Adjustable crank exercise apparatus

摘要

An adjustable crank exercise apparatus is provided which a user operates while in a standing position. The apparatus includes a rotation assembly mounted on a frame structure. This rotation assembly includes a plurality of rotational members connected together by either a closed loop or intermediate rotatable members. Cranks are attached to and extend from each side of each rotational member. A pedal is located on each side which bridges the cranks on that side. The cranks are arranged such that the pedals are opposingly positioned and travel their path of rotation while remaining in a substantially horizontal position. The pedals and cranks may have adjusting features which enable the apparatus to be configured such that the foot pedals follow more of a circular path and also configured to follow more of an elliptical path. Optional handles and variable resistance provide adjustable support and multiple work levels for the user. Another option is a motor for producing automatic movement of the pedals.
