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.
