An exercise machine for exercising the hamstrings includes at least one
weight; a weight support surface below the weight; an upright weight guide
shaft laterally spaced apart from the weight; a weight displacement pedal
slidably mounted to the pedal guide shaft; a machine frame; a generally
horizontal pulley axle secured to the machine frame at a position higher
than the weight and higher than the weight displacement pedal and
laterally between the weight and the pedal guide shaft; a pulley mounted
on the pulley axle so that the pulley is rotatable relative to the machine
frame; a cable extending over and riding on the pulley and having a cable
distal end secured to the weight and having a cable proximal end secured
to the weight displacement pedal, the cable being of a length so that when
the weight rests on the weight support surface the weight displacement
pedal is elevated.
