ABSTRACT:
An isotonic exercise apparatus for stretching and strengthening leg muscles of a user comprises a body support and an exercise leg support extending outwardly therefrom. The exercise leg support is hinged to allow a user to flex an exercise leg at the knee. Conventional mechanical deadweights attached to the exercise leg support resist rotation of the exercise leg support during flexing of the exercise leg, thereby strengthening the leg of the user.
