US Patent 11925831 Arm exercise attachment

The present invention provides an upper body exercise apparatus that is portable, is compatible with various other workout machines such as stationary bikes and treadmills and is advantageous for safe, low-impact cardiovascular exercise. The exercise apparatus comprises a pair of movable handlebars that are activated by push and pull forces exerted by the user. A clamp sub-assembly is provided by which a user may attach the exercise apparatus to a separate free-standing machine, such as a stationary bike or a treadmill. A brake sub-assembly is also provided and serves to create a braking effect that results in a feeling of resistance to the user as the user moves the handlebars in a substantially forward or rearward direction.
