Adjustable resistance based exercise apparatus

An exercise apparatus, comprising:

• a frame including a base and at least one vertical support member attached to the base;
• a resistance lever pivotably attached to the frame;
• an input actuation member connected to said resistance lever;
• a resistance engagement member moveably attached to said resistance lever, the resistance engagement member including at least one abutment bushing, said resistance engagement member being positionable at a plurality of attachment points on the resistance lever, wherein said resistance engagement member includes a selection pin;
• and
• a resistance element disposed adjacent to said resistance engagement member, said resistance element including an elastomer deflection member having a first end and a second end, a first anchor attached to and positionally fixing said first end of said deflection member, and a second anchor attached to and positionally fixing said second end of said deflection member, wherein said first anchor and said second anchor are each connected to the at least one vertical support member;
• wherein said resistance lever defines a plurality of orifices to receive said selection pin and positionally secure said resistance engagement member on said resistance lever;
• wherein said resistance lever is configured to pivot about said pivot point when a force is input to said resistance lever, and said resistance engagement member is configured to transversely engage said deflection member when a force is input to said resistance lever;
• and
• wherein a resistance provided by the resistance element is adjustable by positionally adjusting the resistance engagement member along said attachment points.

An exercise apparatus, comprising:

• a frame including a base, at least one vertical support member attached to the base, and a pivot assembly attached to said at least one vertical support member;
• a resistance lever pivotably attached to the frame;
• an input actuation member connected to said resistance lever;
• a resistance engagement member moveably attached to said resistance lever, said resistance engagement member being positionable at a plurality of attachment points on the resistance lever, and wherein said resistance engagement member includes a selection pin;
• and
• a resistance element disposed adjacent to said resistance engagement member, said resistance element including an elastomer deflection member having a first end and a second end, a first anchor attached to and positionally fixing said first end of said deflection member, and a second anchor attached to and positionally fixing said second end of said deflection member, and wherein said first anchor and said second anchor are each connected to the at least one vertical support member;
• wherein said resistance lever defines a plurality of orifices configured to receive said selection pin and positionally secure said resistance engagement member on said resistance lever;
• wherein said resistance engagement member includes a first abutment bushing and a second abutment bushing, said deflection member being disposed between said first abutment bushing and second abutment bushing;
• wherein said resistance lever is configured to pivot about said pivot point when a force is input to said resistance lever, and said resistance engagement member is configured to transversely engage said deflection member when a force is input to said resistance lever;
• wherein a resistance provided by the resistance element is adjustable by positionally adjusting the resistance engagement member along said attachment points;
• wherein said resistance engagement member is configured to have at least a first position and a second position on said resistance lever relative to said first and second anchors;
• wherein said resistance engagement member positioned in said first position deflects said deflection member a first amount in a direction substantially transverse to an axis of said deflection member in response to an angular rotation of said resistance lever;
• and
• wherein said adjustable engagement member positioned in said second position deflects said deflection member a second amount in a direction substantially transverse to the axis of said deflection member in response to said angular rotation of said resistance lever.
