Abstract:
In the exercise mode of operation of an exercise device during which the upper torso at the waist of a user is repetitively moved forward and back to provide lower back muscular development, an improved method consisting of obviating knee joint injury during said repetitive movements comprising the steps of:(a) determining a first length of a lower torso of an exerciser as measured from a sole to a waist of said exerciser;(b) determining a second length of a foot of said exerciser as measured from a sole to a knee joint of said exerciser;(c) providing a first support in a raised operative position correlated to said first length for an exercise at a waist junction of an upper torso and depending legs so as to permit said repetitive movements of said upper torso relative to said depending legs held in a stationary condition;(d) providing a second support in an angular relation rearwardly and below said first support and in a raised operative position correlated to said second length as a positioning site so as to be contacted by a leg area adjacent a knee joint; and(e) instructing an exerciser to assume an exercising position in contact with said first and second supports so as to cause said exerciser's femur bone and tibia bone to subtend an obtuse angle, whereby the exerciser has an optimum flexed knee condition to obviate injury to the knee joint.
