Devices for exercise apparatuses

An exercise apparatus, wherein the exercise apparatus comprises a loading interface and a frame coupled to the loading interface for performing an exercise, the exercise apparatus comprising:

• a linear adjustment system that is configured to adjust an initial position of the loading interface at any one of a plurality of functional positions in a functional range of the loading interface, wherein the functional range comprises a first terminal functional position, one or more intermediate positions, and a second terminal functional position, wherein,
• the linear adjustment system comprises a first end and a second end, and
• the first end is configured to be fixedly connected to one of the loading interface and the frame;
• and
• wherein,
• the exercise exerts a muscle group of a subject through a range of motion, the range of motion comprises a first subrange that is characterized by a first maximum force that can be exerted by the subject,
• the range of motion further comprises a second subrange that is characterized by a second maximum force that can be exerted by the subject,
• the second maximum force is greater than the first maximum force,
• the initial position of the loading interface is a position in the functional range of the loading interface that permits the subject to exert a force on the loading interface with the muscle group at a point in the range of motion that is in the second subrange without any requirement of passing through the first subrange, and
• the loading interface is further from the first terminal functional position throughout the entire second subrange than it is throughout the entire first subrange.
