Weight Ratio Arrangement for a Weight Machine

A cable and pulley arrangement for an exercise machine, comprising:

• a weight ratio pulley arrangement engaged with the support frame, the weight stack, and an attachment extending from the support frame, the weight ratio arrangement comprising:
• an exercise cable having a first end and a second end, the first end being connected to the attachment and the second end being connected to a portion of the support frame;
• and
• at least two movable pulley blocks, each movable pulley block including at least one pulley,
• a weight stack pulley arrangement engaged with the support frame, the weight stack, and one of the movable pulley blocks of the weight ratio pulley arrangement, the weight stack pulley arrangement comprising
• a weight stack cable having a first and a second end, the first end connected to the weight stack and the second end connected to the support frame, wherein the weight stack cable is in operative connection with one of the movable pulley blocks of the weight ratio pulley arrangement;
• and
• a locking mechanism movable between a locked position in which only one movable pulley block is movable and an unlocked position in which the two movable pulley blocks are movable.

A method of operating an exercise machine, comprising:

• (a) setting a locking mechanism on a support frame of the exercise machine to either an unlocked or locked position;
• (b) pulling an exercise cable relative to a support frame of the exercise machine;
• and
• (c) with the locking mechanism in the unlocked position, upon pulling the exercise cable, pulling at least two movable pulley blocks that in turn pulls a weight stack operatively connected to one of the movable pulley blocks via a weight stack cable;
• or
• (d) with the locking mechanism in the locked position, upon pulling the exercise cable, pulling one movable pulley block that in turn pulls a weight stack operatively connected to the movable pulley block.
