1. A foot training machine comprising:
- a base including a laterally extending front bar, a laterally extending rear bar, and a longitudinally extending connecting bar, said front and rear bars being arranged in a substantially parallel, longitudinally spaced relationship, said connecting bar being fixedly secured to and extending between said front and rear bars; and
first and second pedal assemblies arranged on opposite sides of said connecting bar for movement between upper and lower operating limit positions during use of said machine, each of said pedal assemblies including;
a pedal, a front rocker arm having a first end pivotally connected to said connecting bar and a second end pivotally connected to said pedal, and a rear rocker arm having a first end pivotally connected to said connecting bar and a second end pivotally connected to said pedal, said front and rear rocker arms being substantially equal in length, the distance between the pivotal connections of the front and rear rocker arms to the connecting bar being equal to the distance between the pivotal connections of the front and rear rocker arms to said pedal, the first ends of said front and rear rocker arms being pivotally connected to said connecting bar in a common substantially horizontal plane and the second ends of said front and rear rocker arms being pivotally connected to said pedal in a common substantially horizontal plane such that said pedal is maintained in a substantially horizontal plane throughout its range of movement, the lateral distance between the front rocker arm and said connecting bar being at least greater than the combined lateral distance between the rear rocker arm and said connecting bar and the width of the rear rocker arm such that said pedal can unobstructively move between said upper and lower operating limit positions.
