Abstract
The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.
Claims14
A fitness device for exercising the human body, the fitness device comprising in combination,
- a base frame supporting a mid-assembly and a rearward assembly,
- the mid-assembly rigidly supporting a mid-assembly pad, the mid-assembly connected to the base frame,
- the rearward assembly connected to the base frame at a horizontal distance away from the mid-assembly pad, the rearward assembly comprising
- a first member, the first member having a first end, the first end connected to a first joint, the first member rotatable about the first joint,
- a second member connected between the first joint and a second joint, the second member rotatable about the second joint,
- an adjustable connection to permit lengthening or shortening of the distance between the first and second joints,
- a third member connected to the second joint and the base frame,
- a first pair of pads connected on opposite sides of the first member, and
- a second pair of pads connected to opposite sides of the first member.
The fitness device of claim 4, the resistance device comprising a handle connected to a selectorized weight stack by a cable.
The fitness device of claim 5, further comprising a cable support structure configured to support the cable, the cable support structure comprising,
- a first arm configured to transmit force between an end of the first arm and an elbow joint,
- a second arm configured to transmit force between the elbow joint and a shoulder joint,
- the elbow joint configured to permit rotation in at least one plane, and
- the shoulder joint configured to permit rotation in at least one plane.
The fitness device of claim 6, the shoulder joint further configured to permit rotation in a second plane.
The fitness device of claim 7, the cable support structure reconfigurable to permit the handle to be selectively located.
A fitness device for exercising the human body, the fitness device comprising,
- a base frame, and
- an arm assembly, the arm assembly connected to the base frame, the arm assembly comprising,
- a first arm assembly joint rotatable about a first axis,
- a second arm assembly joint rotatable about a second axis,
- a third arm assembly joint rotatable about a third axis,
- a first arm connected between the first arm assembly joint and the second arm assembly joint,
- a second arm connected between the second arm assembly joint and the third arm assembly joint,
- and a third arm, the third arm comprising a first end and a free end, the first end connected to the third arm assembly joint, the free end extending outward from the first end in a direction perpendicular to the third axis.
