Abstract:
A system for providing aerobic exercise comprising:a) a supporting, non-flexible base for mounting components of said system and for removably attaching said system to a rigid surface;b) a single, two-ended flexible cord, with snap connector means at both ends for removably attaching hand grips;c) first and second ports, each having a throat and located at opposed ends of said base for receiving therethrough said cord, two pulleys for guiding movement of said cord within said base and guide means associated with each pulley for assuring contact between each said pulley and said cord;d) a drum rotatably attached to said base on a drum shaft located between said pulleys and around which one or more turns of the cord is wrapped, and whose surface has a high coefficient of friction to prevent slippage of said cord;e) a direction-rectify device attached to said base and driven by said drum, such that an output shaft thereof always rotates in a same direction regardless of the rotation direction of said drum;f) a flywheel rotatable about an axis and attached to and driven by said output shaft at said axis, said flywheel having a radius of rotation larger than the radius of said drum, said flywheel having an annular disk at or near its outer periphery for applying retarding forces; andg) means for applying a frictional retarding force to said disk portion.
