight holders 14 upwards toward the
limiters 16. The user can then release the force applied on the
grips 20 when the weight holders 14 strike the limiters 16.
Thereafter, this exercising procedure is repeated again and again
to exercise the muscles of the back and the arms.
[0037] Referring to FIG. 5, the user can stand on the floor
adjacent to the base 11 and hold the grips 20 with the hands and
then pull the grips 20 forwards and downwards toward to the chest.
At this time, the cord members 19 are moved to rotate the rollers
18 and the guide pulleys 134 and to lift the weight holders 14 and
the weights 15 on the weight holders 14 upwards toward the limiters
16. The user can then release the force applied on the grips 20
when the weight holders 14 strike the limiters 16. Thereafter, this
exercising procedure is repeated again and again to exercise the
muscles of the back.
[0038] Referring to FIG. 6, the user can stand on the floor
adjacent to the base 11 and hold the grips 20 with the hands and
then pull the grips 20 downwards to the chest and then move the
hands gradually toward each other. At this time, the cord members
19 are moved to rotate the rollers 18 and the guide pulleys 134 and
