Abstract
A highly versatile exercise apparatuses is disclosed. More particularly, the invention relates to a cable crossover exercise apparatus including a central weight stack and opposed extension arms. The invention also relates to a functional lift exercise apparatus including a central weight stack and substantially parallel extension arms. The invention further relates to a cable type exercise apparatus employing a pulley assembly with a 4:1 load ratio.
Claims20
An exercise apparatus, comprising:
- a resistance assembly;
- a cable linking a first extension arm and a second extension arm to the resistance assembly, wherein the cable includes a first strand and a second strand;
- the first extension arm includes a first end selectively supported adjacent the resistance assembly and a free second end from which the first strand of the cable extends for engagement by a user;
- the second extension arm includes a first end selectively supported adjacent the resistance assembly and a free second end from which the first strand of the cable extends for engagement by a user;
- and
- wherein the first extension arm extends away from the second extension arm, moving the second end of the first extension arm away from the second end of the second extension arm to define an extended opposed spacing of the first and second strands and the first end of the first extension arm is pivotally supported adjacent the resistance assembly at a first pivot point for rotation about a first axis, the first end of the first extension arm includes a pulley having an axis of rotation offset from the first pivot point and rotating about an axis substantially parallel to the first axis such that cable tension does not vary as the first extension arm is selectively rotated, and wherein the first end of the second extension arm is pivotally supported adjacent the resistance assembly at a second pivot point for rotation about a second axis, the first end of the second extension arm includes a pulley having an axis of rotation offset from the second pivot point and rotating about an axis substantially parallel to the second axis such that cable tension does not vary as the second extension arm is selectively rotated.
