An elongated base frame forms generally horizontal parallel tracks which support a pair of foot support platforms and carriages for independent longitudinal movement. A vertical column has a releasable pivot connection to one end of the base frame and supports a pair of arms for 360.degree. rotational movement as a unit on a horizontal axis. Each arm is also supported for pivotal movement through an angle of about 90.degree. on an axis normal to the horizontal axis, and retractable stops provide for selecting different rotational and angular positions of the arms. A spring retractable cable reel is mounted on each arm, and a flexible cable extends from each reel around a swivel pulley on the outer end of the arm to a handle grip having a V-shaped configuration. Each of the foot support carriages has an adjustable sliding brake, and each cable reel is connected to an adjustable disk brake through a one-way clutch. The foot support carriages may be coupled together with a seat platform, and a resilient pad is supported by the column in selectable different positions.
Apparatus for performing a variety of body exercises, comprising an elongated generally horizontal base frame having first and second end portions, a pair of foot support members, means mounted on said base frame and supporting said foot members for corresponding longitudinal movement along generally parallel spaced paths, a generally vertical column having a lower end portion and an upper end portion, means for securing said lower end portion of said column to said first end portion of said base frame, a pair of arms each having inner and outer end portions, means connecting said inner end portions of said arms to said upper end portion of said column and providing for substantial rotation of said arms about a generally horizontal axis and for substantial pivotal movement of each said arm about an axis transverse to said horizontal axis, means for locking said arms at different rotary and pivoted positions, a spring retractable reel operatively connected to each said arm and having a flexible cable with a free end portion, means for directing each said cable from said outer end portion of the corresponding said arm generally horizontally regardless of the position of said arm, a handle grip member connected to said free end portion of each said cable, and a one-way clutch and adjustable brake mechanism associated with each said reel to provide for selecting the force required to extend each said cable according to the selected exercise being conducted on said apparatus.
