Abstract

An apparatus, a device, and corresponding methods for exercise which involve a frame having a substantially right-angle configuration for facilitating its accommodation into a corner of a room and for optimizing its footprint in the room, a pulley system having an adjustable resistance device using a pulley ratio technique, a fixed high pull mechanism, a fixed low pull mechanism, a cross-over exercise mechanism, and a lifting bar, the lifting bar having linear bearings and handles, and the handles subtending an angle in a range of approximately 0 degrees to approximately 45 degrees.

Claims (74)

1. An adjustable resistance device, comprising:

a frame;

a single pulley coupled to the frame;

a double pulley being detachably engageable with the single pulley, the device using a pulley ratio technique in its operation, wherein the double pulley comprises a bracket having a slot,

wherein the single pulley is rotatable on an axis parallel to a chord line of the single pulley, and

wherein the single pulley comprises a coupling member being insertable into the slot upon rotation of the single pulley on the axis; and

a resistance mechanism coupled to the frame, the single pulley, and the double pulley for providing resistance to the user.

2. An adjustable resistance device, comprising:

a frame;

a single pulley coupled to the frame; and

a double pulley being detachably engageable with the single pulley, the device using a pulley ratio technique in its operation,

a resistance mechanism coupled to the frame, the single pulley, and the double pulley for providing resistance to the user,

wherein tension is applied to a single cable when the double pulley is engaged with the single pulley, whereby a weight ratio of approximately 100% of an actual weight is maintained, and

wherein tension is applied to a pair of cables when the double pulley is disengaged from the single pulley, whereby a weight ratio of approximately 50% of the actual weight is maintained.

3. An adjustable resistance device, comprising:

a frame;

a single pulley coupled to the frame; and

a double pulley being detachably engageable with the single pulley, the device using a pulley ratio technique in its operation,

a resistance mechanism coupled to the frame, the single pulley, and the double pulley for providing resistance to the user;

wherein the double pulley comprises a bracket having a slot,

wherein the single pulley is rotatable on an axis parallel to a chord line of the single pulley,

wherein the single pulley comprises a coupling member being insertable into the slot upon rotation of the single pulley on the axis,

wherein tension is applied to a single cable when the double pulley is engaged with the single pulley, whereby a weight ratio of approximately 100% of an actual weight is maintained, and

wherein tension is applied to a pair of cables when the double pulley is disengaged with the single pulley, whereby a weight ratio of approximately 50% of the actual weight is maintained.

4. A method of fabricating an adjustable resistance device, comprising:
