ABSTRACT:
Exercising devices include rotatable treads and arm supports for using both the arms and the legs, and some of the exercising devices, particularly of the treadmill type having continuous treads, are for the exercise of the legs in a walking manner and position, but in a static condition. All of the treadmill exercisers have a unitary frame having two treadmills with two continuous treads, one for each foot, and may have corresponding, separate, coordinated hand or arm exercising functions due to moveable hand braces.
