Hamstring muscle exerciser
First Claim
1. Apparatus for exercising the hamstring muscles of the human body, said apparatus comprising:
- means for supporting the body in position for articulating the knee joint;
lever means pivotally coupled with the supporting means and including leg engageable means carried by the lever means and adapted to be engaged by the users leg below the knee for swinging of the lever through a vertical arc during said articulation of the knee joint;
means biasing the lever toward the lowermost end of its path of travel, said biasing means being yieldable under the influence of force exerted through the user'"'"'s leg utilizing hamstring muscles to articulate the knee joint and thereby swing the lever through said arc;
means operably coupled with the support and with the lever respectively for limiting the arc of swing of the lever, said limiting means and said biasing means each being individually adjustable; and
said limiting means including an adjustable means for limiting both the upper and lower directional limits of the arc swing of the lever as to limit the length of the exercising stroke to that for which will involve substantially only the hamstring muscles in the swinging of the lever by the user during articulation of the knee joint.

Abstract
An exercise apparatus in the form of a bench having an L-shaped lever pivoted to the bench for swinging by the user. An adjustable weight is fastened to the lever at selectively variable locations from the pivot point for wide variations in the available resistance to exercise movements involving exercise of the hamstring muscles without undue involvement of other muscle groups. A lost motion device operable by the swinging of the lever maintains the amplitude of the exercise movement within widely adjustable limits to assist in involving primarily the hamstring muscles during the use of the apparatus. The bench pad may be covered with a fabric which is relatively resistant to the build-up of static electricity to minimize involuntary muscle stimulation when contacted by the user.
